plugins/svn-fast-info/README.md

+# svn-fast-info plugin
+
+Faster alternative to the main SVN plugin implementation. Works with svn 1.6 and newer.
+Use as a drop-in replacement to the svn plugin, not as complementary.
+
+To use it, add `svn-fast-info` to the plugins array in your zshrc file:
+```zsh
+plugins=(... svn-fast-info)
+```
+
+It's faster because his efficient use of svn (single svn call) which saves a lot on a huge codebase
+It displays the current status of the local files (added, deleted, modified, replaced, or else...)
+
+Use `svn_prompt_info` method to display the svn repository status in your theme. 
+
