 Once in TextMate mode, completion is done against the entire directory tree at once, using partial matches. Results are sorted by "score", which is a measure of how closely the file matches the text you entered.
 
+There are several different variables that you may set in your .vimrc file that can be used to tweak the finder's behavior:
+
+* g:fuzzy_roots - this defaults to the current directory, but may be set to an array of paths that you want the finder to search.
+* g:fuzzy_ceiling - this defaults to 10,000, and is the maximum number of files that the finder will scan before it raises an error. To use the finder on larger trees, set this variable to a value larger than the number of files you expect to scan.
+* g:fuzzy_ignore - this is a semi-colon delimited list of file glob patterns to ignore.
+* g:fuzzy_match_limit - this is the maximum number of items that will be matched, and defaults to 200. If the finder feels sluggish to you, you can reduce this to something smaller (100, or 50).
