+--- Add new filetype mappings.
+---
+--- Filetype mappings can be added either by extension or by filename (either
+--- the "tail" or the full file path). The full file path is checked first,
+--- followed by the file name. If a match is not found using the filename, then
+--- the filename is matched against the list of patterns (sorted by priority)
+--- until a match is found. Lastly, if pattern matching does not find a
+--- filetype, then the file extension is used.
+---
+--- The filetype can be either a string (in which case it is used as the
+--- filetype directly) or a function. If a function, it takes the full path and
+--- buffer number of the file as arguments (along with captures from the matched
+--- pattern, if any) and should return a string that will be used as the
+--- buffer's filetype.
+---
+--- Filename patterns can specify an optional priority to resolve cases when a
+--- file path matches multiple patterns. Higher priorities are matched first.
+--- When omitted, the priority defaults to 0.
+---
+--- See $VIMRUNTIME/lua/vim/filetype.lua for more examples.
+---
+--- Note that Lua filetype detection is only enabled when |g:do_filetype_lua| is
+--- set to 1.
