 ## Installation
 SublimeLinter must be installed in order to use this plugin. 
 
 Please use [Package Control](https://packagecontrol.io) to install the linter plugin.
 
-Before installing this plugin, you must ensure that `__linter__` is installed on your system.
+Before installing this plugin, you must ensure that `groovyc` is installed on your system.
 
-In order for `__linter__` to be executed by SublimeLinter, you must ensure that its path is available to SublimeLinter. The docs cover [troubleshooting PATH configuration](http://sublimelinter.readthedocs.io/en/latest/troubleshooting.html#finding-a-linter-executable).
