+### Optimizing
+
+    $ npm run optimize
+
+This command compresses and optimizes the generated js bundle. It usually allows reducing its size by ~75%, at the cost of the JavaScript code being barely readable. Use this command for deploying tooty to production.
+
 ### Deploying to gh-pages
 
     $ npm run deploy
 
 The app should be deployed to https://[your-github-username].github.io/tooty/
 
+Note: The `deploy` command uses the `optimize` one internally.
+
 ### Launching testsuite
 
     $ npm test
