+1. Bump the versions by running `./make-realease.sh` while on a fresh pull of main
 
-```bash
+That will create the branch with the updated json files for you.
-VERSION=x.y.z yarn run bump-jsons
-```
-
-Alternatively you can try the experimental `make-release.sh` bash script that will create the branch with the updated json files for you.
 run `./make-release.sh` for a patch update
 run `./make-release.sh "minor"` for minor
 run `./make-release.sh "major"` for major
 
-The PR may serve as a place to discuss the human-readable changelog and extra QA. A quick way of getting PR's merged since the last bump is to [use this PR filter](https://github.com/KittyCAD/modeling-app/pulls?q=is%3Apr+sort%3Aupdated-desc+is%3Amerged+), open up the browser console and paste in the following
+After it runs you should just need to push the push the branch and open a PR (it will suggest a changelog for you too, delete any that are not user facing)
 
-```typescript
+The PR may serve as a place to discuss the human-readable changelog and extra QA. 
-console.log(
-  '- ' +
-    Array.from(
-      document.querySelectorAll('[data-hovercard-type="pull_request"]')
-    ).map((a) => `[${a.innerText}](${a.href})`).join(`
-- `)
-)
-```
 
-grab the md list and delete any that are older than the last bump
+2. Smoke test the artifact from the above PR
+We don't have a strict process, but click around and check for anything obvious
+One of the artifacts is called updater-test, because we don't have a way to test this fully automated, we have a semi-automated process.
 
-2. Merge the PR
+Download updater-test zip file, install the app, run it, expect an updater prompt to v0.99.99, install it and check that the app comes back at that version (on both macOS and Windows).
+
+3. Merge the PR
+
+
+4. Profit (A new Action kicks in at https://github.com/KittyCAD/modeling-app/actions if the PR was correctly named)
 
-3. Create a new release and tag pointing to the bump version commit using semantic versioning `v{x}.{y}.{z}`
 
-4. A new Action kicks in at https://github.com/KittyCAD/modeling-app/actions, uploading artifacts to the release

 ```
 
-Please if you find any issues using any of the above expressions or syntax
+## Tags
+
+Tags are used to give a name (tag) to a specific path.
+
+### Tag Declaration
+
+The syntax for declaring a tag is `$myTag` you would use it in the following
+way:
+
+```
+startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+```
+
+### Tag Identifier
+
+As per the example above you can use the tag identifier to get a reference to the 
+tagged object. The syntax for this is `myTag`.
+
+In the example above we use the tag identifier to get the angle of the segment
+`segAng(rectangleSegmentA001, %)`.
+
+
+### 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:
+
+```
+fn rect = (origin) => {
+  return startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+}
+
+rect([0, 0])
+rect([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.
+
+```
+fn rect = (origin) => {
+  return startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+}
+
+rect([0, 0])
+const myRect = rect([20, 0])
+
+myRect 
+  |> extrude(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.
+
+
