 ### Concealing
 
-Concealing is set for some syntax such as bold, italic, code block and link.
+Concealing is a vim feature that lets you visually replace text with another text. The actual source text is not modified. See `:h conceallevel` and `:h concealcursor` for vim's official documentation on this feature.

-    For example, conceal `[link text](link url)` as just `link text`.
-    Also, `_italic_` and `*italic*` will conceal to just _italic_.
-    Similarly `__bold__`, `**bold**`, `___italic bold___`, and `***italic bold***`
-    will conceal to just __bold__, **bold**, ___italic bold___, and ***italic bold*** respectively.

-    To enable conceal use Vim's standard conceal configuration.

+    As you can see, simple LaTeX math concealing works well, but it breaks if the LaTeX code gets more involved.
