-
-Before you submit a contribution PR to this repo, please ensure that:
-
-- There is a corresponding issue for the changes you want to make, so that discussion of approach can be had before work begins.
-- You have separated out refactoring commits from feature commits as much as possible
-- You have run all of the following commands locally:

-## Release a new version
-
-#### 1. Create a 'Cut release $VERSION' issue
-
-It will be used to document changelog discussions and release testing.
-
-https://github.com/KittyCAD/modeling-app/issues/new
-
-#### 2. Push a new tag
-
-Create a new tag and push it to the repo. The `semantic-release.sh` script will automatically bump the minor part, which we use the most. For instance going from `v0.27.0` to `v0.28.0`.
-
-```
-VERSION=$(./scripts/semantic-release.sh)
-git tag $VERSION
-git push origin --tags
-```
-
-This will trigger the `build-apps` workflow, set the version, build & sign the apps, and generate release files as well as updater-test artifacts.
-
-The workflow should be listed right away [in this list](https://github.com/KittyCAD/modeling-app/actions/workflows/build-apps.yml?query=event%3Apush)).
-
-#### 3. Manually test artifacts
-
-##### Release builds
-
-The release builds can be found under the `out-{arch}-{platform}` zip files, at the very bottom of the `build-apps` summary page for the workflow (triggered by the tag in 2.).
-
-Manually test against this [list](https://github.com/KittyCAD/modeling-app/issues/3588) across Windows, MacOS, Linux and posting results as comments in the issue.
-
-##### Updater-test builds
-
-The other `build-apps` output in the release `build-apps` workflow (triggered by 2.) is `updater-test-{arch}-{platform}`. It's a semi-automated process: for macOS, Windows, and Linux, download the corresponding updater-test artifact file, install the app, run it, expect an updater prompt to a dummy v0.255.255, install it and check that the app comes back at that version.
-
-The only difference with these builds is that they point to a different update location on the release bucket, with this dummy v0.255.255 always available. This helps ensuring that the version we release will be able to update to the next one available.
-
-If the prompt doesn't show up, start the app in command line to grab the electron-updater logs. This is likely an issue with the current build that needs addressing (or the updater-test location in the storage bucket).

-# Linux
-./Zoo Design Studio-{version}-{arch}-linux.AppImage
-```
-
-#### 4. Publish the release
-
-Head over to https://github.com/KittyCAD/modeling-app/releases/new, pick the newly created tag and type it in the _Release title_ field as well.
-
-Hit _Generate release notes_ as a starting point to discuss the changelog in the issue. Once done, make sure _Set as the latest release_ is checked, and hit _Publish release_.
-
-A new `publish-apps-release` will kick in and you should be able to find it [here](https://github.com/KittyCAD/modeling-app/actions?query=event%3Arelease). On success, the files will be uploaded to the public bucket as well as to the GitHub release, and the announcement on Discord will be sent.
-
-#### 5. Close the issue
-
-If everything is well and the release is out to the public, the issue tracking the release shall be closed.

