 ## Baseline: GitHub-Flavored Markdown
 
-The baseline for MDN Markdown is GitHub-Flavored Markdown (GFM): <https://github.github.com/gfm/>. This means that you can refer to the GFM specification for anything not explicitly specified in this page. GFM in turn is a superset of CommonMark ([https://spec.commonmark.org/](https://spec.commonmark.org/)).

 The GFM specification defines two basic types of links:
 
-- [inline links](https://github.github.com/gfm/#inline-link), in which the destination is given immediately after the link text
+- [inline links](https://github.github.com/gfm/#inline-link), in which the destination is given immediately after the link text.
 - [reference links](https://github.github.com/gfm/#reference-link), in which the destination is defined elsewhere in the document.
 
 On MDN we allow only inline links.

 - GFM tables cannot have classes assigned to them.
-- GFM doesn't support any table elements beyond `<table>`, `<tr>`, and `<th>`, and `<td>`.
