+# Build Scripts
+
+This folder holds common build scripts accessed via the various `npm run` commands.
+Codegen is executed when calling `npm install` in order to generate all artifacts needed for the build to pass
+
+## Bundling all the code
+
+The bundling process can be split into several steps:
+
+`npm run build-css`
+This command will compile the css code and create the css file.
+
+`npm run build-prod` and `npm run build-dev`
+These commands will use rollup to bundle the code. This is where the magic happens and uses some files in this folder.
+
+`banner.ts` is used to create a banner at the beginning of the output file
+
+`rollup_plugins.ts` is used to define common plugins for rollup configurations
+
+`rollup_plugin_minify_style_spec.ts` is used to specify the plugin used in style spec bundling
+
+In the `rollup` folder there are some files that are used as linking files as they link to other files for rollup to pick when bundling.
+
+Rollup is generating 3 files throughout the process of bundling:
+
+`index.ts` a file containing all the code that will run in the main thread.
+
+`shared.ts` a file containing all the code shared between the main and worker code.
+
+`worker.ts` a file containing all the code the will run in the worker threads.
+
+These 3 files are then referenced and used by the `bundle_prelude.js` file. It allows loading the web worker code automatically in web workers without any extra effort from someone who would like to use the library, i.e. it simply works.
+
+<hr>
+
+### `npm run codegen`
+
+The `codegen` command runs the following three scripts, to update the corresponding code files based on the `v8.json` style source, and other data files. Contributors should run this command manually when the underlying style data is modified. The generated code files are then committed to the repo.
+
+#### generate-struct-arrays.ts
+
+Generates `data/array_types.ts`, which consists of:
+
+ - `StructArrayLayout_*` subclasses, one for each underlying memory layout
+ - Named exports mapping each conceptual array type (e.g., `CircleLayoutArray`) to its corresponding `StructArrayLayout` class
+ - Specific named `StructArray` subclasses, when type-specific struct accessors are needed (e.g., `CollisionBoxArray`)
+
+#### generate-style-code.ts
+
+Generates the various `style/style_layer/[layer type]_style_layer_properties.ts` code files based on the content of `v8.json`. These files provide the type signatures for the paint and layout properties for each type of style layer.
