+## Relative Links
+
+[Relative links](https://help.github.com/articles/relative-links-in-readmes) are recommended in your Markdown files when linking to internal content.
+
+```markdown
+[Link to a header](#awesome-section)
+
+[Link to a file](docs/readme)
+```
+
+Absolute links have to be updated whenever the URL changes (e.g. repo renamed, username changed, project forked).  
+Using relative links makes your documentation easily stand on its own.

 ## .gitconfig Recommendations
 
 Your `.gitconfig` is the file that contains all your preferences.
