+**Triggers**: Runs on pushes to `main` when changes touch:
+- Source files in `tshtml/src/**`
+- `tshtml/package.json`
+- Documentation in `docs/**`
+- The docs workflow file itself
+- Can also be manually triggered via `workflow_dispatch`

+**What it does**:
+1. Builds TypeDoc documentation (`npm run docs`)
+2. Uploads documentation artifacts to GitHub Pages
+3. Deploys to https://xorets.github.io/tshtml/
+
+**Status**: Documentation is automatically updated on every push to `main` that affects source code or docs.

 ## Local Development (Recommended)
 
 For day-to-day development, use the monorepo’s `npm link` tooling so you can iterate on `tshtml` / `tshtml-loader` without publishing.
