+### Follow named anchors
+
+This feature allows ge to follow named anchors in links of the form
+`file#anchor` or just `#anchor`, where file may omit the `.md` extension as
+usual. Two variables control its operation:
+
+```vim
+let g:vim_markdown_follow_anchor = 1
+```
+
+This tells vim-markdown whether to attempt to follow a named anchor in a link or
+not. When it is 1, and only if a link can be split in two parts by the pattern
+'#', then the first part is interpreted as the file and the second one as the
+named anchor. This also includes urls of the form `#anchor`, for which the first
+part is considered empty, meaning that the target file is the current one. After
+the file is opened, the anchor will be searched.
+
+Default is `0`.
+
+```vim
+let g:vim_markdown_anchorexpr = "'<<'.v:anchor.'>>'"
+```
+
+This expression will be evaluated substituting `v:anchor` with a quoted string
+that contains the anchor to visit. The result of the evaluation will become the
+real anchor to search in the target file. This is useful in order to convert
+anchors of the form, say, `my-section-title` to searches of the form `My Section
+Title` or `<<my-section-title>>`.
+
+Default is `''`.
