-### Requirements
-
-##### Ruby and Jekyll
-
-Jekyll is a static site builder written in Ruby.  You will need **the latest version** of [Jekyll][jekyll] installed to build the Select2 documentation.
-
-First, [make sure that you have a Ruby environment set up][jekyll-quickstart].  Then, to install Jekyll:
-
-`gem install jekyll bundler`
-
-To upgrade Jekyll:
-
-`gem update jekyll`
-
-##### npm and Grunt
-
-Select2 uses [Grunt][grunt], which is an npm package, as a task runner. To run the build task, you will need to first [install the latest version of npm and Node.js][nodejs] as well as the [Grunt CLI][grunt-cli].
-
-### Building the docs with Grunt
-
-This assumes that you have already cloned the Select2 repo to your local development environment.  In the [main Select2 repository][select2-source], you will first need to install the npm dependencies locally:
-
-```
-npm install
-```
-
-Then, you can build and launch the documentation by running
-
-```bash
-grunt docs
-```
-
-This will start up the documentation on port 4000 ([http://localhost:4000](http://localhost:4000)). 
+Submit a pull request at [select2-new-docs][the new documentation repository].
