 # Why?
 I know that Linux only has about 2% desktop usage and I know that the traditional way to install apps isn't portable, but over the past year or so I've started to put linux apps on my flash drive (AppImage is a great example of a portable solution to linux apps. Also a lot of DRM-free games can be run portably), but there was no easy way to organize my linux apps, so I created one. I personally have used the PortableApps.com launcher for years now and I love how properly formated the apps are, which allows me to grab info about the app easily.  

-# Why script files?
-In general linux executable files have no extensions and can be a pain when trying to figure out what is executable and what isn't. I figured script files are easy to detect and allow a large amount of flexibility for me (and others who want to make apps work with this launcher). See below for .AppImage support (Get AppImages from [here](https://bintray.com/probono/AppImages))

 # Why Go?
 Because I like Go :) Also the way it includes all it needs into one friendly executable.

 # common.sh
 common.sh is run before any program so you can set environment variables (such as HOME). common.sh should be in PortableApps/LinuxPACom folder. Paths should be made relitive to where LinuxPA is.

-# AppImage support
-It will now launch .AppImage files! If a .sh script and an .AppImage executable are both in a directory, the .sh script takes precedence. You can get AppImages from [here](https://bintray.com/probono/AppImages).
+# Executable search
+For a given app, it tried to look for script files (looks for the file to start with `#!`) and then looks for standard executable files (looks for the file to start with `ELF`)

 # TODO (Might be in order)
-1. MAKE IT BETTER  
-1. Improve linux executable detection (A.K.A. a pain in the butt) (I'm currently thinking of checking each file to see if the file starts out with #! or ELF)  
+1. MAKE IT BETTER   
 1. Launching of .exe files via wine (wine will have to be installed on the host system, unless there is some portable wine, I may have found one)  
 1. Add settings menu  
 1. Add updater for .AppImage files