-### Mapping CI CD jobs to local commands
-
-When you see the CI CD fail on jobs you may wonder three things
-
-- Do I have a bug in my code?
-- Is the test flaky?
-- Is there a bug in `main`?
-
-To answer these questions the following commands will give you confidence to locate the issue.
-
-#### Static Analysis
-
-Part of the CI CD pipeline performs static analysis on the code. Use the following commands to mimic the CI CD jobs.
-
-The following set of commands should get us closer to one and done commands to instantly retest issues.
-
-```
-npm run test-setup
-```
-
-> Gotcha, are packages up to date and is the wasm built?
-
-```
-npm run tsc
-npm run fmt:check
-npm run lint
-npm run test:unit:local
-```
-
-> Gotcha: Our unit tests have integration tests in them. You need to run a localhost server to run the unit tests.
-
-#### E2E Tests
-
-**Playwright Electron**
-
-These E2E tests run in electron. There are tests that are skipped if they are ran in a windows, linux, or macos environment. We can use playwright tags to implement test skipping.
-
-```
-npm run test:playwright:electron:local
-npm run test:playwright:electron:windows:local
-npm run test:playwright:electron:macos:local
-npm run test:playwright:electron:ubuntu:local
-```
-
-> Why does it say local? The CI CD commands that run in the pipeline cannot be ran locally. A single command will not properly setup the testing environment locally.
-
-#### Some notes on CI
-
-The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion `git reset --hard HEAD~ && git push -f` is your friend.
-
-How to interpret failing playwright tests?
-If your tests fail, click through to the action and see that the tests failed on a line that includes `await page.getByTestId('loading').waitFor({ state: 'detached' })`, this means the test fail because the stream never started. It's you choice if you want to re-run the test, or ignore the failure.
-
-We run on ubuntu and macos, because safari doesn't work on linux because of the dreaded "no RTCPeerConnection variable" error. But linux runs first and then macos for the same reason that we limit the number of parallel tests to 1 because we limit stream connections per user, so tests would start failing we if let them run together.
-
-If something fails on CI you can download the artifact, unzip it and then open `playwright-report/data/<UUID>.zip` with https://trace.playwright.dev/ to see what happened.
-
-#### Getting started writing a playwright test in our app
-
-Besides following the instructions above and using the playwright docs, our app is weird because of the whole stream thing, which means our testing is weird. Because we've just figured out this stuff and therefore docs might go stale quick here's a 15min vid/tutorial

 ### Logging
 
 To display logging (to the terminal or console) set `ZOO_LOG=1`. This will log some warnings and simple performance metrics. To view these in test runs, use `-- --nocapture`.
 
 To enable memory metrics, build with `--features dhat-heap`.
+
+## Running scripts
+
+There are multiple scripts under the folder path `./scripts` which can be used in various settings.
+
+### Pattern for a static file, npm run commands, and CI-CD checks
+
+If you want to implement a static checker follow this pattern. Two static checkers we have are circular dependency checks in our typescript code and url checker to see if any hard coded URL is the typescript application 404s. We have a set of known files in `./scripts/known/*.txt` which is the baseline.
+
+If you improve the baseline, run the overwrite command and commit the new smaller baseline. Try not to make the baseline bigger, the CI CD will complain.
+These baselines are to hold us to higher standards and help implement automated testing against the repository
+
+#### Output result to stdout
+- `npm run circular-deps`
+- `npm run url-checker`
+
+- create a `<name>.sh` file that will run the static checker then output the result to `stdout`
+
+#### Overwrite result to known .txt file on disk
+
+If the application needs to overwrite the known file on disk use this pattern. This known .txt file will be source controlled as the baseline
+
+- `npm run circular-deps:overwrite`
+- `npm run url-checker:overwrite`
+
+#### Diff baseline and current 
+
+These commands will write a /tmp/ file on disk and compare it to the known file in the repository. This command will also be used in the CI CD pipeline for automated checks
+
+- create a `diff-<name>.sh` file that is the script to diff your tmp file to the baseline
+e.g. `diff-url-checker.sh`
+```bash
+#!/bin/bash
+set -euo pipefail
+
+npm run url-checker > /tmp/urls.txt
+diff --ignore-blank-lines -w /tmp/urls.txt ./scripts/known/urls.txt
+```
+
+- `npm run circular-deps:diff`
+- `npm run url-checker:diff`
+
+## Proposing changes
+
+Before you submit a contribution PR to this repo, please ensure that:
+
+- There is a corresponding issue for the changes you want to make, so that discussion of approach can be had before work begins.
+- You have separated out refactoring commits from feature commits as much as possible
+- You have run all of the following commands locally:
+  - `npm run fmt`
+  - `npm run tsc`
+  - `npm run test`
+  - Here they are all together: `npm run fmt && npm run tsc && npm run test`
+
+## Shipping releases
+
+#### 1. Create a 'Cut release $VERSION' issue
+
+Use the **Release** issue template.
+This will be used to facilitate changelog discussions and release testing.
+
+https://github.com/KittyCAD/modeling-app/issues/new
+
+#### 2. Push a new tag
+
+Decide on a `v`-prefixed semver `VERSION` (e.g. `v1.2.3`) with the team and tag the repo on the latest main:
+
+```
+git tag $VERSION --message=""
+git push origin $VERSION
+```
+
+This will trigger the `build-apps` workflow to set the version, build & sign the apps, and generate release files.
+
+The workflow should be listed right away [in this list](https://github.com/KittyCAD/modeling-app/actions/workflows/build-apps.yml?query=event%3Apush).
+
+#### 3. Manually test artifacts
+
+The release builds can be found under the `out-{arch}-{platform}` zip files, at the very bottom of the `build-apps` summary page for the workflow (triggered by the tag in step 2).
+
+Assign someone to each section of the manual checklist generated by the issue template.
+
+#### 4. Bump the KCL version
+
+Follow the instructions [here](./rust/README.md) to publish new crates.

