+
+qfc is a shell auto-complete alternative which features real-time multi-directories matching: It provides results  while you type against files in the current directory and its sub-directories.
+This is useful, to avoid the burden of writing the whole path whenever you want to `cd` or `vim` a file, which is frequent especially if you use the terminal as your IDE(The terminal is the best IDE, remember! :-) ).
+
+
+## Features:
+- Real-time matching: Results are displayed while you type.
+- Multi-directories && Context relevant matching: if you're in a cvs(git,mercurial) managed directory, qfc will matches against your tracked(or new) files only. This is very useful to avoid 10000+ of dependency files cluttering up the results. for unmanaged dirs, qfc looks for unhidden files up to a maximum depth(set to 3).
+- Enhanced Filtering/Sorting of matches.
+- No dependencies.
+
+
+## Requirements
+- python (2.7+ or 3.0+)
+- Bash-4.0+ or Zshell.
+- Linux Or OSX  
+In OSX, it seems like Bash 3.x is the default shell which is not supported. you have to [update your Bash to 4.0+](http://apple.stackexchange.com/a/24635) or [change your shell to zshell](http://stackoverflow.com/a/1822126/1117720).
+
+
+## Installation:
+- `git clone https://github.com/pindexis/qfc $HOME/.qfc`
+- Add the following line to your *rc (.zshrc, .bashrc, .bash_profile in OSX):  
+    `[[ -s "$HOME/.qfc/bin/qfc.sh" ]] && source "$HOME/.qfc/bin/qfc.sh"`
+
+
+## Usage:
+- `Ctrl-f` : complete the word under cursor using qfc
+- while qfc is open:
+    - `TAB`: Append the selected match to the current path.
+    - `ENTER`: Append the selected match to the current path and returns the result.
+    - `Ctrl-f`: Returns the current path.
+    - `Arrow keys`: Navigation between files.
+
+
+## Even more Productivity:
+If you're using zshell or Bash 4.3+, You can combine qfc with commands you frequently use to get one key-stroke experience. For example, I have the following lines in my .zshrc:
+```
+qfc_quick_command 'cd' '\C-b' 'cd $0'
+qfc_quick_command 'vim' '\C-p' 'vim $0'
+```
+This allows me to switch directories by just pressing Ctrl-b(or editing a file by pressing Ctrl-p).

+
+`qfc_quick_command` expects an `id`, `a shortcut`, and a command with `$0` placeholder(which will be replaced with the completion path).  
+It's recommended to choose a 2-5 length letters only `id`(else you may encounter issues).  
+Also, be careful with what keyboard shortcuts to choose(mapping some keys can prevent the terminal from working correctly).
