 ## 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. We always use the latest stable version of Rust, so you may need to run `rustup update stable`. Then, run:
+Install a node version manager such as [fnm](https://github.com/Schniz/fnm?tab=readme-ov-#installation).
 
+On Windows, it's also recommended to [upgrade your PowerShell version](https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.5#winget), we're using 7.
+
+Then in the repo run the following to install and use the node version specified in `.nvmrc`. You might need to specify your processor architecture with `--arch arm64` or `--arch x64` if it's not autodetected. 
+```
+fnm install --corepack-enabled
+fnm use

 ```

 That will build the WASM binary and put in the `public` dir (though gitignored).

+## Importing files from other CAD systems
+
+`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.,
+
+```
+import "tests/inputs/cube.obj"
+
+// Use `cube` just like a KCL object.
+```
+
+```
+import "tests/inputs/cube-2.sldprt" as cube
+
+// Use `cube` just like a KCL object.
+```
+
+You can make the file format explicit using a format attribute (useful if using a different
+extension), e.g.,
+
+```
+@(format = obj)
+import "tests/inputs/cube"
+```
+
+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 attirbute. Likewise, you can also specify a coordinate system. E.g.,
+
+```
+@(unitLength = 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 Modeling App, not in the browser.
+
+### Supported values
