 # Uncaught Script Errors 
 I’ve done my best to catch any possible errors that might pop up and write functionality to handle them. But If an error happens that i haven't written resolves for, it will pop up a message box that looks like this. Please send me a screenshot so I can write a patch for the bug.

+1. [Install Autohotkey v1](https://www.autohotkey.com/download/)
+2. `git clone` the project and then either run the `Compile Uploader to EXE.ahk` autohotkey script to compile automatically, or start up the AHK compiler that comes installed with Autohotkey and select the `Freedomain Social Media Poster.ahk` and `\Assets\FreedomainSMP.ico` icon.
