The README has always held the spotlight in a GitHub repository. You can also define relative links in your README that lets readers navigate to other files in your repository.
A relative link is a link that is, well, relative to the current file. For example, if your README is at the root of your repository, and you have another file in docs/more_words.md, the relative link to more_words.md in your README might look like this:
[Read more words!](docs/more_words.md)
GitHub will automatically transform your relative links based on whatever branch you're currently on, so that the link always works. All relative link operands (like
../) are supported. You can also provide relative paths for images!
It is not recommended to create absolute links in your READMEs with workarounds that refer to the URL, like this:
[this is wrong](https://github.com/user/repo/blob/branch/docs/more_words.md)
Users cloning your repository will have a much harder time getting the links to work as expected.
