+With exception of Admin Panel, Misago frontend relies heavily on React.js components backed by Django API. This application relies on custom Gulp.js-based toolkit for development. As of current, Misago's ``gulpfile.js`` defines following tasks:
 
-* **default** does production build of Misago's assets, concating and minifying javascripts, css and images, as well as moving them to misago/static directory
+* **build** does production build of Misago's assets, concating and minifying javascripts, css and images, as well as moving them to misago/static directory
 * **watch** does quick build for assets (concat assets into single files, compile less, deploy to misago/static but don't minify/optimize) as well as runs re-build when less/js changes
-* **test** runs QUnit tests suite for Misago's javascript
+* **test** runs Mocha.js tests suite for Misago's javascript
 
 To start work on custom frontend for Misago, fork and install it locally to have development forum setup. You can now develop custom theme by modifing assets in misago/frontend directory, however special care should be taken when changing source javascripts.
