 # LinuxPA
-The goal is to create a fully functional PortableApps.com type launcher that can properly parse data from the PortableApps.com format. Apps are launched by a .sh file in the app's directory. Currently pulls out the Name and Category from App/AppInfo/appinfo.ini  
+LinuxPA is a try to bring a [PortableApps.com](http://portableapps.com) type launcher to Linux.  
-Works well with AppImage apps.
 
-# Why?
+# How to use
-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.  
+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 it finds. .sh script files have priority over other executable files.
 
-# Why script files?
+# Apps:
-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).
+The below place provides linux executables that don't need libs installed on the host system:  
+[AppImage](https://bintray.com/probono/AppImages)  
 
-# Why Go?
+# PortableApps.com Compatibility
-Because I like Go :) Also the way it includes all it needs into one friendly executable.
+LinuxPA works will with the PortableApps.com launcher, as it looks for apps in the PortableApps folder and grabs the app's name and icon from where it should be in the PortableApps.com format.  
+My forum at PortableApps.com can be found [here](http://portableapps.com/node/54998).  
 
-# What is needed?
+# common.sh
-Basically you need go to compile the source, AND YOU ALSO NEED TO MOUNT YOUR FLASH DRIVE SO YOU CAN EXECUTE FILES ON IT!!!! I've found that the mount arguments of `exec,noauto,nodev,nosuid,umask=0000` works well (I personally put my flash drive into /etc/fstab).
+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  
 
-# Format
+# Simple App Setup
-The first place the program looks for an app's icon and info is in the /App/AppInfo directory (icon defaults to appicon_32.png, otherwise it just picks the last one it finds), but if it can't find the appinfo.ini or app icon, it looks in the apps root directory for appinfo.ini and appicon.png for info and icon respectively(Just to make it easier for custom settings in an app).
+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.  
 
-# TODO
+# AppImage Support
-Add in a common.sh that is executed with each script. (Allows for setting environment variables such as HOME)  
+[AppImage Website](http://appimage.org)  
-MAKE IT BETTER  
+Right now AppImages are simply supported via the native linux executable support, and you can download AppImages. (Woo)
-Add an open button (I know, I just wanted to get the initial working before making it user friendly)  
+
-Check if all apps are closed when it closes and ask if you want to force stop the apps.  
+# USB mount
-(Maybe)Create an installer.
+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`  
+
+# Screenshots
+Photos are found [Here](https://goo.gl/photos/VtBUL6DyZTMidj5n6). The screenshots are with the adapta gtk theme
+
+# TODO (Might be in order)
+1. MAKE IT BETTER  
+1. Manual update check   
+1. Better AppImage integrations (Specifically updating, getting information from the appimage, and better appimage downloading)
+1. Automagic appimage updating (It will of course ask you beforehand)
+1. Get information (such as name and icon) directly from an appimage
+1. Better appimage downloading (probably based around [AppImageHub](https://appimage.github.io/apps/))
+1. Sandboxing support  
+1. Check if all apps are closed when it closes and ask if you want to force stop the apps
