+
+## KittyCAD Modeling App
 
 live at [app.kittycad.io](https://app.kittycad.io/)
 
-Not sure what to call this, it's both a language/interpreter and a UI that uses the language as the source of truth model the user build with direct-manipulation with the UI.
+A CAD application from the future, brought to you by the [KittyCAD team](https://kittycad.io).
 
-It might make sense to split this repo up at some point, but not the lang and the UI are all togther in a react app
+The KittyCAD modeling app is our take on what a modern modelling experience can be. It is applying several lessons learned in the decades since most major CAD tools came into existence:
 
-Originally Presented on 10/01/2023
+- All artifacts—including parts and assemblies—should be represented as human-readable code. At the end of the day, your CAD project should be "plain text"
+  - This makes version control—which is a solved problem in software engineering—trivial for CAD
+- All GUI (or point-and-click) interactions should be actions performed on this code representation under the hood
+  - This unlocks a hybrid approach to modeling. Whether you point-and-click as you always have or you write your own KCL code, you are performing the same action in KittyCAD Modeling App
+- Everything graphics _has_ to be built for the GPU
+  - Most CAD applications have had to retrofit support for GPUs, but our geometry engine is made for GPUs (primarily Nvidia's Vulkan), getting the order of magnitude rendering performance boost with it
+- Make the resource-intensive pieces of an application auto-scaling
+  - One of the bottlenecks of today's hardware design tools is that they all rely on the local machine's resources to do the hardest parts, which include geometry rendering and analysis. Our geometry engine parallelizes rendering and just sends video frames back to the app (seriously, inspect source, it's just a `<video>` element), and our API will offload analysis as we build it in
 
-[Video](https://drive.google.com/file/d/183_wjqGdzZ8EEZXSqZ3eDcJocYPCyOdC/view?pli=1)
+We are excited about what a small team of people could build in a short time with our API. We welcome you to try our API, build your own applications, or contribute to ours!
 
-[demo-slides.pdf](https://github.com/KittyCAD/Eng/files/10398178/demo.pdf)
+KittyCAD Modeling App is a _hybrid_ user interface for CAD modeling. You can point-and-click to design parts (and soon assemblies), but everything you make is really just [`kcl` code](https://github.com/KittyCAD/kcl-experiments) under the hood. All of your CAD models can be checked into source control such as GitHub and responsibly versioned, rolled back, and more.
 
-## To run, there are a couple steps since we're compiling rust to WASM, you'll need to have rust stuff installed, then
+The 3D view in KittyCAD Modeling App is just a video stream from our hosted geometry engine. The app sends new modeling commands to the engine via WebSockets, which returns back video frames of the view within the engine.
+
+## Tools
+
+- UI
+  - [React](https://react.dev/)
+  - [Headless UI](https://headlessui.com/)
+  - [TailwindCSS](https://tailwindcss.com/)
+- Networking
+  - WebSockets (via [KittyCAD TS client](https://github.com/KittyCAD/kittycad.ts))
+- Code Editor
+  - [CodeMirror](https://codemirror.net/)
+  - Custom WASM LSP Server
+- Modeling

+## Get started
+
+We recommend downloading the latest application binary from [our Releases page](https://github.com/KittyCAD/modeling-app/releases). If you don't see your platform or architecture supported there, please file an issue.
+
+## Running a development build
+
+First, [install Rust via `rustup`](https://www.rust-lang.org/tools/install). This project uses a lot of Rust compiled to [WASM](https://webassembly.org/) within it. Then, run:
 
 ```
 yarn install
 ```
-then
+
+followed by:
+
 ```
 yarn build:wasm
 ```
+
 That will build the WASM binary and put in the `public` dir (though gitignored)
 
-finally
+finally, to run the web app only, run:
+
 ```
 yarn start
 ```
 
-and `yarn test` you would have need to have built the WASM previously. The tests need to download the binary from a server, so if you've already got `yarn start` running, that will work, otherwise running
-```
-yarn simpleserver
-```
-in one terminal
-and 
-```
-yarn test
-```
-in another.
-
-If you want to edit the rust files, you can cd into `src/wasm-lib` and then use the usual rust commands, `cargo build`, `cargo test`, when you want to bring the changes back to the web-app, a fresh `yarn build:wasm` in the root will be needed.
-
-Worth noting that the integration of the WASM into this project is very hacky because I'm really pushing create-react-app further than what's practical, but focusing on features atm rather than the setup.

