 If you want to customize PurpleMine to your needs, first, make sure that you have installed [node.js](http://nodejs.org/) and `npm` is available in your terminal.
 
-If haven't yet, you need to install grunt:
-
-    npm install grunt-cli -g
-
 Then, from the directory that contains PurpleMine run:
 
     npm install
 
 Now all the dependencies should be ready to use. Run one more command:
 
-    grunt watch

 The path `src/sass/_custom-variables.scss` is added to `.gitignore` so it should make upgrading PurpleMine with keeping your changes rather painless, given that the only thing you changed in PurpleMine's source was adding this one line with `@import "custom-variables";`.
