 A Makefile is provided to automate some tasks.
 
-* `make` will install application's dependencies via Composer and Bower,
-* `make optimize` will run Composer's autoloader dump script with classmap
+* `make` will install dependencies via composer and NPM
+* `make composer` will install PHP dependencies via composer
+* `make npm` will install CSS/JS dependencies via NPM
 * `make update` will update the application
-* `make propel` will generate propel's files
+* `make propel` will generate propel migrations (database and files)
 * `make run` will run development server on http://127.0.0.1:8080/
 
+By default, `composer`, `npm`, `git`, `mkdir` and `php` binaries must be in your `$PATH`. You can override it by using these envars:
+
+* `COMPOSER`
+* `NPM`
+* `GIT`
+* `MKDIR`
+* `PHP`
+
+For example:
+
+    $ export COMPOSER=/path/to/composer
+    $ make composer
