-``` sh
-bundle exec rake build
-```
-
-Then start a local web server with
+### Local Development
+```sh
+# Quick development server (faster rebuilds)
+bundle exec jekyll serve --watch --future --incremental
 
-``` sh
-bundle exec rake serve
+# Full build (for testing)
+bundle exec rake build
 ```
 
-Open [http://localhost:4000/](http://localhost:4000/)

-Alternatively, you can use Jekyll directly.
-
-```
-bundle exec jekyll serve --watch --future --incremental
+```sh
+bundle exec rake lint          # Check markdown formatting
+bundle exec rake check:markup  # Validate HTML output
+bundle exec rake check:links   # Check for broken links (requires local server)
 ```
 
-If your draft uses future date, you may want to use `--future` option.
-
-### Preview on Heroku
+You can run these tests while developing to catch issues early.
 
-In case a build is not possible on your local machine
-or you want to test your changes under production conditions
-you can also create a preview on Heroku.
