 LinuxPA is a try to bring a [PortableApps.com](http://portableapps.com) type launcher to Linux.  
 
 # How to use
-Just double click on an app to launch it! If there are multiple executables, you can either select the specific executable, or if you just double click the app it'll launch the first linux executable (.sh script files have priority), but if one isn't found it launches the first executable in general.

+common.sh is found in the PortableApps/LinuxPACom folder and is executed before the app. I mainly use it to set environment variables (such as HOME). You can create and edit the common.sh from settings  
 
 # Simple App Setup
-Because apps aren't natively formated in the PortableApps.com format, if LinuxPA doesn't find the AppInfo.ini or appicon_\*.png in the App/AppInfo folder of the app it looks for them in the root directory of the app (except it looks, nor for appicon_\*.png, but appicon.png). If an AppInfo.ini file isn't found then the name of the app is grabbed from the folder name and it's category is set to other. It specifically looks for the lines starting with `Name=` and `Category=`  
+Because apps aren't natively formated in the PortableApps.com format, LinuxPA will look in the root directory for a AppInfo.ini (for basic info such as category and name) and appicon.png. If they aren't found, it looks where the appicon_\*.png and AppInfo.ini is in PortableApps format. You can set what the AppInfo.ini and appicon.png are from LinuxPA.  
 
 # AppImage Support

-Right now AppImages are simply supported via the native linux executable support, but later I'm hoping to add downloading and automatic updating support later on.  
+Right now AppImages are simply supported via the native linux executable support, and you can download AppImages. (Woo)
 
 # USB mount
 Unfortunately Linux, by default, doesn't support running executables off of FAT formated flash drives, requiring you to mount your drive with special mount arguments or format in a linux friendly format (such as EXT4). I personally use the arguments `exec,noauto,nodev,nosuid,umask=0000`
