+# OSX Packages Uninstaller
+
+This software is aimed to help manage packages uninstalling in OSX.
+
+## Installation
+
+Installation is as simple as:
+
+ [sudo] bash < <(curl -sL https://raw.github.com/mpapis/pkg_uninstaller/master/pkg-installer)
+
+Adding to PATH, for system installation (with sudo):
+
+ echo 'PATH=$PATH:/opt/pkg_uninstaller' >> /etc/profile
+
+Adding PATH when installed as user (without sudo):
+
+ echo 'PATH=$PATH:$HOME/.pkg_uninstaller' >> $HOME/.bash_profile
+
+Note the single quotes are important in both cases.
+
+## Installing package file
+
+Install packages with:
+
+ pkg-install <package_file.pkg>
+
+This will create `uninstall_<package_file_pkg>.sh` in current directory.
+
+To uninstall this package just execute `./uninstall_<package_file_pkg>.sh`.
+
+### Example
+
+ # coming soon
+
+## Uninstalling single packages by name.
+
+List available package names (possibly filtering by [name]):
+
+ pkg-list [name]
+
+Uninstall package:
+
+ pkg-uninstall <name>
+
+## Using internally in package to build uninstaller
+
+1. You have to bundle `pkg-wrapper` with your application 
+and install it to disk before executing the hook bellow.
+
+1. In before installing hook call this script:
+
+ #!/bin/bash
+
+ pkg-wrapper before "your package name"
+
+1. In after installing hook call this script:
+
+ #!/bin/bash
+
+ pkg-wrapper before "your package name" /path/to/uninstaller_name.sh
+
+1. In uninstall hook call:
+
+ #!/bin/bash
+
+ /path/to/uninstaller_name.sh
+ rm /path/to/uninstaller_name.sh
