 Authentication
 --------------
 There are two ways to set GitHub user and token info:
 
 Using env vars GITHUB_USER and GITHUB_TOKEN:
 
-    $ export GITHUB_USER="your-github-username"
-    $ export GITHUB_TOKEN="your-github-token"
-    $ gist ~/example
+```bash
+$ export GITHUB_USER="your-github-username"
+$ export GITHUB_TOKEN="your-github-token"
+$ gist ~/example
+```
 
 Or by having your git config set up with your GitHub username and token.
 
-    git config --global github.user "your-github-username"
-    git config --global github.token "your-github-token"
+```bash
+git config --global github.user "your-github-username"
+git config --global github.token "your-github-token"
+```
 
 You can find your token under [your account](https://github.com/account).