+## Running tests
+
+First, start the dev server following "Running a development build" above.
+
+Then in another terminal tab, run:
+
+```
+yarn test
+```
+
+Which will run our suite of [Vitest unit](https://vitest.dev/) and [React Testing Library E2E](https://testing-library.com/docs/react-testing-library/intro/) tests, in interactive mode by default.
+
 ## Tauri
 
 To spin up up tauri dev, `yarn install` and `yarn build:wasm` need to have been done before hand then
+
 ```
 yarn tauri dev
 ```
+

+# Types
+
+`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.
+
+## Boolean
+
+`true` or `false` work when defining values.
+
+## Variable declaration
+
+Variables are defined with the `let` keyword like so:
+
+```
+let myBool = false
+```
+
+## Array
+
+An array is defined with `[]` braces. What is inside the brackets can
+be of any type. For example, the following is completely valid:
+
+```
+let myArray = ["thing", 2, false]
+```
+
+If you want to get a value from an array you can use the index like so:
+`myArray[0]`.
+
+
+## Object
+
+An object is defined with `{}` braces. Here is an example object:
+
+```
+let myObj = {a: 0, b: "thing"}
+```
+
+We support two different ways of getting properties from objects, you can call
+`myObj.a` or `myObj["a"]` both work.
+
+
+## Functions
+
+We also have support for defining your own functions. Functions can take in any
+type of argument. Below is an example of the syntax:
+
+```
+fn myFn = (x) => {
+  return x
+}
+```
+
+As you can see above `myFn` just returns whatever it is given.
+
+
+## Binary expressions
+
+You can also do math! Let's show an example below:
+
+```
+let myMathExpression = 3 + 1 * 2 / 3 - 7
+```
+
+You can nest expressions in parenthesis as well:
+
+```
+let myMathExpression = 3 + (1 * 2 / (3 - 7))
+```
+
+Please if you find any issues using any of the above expressions or syntax
+please file an issue with the `ast` label on the [modeling-app
+repo](https://github.com/KittyCAD/modeling-app/issues/new).

+## Alpha Users Expectations
+
+### Welcome
+
+First off, thank you so much for your interest in being a part of the closed Alpha program! We are thrilled to have others use our product and see what you build with it (and truthfully, how you break it too).
+
+### KittyCAD Modeling App (KCMA)
+
+What we are introducing to you is our KittyCAD Modeling App (KCMA). KCMA is a CAD application that expresses a hybrid style of traditional CAD interface along with a code-CAD interface. KCMA is a great way for us to test our own APIs as well as inspire others to develop their own applications.
+
+### Why Code?
+
+Plenty of you have professional CAD experience, and may not understand why coding your model would be helpful. The "code-CAD" paradigm isn’t as popular as traditional CAD programs (SolidWorks, NX, CREO, OnShape, etc.), but it certainly has its benefits. Some benefits include:
+
+- Automation and parametric design
+- Customization and flexibility
+- Algorithmic and generative design
+- Reproducibility
+- Easier integration with other tools
+
+### Before You Use KCMA
+
+Before you dive straight into the app, we wanted to lay some expectations out for you. 
+
+- KCMA is in early development. Kurt pitched the idea back in January, and the team has been working hard on it since then. KCMA has really basic CAD features for now, but we have plenty of features on our roadmap. Most of the features that you may be currently used to in your CAD workflow today will be available down the road.
+- For a list of all scripting functions, please reference our [documentation](https://github.com/KittyCAD/modeling-app/blob/main/docs/kcl/std.md). For a basic rundown of our types, please reference [this document](https://github.com/KittyCAD/modeling-app/blob/main/docs/kcl/types.md).
+- With that being said, we have created an external new features list in [GH Discussions](https://github.com/KittyCAD/modeling-app/discussions). For our current priority list, please click [here](https://github.com/KittyCAD/modeling-app/blob/main/public/roadmap.md). Please upvote any features in the GH Discussions page that you would like to see implemented first. We will prioritize the highest upvoted items or items that are foundational for other features on the list. You can also add your own, but we will review it to make sure it’s not a duplicate or it’s feasible for the current state of the app.
+- Please report any and all bugs/issues you find. Even the smallest bugs are important! You can report them in a GH Issue [here](https://github.com/KittyCAD/modeling-app/issues/new). You are more than welcome to link your GH Issue in the **bugs** section of our Discord, but if you want to discuss the bug further, please keep that in the GH Issue thread. Please include the severity of the bug in your GH Issue ticket (High, Medium, or Low). If you are having trouble deciding what severity the bug is, use this guideline:
+    - **High:** The bug is blocking you from continuing.
+        - Example: Every time I click the extrude button with two faces selected, the app crashes.
+    - **Medium:** You can find a workaround to the problem, but it increases your time spent working or makes it unenjoyable.
+        - Example: When the app is full screen on Mac, the settings are not showing properly. It works if I have the app windowed.
+    - **Low:** The bug is annoying but doesn’t affect workflow or block you from continuing (usually you can say “It would be nice if ___, but it’s not needed”)
+        - Example:  It would be nice if the camera would orient normal to the sketching surface when I select a face/plane and click “sketch”.
+- We want you all to be aware that we may reach out to you in regard to issues, bugs, problems, and satisfaction. This will typically be for further clarification so we can really nail things down.
+
+### Discord
+We will be using Discord a lot more now that the Alpha has been released to people outside of the company. Please feel free to discuss and talk with us in the **alpha users** section of the server. We highly encourage you to engage with us on Discord!
+
+### Thank You!
+
+Once again, from all of us to you, thank you for being a part of the closed Alpha. We are happy to chat with you all, hear your feedback, and see some of your projects!
