 Installation
 ------------
 
-We use [composer](http://getcomposer.org/) for dependency management, run the
-following commands under the project directory to get composer and install the
-dependency.
-
-    curl -s http://getcomposer.org/installer | php
-    php composer.phar install
+Installation is simple, just run `make` in the root directory of the source,
+you will get a `phpctags` PHAR executable, add it to your `$PATH`, then you
+can invoke `phpcatgs` directly from anywhere.
 
 See [phpctags on packagist](http://packagist.org/packages/techlivezheng/phpctags)
 for more details.
