 ## How to customize it
 
 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
+    npm run watch
 
-And now the grunt is watching for changes in files placed in `src/` folder. Just change what you need, and it'll run SASS preprocessor automatically.

-Regrettably, optional file include is not possible in SASS, so I would recommend creating a new file, e.g. `_my_variables.scss` and importing it a the beginning of the `application.scss` file. That way all the variables with the `!default` flag could be overridden.

+
+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";`.
+
+If you need to customize styles for [Redmine Backlogs][redmine_backlogs] remember to include your `_custom-variables.scss` in `src/sass/plugins/redmine_backlogs/_common.scss`.
