 ## Running ReplayWeb.page
 
 To run ReplayWeb.page and view web archives, a regular HTTP server is all that is needed.
 
-ReplayWeb.page can run with any HTTP server locally. For example, you can run `http-server -p 9990` or `python -m http.server 9990` to run a static web server in the directory of this repository. Then, simply load `http://localhost:9990/` and you'll have replayweb.page running locally.

Then, load `http://localhost:9990/` and you'll have the core replayweb.page running locally.
 
 ## Developing ReplayWeb.page
 
-ReplayWeb.page is built as a Node package can be installed using yarn:

+The package provides various commands that can be used with yarn/npm. Some useful commands include:
-
-The package provides various commands that can be used with yarn:
 
 - `yarn start-dev` - to run in dev mode with Webpack dev server on port 9990. Autobuilds dev assets.
 
-- `yarn build` - to build production assets sw.js, ui.js
+- `yarn start-docs` - to build assets in dev mode, and start docs in dev mode. Autobuilds /docs assets.
 
-- `yarn start-prod` - to run production site on port 9990, with previously built assets
+- `yarn start-prod` - to run production site on port 9990, with previously built assets (without docs)
+
+- `yarn start-prod-docs` - to build production version of the site and build docs with `/docs` endpoint available.
 
 - `yarn start-electron` - to start electron in dev mode, with previously built assets
 
+- `yarn build` - to build production assets sw.js, ui.js
+
+- `yarn build-docs` - to build the docs site in `mkdocs/site` to `mkdocs/_genhtml`
+
 - `yarn dist` - to build production assets + Electron app (in dist/)
 
-The static assets are placed in the root `index.html`, `sw.js` and `ui.js`, and can be used with any HTTP server.
+### Static Site
 
-For service workers to work, they must be served from either localhost or an HTTPS endpoint.
+The static assets are placed in the root `index.html`, `sw.js`, and `ui.js`, and can be used with any HTTP server. This provides the core ReplayWeb.page functionality.
+
+### Static Site + Docs
+
+The full site with docs is built using MkDocs. Using the `yarn build-docs` command, the static assets are copied into `mkdocs/site/` and using Markdown in `mkdocs/site/docs`, the final static site is built to `mkdocs/_genhtml`. This is what is published to https://replayweb.page/ via CI.
+
+
+### Service Worker Requirements
+
+Note that for the 'backend' service worker to work, the static site must be served from either localhost or an HTTPS endpoint.
+This is browser security requirement and not much can be done to get around that.
