-Readme and program are WIP. It is currently still in the early alpha stages, meaning bugs and unimplemented code paths can be found on the master branch.
+## About
+
+Despite many popular online games adding rich presence support to Discrd, Path of
+Exile has not. This is a third party tool that scans the game's log file and displays
+game events on your Discord profile.
+
+## Usage
+
+Download the application from [releases](https://github.com/siegrest/Exiled-Presence/releases). It should work out-of-the-box.
+
+Upon running the executable it will start searching for the game process. 
+Once found, it will attempt to parse the game's log file. Note that if the log file
+is over 10MB in size this can be extremely slow and resource consuming (you will get 
+a warning message if this is the case).
+
+To have it display information about your character one of two things are required.
+First, right click the tray icon and open up the "menu". Navigate to the `config`
+tab and input your account name so the program can get the character you're playing.
+If your profile is set to private, the POESESSID is requird as well. The instructions
+on how to find your POESESSID can be found in the correct menu or simply by googling.
+
+All config option will be saved and automatically loaded the next time you run the 
+application.
+
+Navigate back to the main menu and stop and restart the service. After this you can
+input `X` to hide the console, the service will remain running in the tray.
+
+Load up the game and log in, you should see your Discord presence update momentarily.
