 ## Installation
 
 For command line help, visit our wiki page on Bitters’ [command line interface](https://github.com/thoughtbot/bitters/wiki/Command-Line-Interface).
 
 1. Install the Bitters gem using the [RubyGems](https://rubygems.org) package manager:
 
   ```bash
-  gem install bitters
+  $ gem install bitters
   ```
 
   *If you use [rbenv](https://github.com/sstephenson/rbenv), be sure to run `rbenv rehash` without any errors.*
 
 2. Install [Bourbon](https://github.com/thoughtbot/bourbon#installation) (required) and [Neat](https://github.com/thoughtbot/neat#installation) (optional).
 
 3. Install the Bitters library into the current directory by running the following command at the command-line. If you’re using Ruby on Rails, run the command in `app/assets/stylesheets`:
 
   ```bash
-  bitters install
+  $ bitters install
   ```
 
   A `base` directory will be generated which contains all of the Bitters files.

   ```