+KCL supports the usual arithmetic operators on numbers and logic operators on booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `+` | Addition |
+| `-` | Subtraction or unary negation |
+| `*` | Multiplication |
+| `/` | Division |
+| `%` | Modulus aka remainder |
+| `^` | Power, e.g., `x ^ 2` means `x` squared |
+| `&` | Logical 'and' |
+| `|` | Logical 'or' |
+| `!` | Unary logical 'not' |
+
+KCL also supports comparsion operators which operate on numbers and produce booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `==` | Equal |
+| `!=` | Not equal |
+| `<` | Less than |
+| `>` | Greater than |
+| `<=` | Less than or equal |
+| `>=` | Greater than or equal |
+
+Arithmetics and logic expressions can be arbitrairly combined with the usual rules of associativity and precedence, e.g.,
+
+```
+myMathExpression = 3 + 1 * 2 / 3 - 7
+```
+
+You can also nest expressions in parenthesis:
+
+```
+myMathExpression = 3 + (1 * 2 / (3 - 7))
+```
+
+KCL numbers are implemented using [floating point numbers](https://en.wikipedia.org/wiki/Floating-point_arithmetic). This means that there are occasionally representation and rounding issues, and some oddities such as supporting positive and negative zero.
+
+Some operators can be applied to other types:
+
+- `+` can be used to concatenate strings, e.g., `'hello' + ' ' + 'world!'`
+- Unary `-` can be used with planes or line-like objects such as axes to produce an object with opposite orientation, e.g., `-XY` is a plain which is aligned with `XY` but whose normal aligns with the negative Z axis.
+- The following operators can be used with solids as shorthand for CSG operations:
+  - `+` or `|` for [`union`](/docs/kcl-std/union).
+  - `-` for [`subtract`](/docs/kcl-std/subtract).
+  - `&` for [`intersect`](/docs/kcl-std/intersect)

+
+Arrays are sequences of values.
+
+Arrays can be written out as *array literals* using a sequence of expressions surrounded by square brackets, e.g., `['hello', 'world']` is an array of strings, `[x, x + 1, x + 2]` is an array of numbers (assuming `x` is a number), `[]` is an empty array, and `['hello', 42, true]` is a mixed array.
+
+A value in an array can be accessed by indexing using square brackets where the index is a number, for example, `arr[0]`, `arr[42]`, `arr[i]` (where `arr` is an array and `i` is a (whole) number).
+
+There are some useful functions for working with arrays in the standard library, see [std::array](/docs/kcl-std/modules/std-array) for details.
+
+## Array types
+
+Arrays have their own types: `[T]` where `T` is the type of the elements of the array, for example, `[string]` means an array of `string`s and `[any]` means an array of any values.
+
+Array types can also include length information: `[T; n]` denotes an array of length `n` (where `n` is a number literal) and `[T; n+]` denotes an array whose length is at least `n`. The common case for that is `[T; 1+]`, i.e., a non-empty array. E.g., `[string; 1+]` and `[number(mm); 3]` are valid array types.
+
+## Ranges
+
+Ranges are a succinct way to create an array of sequential numbers. The syntax is `[start .. end]` where `start` and `end` evaluate to whole numbers (integers). Ranges are inclusive of the start and end. The end must be greater than the start. A range which is exclusive of its end is written with `<end`. Examples:
+
+```kcl,norun
+[0..3]      // [0, 1, 2, 3]
+[3..10]     // [3, 4, 5, 6, 7, 8, 9, 10]
+[3..<10]    // [3, 4, 5, 6, 7, 8, 9]
+x = 2
+[x..x+1]    // [2, 3]
+```
+
+The units of the start and end numbers must be the same and the result inherits those units.

