 In the WebRTC repo, conceptual documentation is located in `g3doc` subfolders
 of related components. To add a new document for the component `Foo` find a
 `g3doc` subfolder for this component and create a `.md` file there with
-desired documentation. If there is no `g3doc` subfolder, create a new one

+desired documentation. If there is no `g3doc` subfolder, create a new one;

+When you want to specify a link from one page to another - use the absolute
+path:
 
 ```
-config = require('/g3doc/g3doc.lua')
-return config

 ```
 
 If you are a Googler also please specify an owner, who will be responsible for
 keeping this documentation updated, by adding the next lines at the beginning
 of your `.md` file immediately after page title:
 
-```
+```markdown
 <?\% config.freshness.owner = '<user name>' %?>
 <?\% config.freshness.reviewed = '<last review date in format yyyy-mm-dd>' %?>
 ```
 
+If you want to configure the owner for all pages under a directory, create a
+`g3doc.lua` file in that directory with the content:
+
+```lua
+config = super()
+config.freshness.owner = '<user name>'
+return config
+```

 After the document is ready you should add it into `/g3doc/sitemap.md`, so it

 ### Documentation format
 
-The documentation is written in g3doc, which is a markup format derived from
-markdown. This is processed by multiple tools, so we recommend using only simple
-markup, and previewing the documents in multiple viewers if possible.
+The documentation is written in GitHub Markdown
