Forgot to up version number

Minor updates due to new library versions
Added go.mod to use Go's versioning system.

 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, but if one isn't found it launches the first executable in general.
+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.
+
+# Apps:
+The below place provides linux executables that don't need libs installed on the host system:  
+[https://appimage.github.io/](https://appimage.github.io/)  
 
 # PortableApps.com Compatibility
 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).  
 
 # common.sh
-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).  
+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
-[AppImage Website](http://appimage.org)  
-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.  
+[AppImage Website](http://appimage.org)
+I'm looking into improving AppImage support. As of 2.1.5.0 IF `unsquashfs` is in $PATH then some advanced AppImage support is available and it will automagically get the name and possibly the icon of it. I'm looking into better support, but it might be a while.
 
 # USB mount
-Unfortunately Linux, by default, doesn't support running executables off of flash drives, requiring you to mount your drive with special mount arguments, I personally use the arguments `exec,noauto,nodev,nosuid,umask=0000`  
+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`

 # TODO (Might be in order)
-1. MAKE IT BETTER  
-1. Add settings menu  
-1. Add updater for .AppImage files  
-1. Download .AppImage files (maybe)  
-1. Check if all apps are closed when it closes and ask if you want to force stop the apps.  
-1. Portable wine???  
+1. MAKE IT BETTER  
+1. Try to `chmod +x` executables if they don't have the permission
+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
