+## Quick Start
+
+Add this line to your Jekyll site's `Gemfile`:
+
+```ruby
+gem "minimal-mistakes-jekyll"
+```
+
+Add this line to your Jekyll site's `_config.yml` file:
+
+```yaml
+theme: minimal-mistakes-jekyll
+```
+
+Run Bundler:
+
+```bash
+bundle install
+```
+
+## Usage
+
+For detailed instructions on how to configure, customize, add content, and more read the [theme's documentation](https://mmistakes.github.io/minimal-mistakes/docs/quick-start-guide/).
+
+**Note:** Gem version of the theme requires Jekyll v3.3+ and is not supported with sites hosted with [GitHub Pages](https://pages.github.com/). You can still use the theme on GitHub Pages, you'll just need to install using the old "[repo fork method](https://mmistakes.github.io/minimal-mistakes/docs/installation/)".

 To help me out try to avoid creating pull requests on `master` and instead branch off of `develop`. It's much easier for me to test, merge, and roll them into new releases this way.
 
+Theme documentation and demo pages can be found in the `gh-pages` branch, please submit pull requests against that branch.