+title: "Attributes"
+excerpt: "Documentation of the KCL language for the Zoo Design Studio."
+layout: manual

+
+Attributes are syntax which affects the language item they annotate. In KCL they are indicated using `@`. For example, `@settings` affects the file in which it appears.
+
+There are two kinds of attributes: named and unnamed attributes. Named attributes (e.g., `@settings`) have a name immediately after the `@` (e.g., `settings`) and affect their surrounding scope. Unnamed attributes have no name and affect the following item, e.g.,
+
+```kcl,norun
+@(lengthUnit = ft, coords = opengl)
+import "tests/inputs/cube.obj"
+```
+
+has an unnamed attribute on the `import` statement.
+
+Named and unnamed attributes may take a parenthesized list of arguments (like a function). Named attributes may also appear without any arguments (e.g., `@no_std`).
+
+## Named attributes
+
+The `@settings` attribute affects the current file and accepts the following arguments: `defaultLengthUnit`, `defaultAngleUnit`, and `kclVersion`. See [settings](/docs/kcl-lang/settings) for details.
+
+The `@no_std` attribute affects the current file, takes no arguments, and causes the standard library to not be implicitly available. It can still be used by being explicitly imported.
+
+## Unnamed attributes
+
+Unnamed attributes may be used on `import` statements when importing non-KCL files. See [projects, modules, and imports](/docs/kcl-lang/modules) for details.
+
+Other unnamed attributes are used on functions inside the standard library, but these are not available in user code.

+
+`import` can also be used to import files from other CAD systems. The format of the statement is the
+same as for KCL files. You can only import the whole file, not items from it. E.g.,
+
+```norun
+import "tests/inputs/cube.obj"
+
+// Use `cube` just like a KCL object.
+```
+
+```kcl
+import "tests/inputs/cube.sldprt" as cube
+
+// Use `cube` just like a KCL object.
+```
+
+For formats lacking unit data (such as STL, OBJ, or PLY files), the default
+unit of measurement is millimeters. Alternatively you may specify the unit
+by using an attribute. Likewise, you can also specify a coordinate system. E.g.,
+
+```kcl
+@(lengthUnit = ft, coords = opengl)
+import "tests/inputs/cube.obj"
+```
+
+When importing a GLTF file, the bin file will be imported as well.
+
+Import paths are relative to the current project directory. Imports currently only work when
+using the native Design Studio, not in the browser.
+
+### Supported values
+
+File formats: `fbx`, `gltf`/`glb`, `obj`+, `ply`+, `sldprt`, `step`/`stp`, `stl`+. (Those marked with a
+'+' support customising the length unit and coordinate system).
+
+Length units: `mm` (the default), `cm`, `m`, `inch`, `ft`, `yd`.
+
+Coordinate systems:
+
+- `zoo` (the default), forward: -Y, up: +Z, handedness: right
+- `opengl`, forward: +Z, up: +Y, handedness: right
+- `vulkan`, forward: +Z, up: -Y, handedness: left

