+
+## Package Saver what is it ?
+
+It's a tools to save the package you want to keep for your reinstallation. They are all in a txt file, just need paste them after your reinstallation to have it back
+
+## What is automated ?
+
+Currently the only automed thing is the detection and the parsing of your package manager (for the moment only pacman and apk are parsed and working). Later I will work on a GUI and a way to just use this programs to reinstall package from a list of packages.
+
+## How to use it ?
+
+1) Make sure you have the correct permission to use it
+
+> chmod 777 packageManager.sh
+
+2) Just run it and say yes or no if you want to keep this package (by default it's no so just need to write Y or y if you want to keep it)
+
+> ./packageManager.sh
+
