 - OpenOCD output varies between versions. Parsers must handle multiple formats; check existing regex patterns before assuming a single format.
 - The sync API must never be called from inside an already-running async event loop (guarded in `SyncSession._get_or_create_loop()`).
 - Date-based versioning: `YYYY.MM.DD` format.

+## Documentation Site
+
+Live docs are at **https://openocd-python.warehack.ing** (Starlight/Astro, 28 pages).
+
+Source repo: `git@git.supported.systems:warehack.ing/openocd-python-docs.git`
+
+Deployment (remote server):
+```bash
+ssh -A warehack-ing@openocd.warehack.ing "cd openocd-python-docs && git pull && make prod"
+```
+
+When adding or changing library API surface (new subsystems, types, exceptions, methods), update the corresponding docs pages:
+- `guides/` -- usage guides with async/sync tabs
+- `reference/types.mdx` -- frozen dataclass tables
+- `reference/exceptions.mdx` -- error hierarchy
+- `reference/method-index.mdx` -- method signatures
+- `index.mdx` -- subsystem count on homepage
+- `astro.config.mjs` -- sidebar entries

+## Publishing to PyPI
+
+```bash
+uv build
+uv publish dist/openocd_python-<version>* --username __token__ --password "$(python3 -c "import configparser; c=configparser.ConfigParser(); c.read('$HOME/.pypirc'); print(c['pypi']['password'])")"
+```
+
+## Git Workflow
+
+This repo lives as a subtree inside the `mcjtag` monorepo. Push to the Gitea remote via:
+```bash
+cd ~/claude/mcjtag && git subtree push --prefix=openocd-python origin main
+```
