Github Markdown Same Page Link
It's also possible to create named custom anchors, if for example you have a bunch of (sub-)headings with the same name. To do this with a header insert an HTML tag:
<h4 id="login-optional-fields">
Optional Fields
</h4>
Then link to it by the ID attribute:
[see above](#login-optional-fields)
Also adding an anchor tag directly to the document works as well:
<a id="my-anchor"></a>
This works on Github:
## Title
### Place 1
Hello, this is some text to fill in this, [here](#place-2), is a link to the second place.
### Place 2
Place one has the fun times of linking here, but I can also link back [here](#place-1).
### Place's 3: other example
Place one has the fun times of linking here, but I can also link back [here](#places-3-other-example).
