 ## Building

-*   GNU make

+*   Node.js (>=18.12.0)
 *   npm
-*   Docker able to run amd64 containers. If running on a different platform (including Silicon Mac), you can add support for amd64 images through QEMU with:

 ## Adding OpenSCAD libraries
 
 You'll need to update 3 files (search for BOSL2 for an example):
 
-- [Makefile](./Makefile): to pull the library's code (optionally alias some files for easier imports) and package it as a `.zip` archive
+- [libs-config.json](./libs-config.json): to add the library's metadata including repository URL, branch, and files to include/exclude in the zip archive
 
 - [src/fs/zip-archives.ts](./src/fs/zip-archives.ts): to use the `.zip` archive in the UI (both for file explorer and automatic imports mounting)
 
 - [LICENSE.md](./LICENSE.md): most libraries require proper disclosure of their usage and of their license. If a license is unique, paste it in full, otherwise, link to one of the standard ones already there.
 
+### Library Configuration Format
+
+In `libs-config.json`, add an entry like this:
+
+```json
+{
+  "name": "LibraryName",
+  "repo": "https://github.com/user/repo.git", 
+  "branch": "main",
+  "zipIncludes": ["*.scad", "LICENSE", "examples"],
+  "zipExcludes": ["**/tests/**"],
+  "workingDir": "."
+}
+```
+
+Available build commands:
+- `npm run build:libs` - Build all libraries
+- `npm run build:libs:clean` - Clean all build artifacts
+- `npm run build:libs:wasm` - Download/build just the WASM binary
+- `npm run build:libs:fonts` - Download/build just the fonts