+
+## Performance deep‑dive for foreign‑file imports
+
+Parallelized foreign‑file imports now let you overlap file reads, initialization,
+and rendering. To maximize throughput, you need to understand the three distinct
+stages—reading, initializing (background render start), and invocation (blocking)
+—and structure your code to defer blocking operations until the end.
+
+### Foreign import execution stages
+
+1. **Import (Read / Initialization) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+   ```
+   - Reads the file from disk and makes its API available.
+   - Starts engine rendering but **does not block** your script.
+   - This kick‑starts the render pipeline while you keep executing other code.
+
+2. **Invocation (Blocking) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+
+   cube
+     |> translate(z=10) // ← blocks here only
+   ```
+   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
+
+### Best practices
+
+#### 1. Defer blocking calls
+
+```kcl
+import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
+
+
+// --- perform other operations and calculations here ---
+
+
+cube
+  |> translate(z=10)                        // 2) Blocks only here
+```
+
+#### 2. Split heavy work into separate modules
+
+Place computationally expensive or IO‑heavy work into its own module so it can render in parallel while `main.kcl` continues.
+
+#### Future improvements
+
+Upcoming releases will auto‑analyse dependencies and only block when truly necessary. Until then, explicit deferral will give you the best performance.

-Parallelized foreign‑file imports now let you overlap file reads, initialization,

-
-1. **Import (Read / Initialization) Stage**
-   ```kcl
-   import "tests/inputs/cube.step" as cube

-   - Reads the file from disk and makes its API available.
-   - Starts engine rendering but **does not block** your script.
-   - This kick‑starts the render pipeline while you keep executing other code.
-
-2. **Invocation (Blocking) Stage**
-   ```kcl
-   import "tests/inputs/cube.step" as cube
-
-   cube
-     |> translate(z=10) // ← blocks here only
-   ```
-   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
-
-### Best practices
-
-#### 1. Defer blocking calls
-
-```kcl
-import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
-
-
-// --- perform other operations and calculations here ---
-
-
-cube
-  |> translate(z=10)                        // 2) Blocks only here
-```
-
-#### 2. Split heavy work into separate modules
-
-Place computationally expensive or IO‑heavy work into its own module so it can render in parallel while `main.kcl` continues.
-
-#### Future improvements
-
-Upcoming releases will auto‑analyse dependencies and only block when truly necessary. Until then, explicit deferral will give you the best performance.

+---
+
+Numbers and numeric types in KCL include information about the units of the numbers. So rather than just having a number like `42`, we always have information about the units so we don't confuse 42 mm with 42 inches.
+
+
+## Numeric literals
+
+When writing a number literal, you can use a unit suffix to explicitly state the unit, e.g., `42mm`. The following units are available:
+
+- Length units:
+  - metric: `mm`, `cm`, `m`
+  - imperial: `in`, `ft`, `yd`
+- Angle units: `deg`, `rad`
+- `_` to indicate a unitless number such as a count or ratio.
+
+If you write a numeric literal without a suffix, then the defaults for the current file are used. These defaults are specified using the `@settings` attribute, see [settings](/docs/kcl-lang/settings) for details. Note that if using the defaults, the KCL interpreter won't know whether you intend the number to be a length, angle, or count and will treat it as being possibly any of them.
+
+
+## Numeric types
+
+Just like numbers carry units information, the `number` type also includes units information. Units are written in parentheses after the type, e.g., `number(mm)`.
+
+Any of the suffixes described above can be used meaning that values with that type have the supplied units. E.g., `number(mm)` is the type of number values with mm units and `number(_)` is the type of number values with no units.
+
+You can also use `number(Length)`, `number(Angle)`, or `number(Count)`. These types mean a number with any length, angle, or unitless (count) units, respectively (note that `number(_)` and `number(Count)` are equivalent since there is only one kind of unitless-ness).
+
+Using just `number` means accepting any kind of number, even where the units are unknown by KCL.
+
+
+## Function calls
+
+When calling a function with an argument with numeric type, the declared numeric type in the function signature and the units of the argument value used in the function call must be compatible. Units are adjusted automatically. For example, if a function requires an argument with type `number(mm)`, then you can call it with `2in` and the units will be automatically adjusted, but calling it with `90deg` will cause an error.
+
+
+## Mixing units with arithmetic
+
+When doing arithmetic or comparisons, units will be adjusted as necessary if possible. However, often arithmetic expressions exceed the ability of KCL to accurately choose units which can result in warnings in your code or sometimes errors. In these cases, you will need to give KCL more information. Sometimes this can be done by making units explicit using suffixes. If not, then you will need to use *type ascription*, which asserts that an expression has the supplied type. For example, `(x * y): number(mm)` tells KCL that the units of `x * y` is mm. Note that type ascription does not do any adjustment of the numbers, e.g., `2mm: number(in)` has the value `2in` (note that this would be a very non-idiomatic way to use numeric type ascription, you could simply write `2in`. Usually type ascription is only necessary for supplying type information about the result of computation).
+
+KCL has no support for area, volume, or other higher dimension units. When internal unit tracking requires multiple dimensions, KCL essentially gives up. This is usually where the extra type information described above is needed. If doing computation with higher dimensioned units, you must ensure that all adjustments occur before any computation. E.g., if you want to compute an area with unknown units, you must convert all numbers to the same unit before starting.
+
+
+## Explicit conversions
+
+You might sometimes need to convert from one unit to another for some calculation. You can do this implicitly when calling a function (see above), but if you can't or don't want to, then you can use the explicit conversion functions in the [`std::units`](/docs/kcl-std/modules/std-units) module.
+
+KCL cannot know about changes to units caused by arithmetic. For example, you may intend for `10in * 25.4` to be the value `254mm` (i.e., `10in` in mm), however, the result of that computation in KCL is `254in`. It is always better to rely on automatic conversion or to use the explicit conversion functions, where possible.
+
+Converting between degrees and radians using π ([`PI`](/docs/kcl-std/consts/std-math-PI) in KCL) is especially prone to this error and so the `PI` constant always requires specifying units of any computation it is used with. E.g., `radius = (circumference / (2 * PI)): number(mm)`.

