-OpenFusion is a reverse-engineered server for FusionFall. It primarily targets versions `beta-20100104` and `beta-20111013` of the original game, with [limited support](https://github.com/OpenFusionProject/OpenFusion/wiki/FusionFall-Version-Support) for others.

 ## Usage
 
 ### Getting Started
 #### Method A: Installer (Easiest)
-1. Download the client installer by clicking [here](https://github.com/OpenFusionProject/OpenFusion/releases/download/1.5.2/OpenFusionClient-1.5.2-Installer.exe) - choose to run the file.
+1. Download the client installer by clicking [here](https://github.com/OpenFusionProject/OpenFusion/releases/download/1.6/OpenFusionClient-1.6-Installer.exe) - choose to run the file.
 2. After a few moments, the client should open: you will be given a choice between two public servers by default. Select the one you wish to play and click connect.
 3. To create an account, simply enter the details you wish to use at the login screen then click Log In. Do *not* click register, as this will just lead to a blank screen.
 4. Make a new character, and enjoy the game! Your progress will be saved automatically, and you can resume playing by entering the login details you used in step 3.
 
 #### Method B: Standalone .zip file
-1. Download the client from [here](https://github.com/OpenFusionProject/OpenFusion/releases/download/1.5.2/OpenFusionClient-1.5.2.zip).
+1. Download the client from [here](https://github.com/OpenFusionProject/OpenFusion/releases/download/1.6/OpenFusionClient-1.6.zip).
 2. Extract it to a folder of your choice. Note: if you are upgrading from an older version, it is preferable to start with a fresh folder rather than overwriting a previous install.
 3. Run OpenFusionClient.exe - you will be given a choice between two public servers by default. Select the one you wish to play and click connect.
 4. To create an account, simply enter the details you wish to use at the login screen then click Log In. Do *not* click register, as this will just lead to a blank screen.

 ### Hosting a server
-1. Grab `OpenFusionServer-1.5-Original.zip` or `OpenFusionServer-1.5-Academy.zip` from [here](https://github.com/OpenFusionProject/OpenFusion/releases/tag/1.5.2).
+1. Grab `OpenFusionServer-1.6-Original.zip` or `OpenFusionServer-1.6-Academy.zip` from [here](https://github.com/OpenFusionProject/OpenFusion/releases/tag/1.6).
 2. Extract it to a folder of your choice, then run `winfusion.exe` (Windows) or `fusion` (Linux) to start the server.
 3. Add a new server to the client's list:
     1. For Description, enter anything you want. This is what will show up in the server list.

 ## Compiling 
 
-OpenFusion has one external dependency: SQLite. The oldest compatible version is `3.33.0`. You can install it on Windows using `vcpkg`, and on Unix/Linux using your distribution's package manager. For a more indepth guide on how to set up vcpkg, [read this guide on the wiki](https://github.com/OpenFusionProject/OpenFusion/wiki/Installing-SQLite-on-Windows-using-vcpkg).

 You have two choices for compiling OpenFusion: the included Makefile and the included CMakeLists file.
 
 ### Makefile
 
-A detailed compilation guide is available for Windows users in the wiki [using MinGW-w64 and MSYS2](https://github.com/OpenFusionProject/OpenFusion/wiki/Compilation-on-Windows). Otherwise, to compile it for the current platform you're on, just run `make` with the correct build tools installed (currently make and clang).
