 == Using the documentation browser
 
-Documentation buffers are like any other buffer,
-so you can scroll through them as normal,
-search within a topic with `/`, etc.
-However, they can also contain links: <<doc#demonstration-target,like this>>.
-Links can be followed by moving the cursor onto them and pressing Enter.
-If a link takes you to a different documentation topic,
-you can return to the original by using the `:buffer` command.

 == Writing documentation
 
 Documentation must be in AsciiDoc format, with the extension `.asciidoc`.
-It must be stored somewhere within <<doc#sources,the documentation search path>>.
-Kakoune's built-in documentation renderer does not necessarily support every feature,
-so don't go overboard with formatting.

-To create a link to another documentation topic,
-the URL should be the topic's name, just like `:doc` uses.
-Because topics are identified only by their basename,
-you should take care that your topic's name does not conflict with any of the names used either by other plugins or by Kakoune's standard library.