+
+It can be hard to read repeated function calls, because of all the nested brackets.
+
+```norun
+i = 1
+x = h(g(f(i)))
+```
+
+You can make this easier to read by breaking it into many declarations, but that is a bit annoying.
+
+```norun
+i  = 1
+x0 = f(i)
+x1 = g(x0)
+x  = h(x1)
+```
+
+Instead, you can use the pipeline operator (`|>`) to simplify this.
+
+Basically, `x |> f(%)` is a shorthand for `f(x)`. The left-hand side of the `|>` gets put into
+the `%` in the right-hand side.
+
+So, this means `x |> f(%) |> g(%)` is shorthand for `g(f(x))`. The code example above, with its
+somewhat-clunky `x0` and `x1` constants could be rewritten as
+
+```norun
+i = 1
+x = i
+  |> f(%)
+  |> g(%)
+  |> h(%)
+```
+
+This helps keep your code neat and avoid unnecessary declarations.
+
+## Pipelines and keyword arguments
+
+Say you have a long pipeline of sketch functions, like this:
+
+```norun
+startSketchOn(XZ)
+  |> line(%, end = [3, 4])
+  |> line(%, end = [10, 10])
+  |> line(%, end = [-13, -14])
+  |> close(%)
+```
+
+In this example, each function call outputs a sketch, and it gets put into the next function call via
+the `%`, into the first (unlabeled) argument.
+
+If a function call uses an unlabeled first parameter, it will default to `%` if it's not given. This
+means that `|> line(%, end = [3, 4])` and `|> line(end = [3, 4])` are equivalent! So the above
+could be rewritten as 
+
+```norun
+startSketchOn(XZ)
+ |> line(end = [3, 4])
+ |> line(end = [10, 10])
+ |> line(end = [-13, -14])
+ |> close()
+```

