 # Sliver Docs
 
 The source code for the Sliver documentation site.
+
+### Developers
+
+To run the documentation site locally first install the dependencies and then run the `dev` npm script:
+
+```bash
+npm install
+npm run dev
+```
+
+**NOTE:** The markdown is compiled into a static JSON object at build time. This means if you edit a `.md` file you will need to restart the dev server to see your changes.
+
+### Offline Docs
+
+To run your own copy of the documentation first install the dependencies and then run the `offline` npm script:
+
+```bash
+npm install
+npm run offline
+```
+
+This will produce a `www.zip` file that contains the static html and JavaScript for the documentation site. You can extract this archive and host it anywhere:
+
+```bash
+unzip -o www.zip
+cd out/
+python -m http.server 8000
+```
+
+Then open your browser to `http://localhost:8000/` to view the documentation.