+
+`KCL` defines the following types and keywords the language.
+
+All these types can be nested in various forms where nesting applies. Like
+arrays can hold objects and vice versa.
+
+## Constant declaration
+
+Constants are defined with a name and a value, like so:
+
+```
+myBool = false
+```
+
+Currently you cannot redeclare a constant.
+
+
+## Objects
+
+An object is defined with `{}` braces. Here is an example object:
+
+```
+myObj = { a = 0, b = "thing" }
+```
+
+To get the property of an object, you can call `myObj.a`, which in the above
+example returns 0.
+
+## `ImportedGeometry`
+
+Using `import` you can import geometry defined using other CAD software. In KCL,
+these objects have type `ImportedGeometry` and can mostly be treated like any
+other solid (they can be rotated, scaled, etc.), although there is no access to
+their internal components. See the [modules and imports docs](modules) for more
+detail on importing geometry.
+
+
+## Tags
+
+Tags are used to give a name (tag) to a specific path.
+
+### Tag declarations - `TagDecl`
+
+The syntax for declaring a tag is `$myTag` you would use it in the following
+way:
+
+```norun
+startSketchOn(XZ)
+  |> startProfile(at = origin)
+  |> angledLine(angle = 0, length = 191.26, tag = $rectangleSegmentA001)
+  |> angledLine(
+       angle = segAng(rectangleSegmentA001) - 90,
+       length = 196.99,
+       tag = $rectangleSegmentB001,
+     )
+  |> angledLine(
+       angle = segAng(rectangleSegmentA001),
+       length = -segLen(rectangleSegmentA001),
+       tag = $rectangleSegmentC001,
+     )
+  |> line(endAbsolute = [profileStartX(%), profileStartY(%)])
+  |> close()
+```
+
+When a function requires declaring a new tag (using the `$` syntax), the argument has type [`TagDecl`](/docs/kcl-std/types/std-types-TagDecl).
+
+### Tag identifiers
+
+A tag created using a tag declarator can be used by writing its name without the `$`, e.g., `myTag`.
+Where necessary to disambiguate from tag declarations, we call these tag identifiers.
+
+In the example above we use the tag identifier `rectangleSegmentA001` to get the angle of the segment
+using `segAng(rectangleSegmentA001)`.
+
+Tags can identify either an edge or face of a solid, or a line or other edge of a sketch. Functions
+which take a tag identifier as an argument will use either [`TaggedEdge`](/docs/kcl-std/types/std-types-TaggedEdge) (for the edge of a
+solid or sketch) or [`TaggedFace`](/docs/kcl-std/types/std-types-TaggedFace).
+
+If a line in a sketch is tagged and then the sketch is extruded, the tag is a `TaggedEdge` before
+extrusion and a `TaggedFace` after extrusion.
+
+#### `START` and `END`
+
+[`START`](/docs/kcl-std/consts/std-START) and [`END`](/docs/kcl-std/consts/std-END) are special tags
+for identifying the starting and ending faces of an extruded solid.
+
+
+### Tag Scope
+
+Tags are scoped globally if in the root context meaning in this example you can 
+use the tag `rectangleSegmentA001` in any function or expression in the file.
+
+However if the code was written like this:
+
+```norun
+fn rect(origin) {
+  return startSketchOn(XZ)
+    |> startProfile(at = origin)
+    |> angledLine(angle = 0, length = 191.26, tag = $rectangleSegmentA001)
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001) - 90,
+         length = 196.99,
+         tag = $rectangleSegmentB001,
+       )
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001),
+         length = -segLen(rectangleSegmentA001),
+         tag = $rectangleSegmentC001,
+       )
+    |> line(endAbsolute = [profileStartX(%), profileStartY(%)])
+    |> close()
+}
+
+rect(origin = [0, 0])
+rect(origin = [20, 0])
+``` 
+
+Those tags would only be available in the `rect` function and not globally.
+
+However you likely want to use those tags somewhere outside the `rect` function.
+
+Tags are accessible through the sketch group they are declared in.
+For example the following code works.
+
+```norun
+fn rect(origin) {
+  return startSketchOn(XZ)
+    |> startProfile(at = origin)
+    |> angledLine(angle = 0, length = 191.26, tag = $rectangleSegmentA001)
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001) - 90,
+         length = 196.99,
+         tag = $rectangleSegmentB001,
+       )
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001),
+         length = -segLen(rectangleSegmentA001),
+         tag = $rectangleSegmentC001,
+       )
+    |> line(endAbsolute = [profileStartX(%), profileStartY(%)])
+    |> close()
+}
+
+rect(origin = [0, 0])
+myRect = rect(origin = [20, 0])
+
+myRect
+  |> extrude(length = 10)
+  |> fillet(radius = 0.5, tags = [myRect.tags.rectangleSegmentA001])
+```
+
+See how we use the tag `rectangleSegmentA001` in the `fillet` function outside
+the `rect` function. This is because the `rect` function is returning the
+sketch group that contains the tags.
