  ### Getting Started
  +#### Method A: Installer (Easiest)
  +1. Download the client installer by clicking [here](https://github.com/OpenFusionProject/OpenFusion/releases/download/1.4/OpenFusionClient-1.4-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/1.4/OpenFusionClient-1.4.zip).

  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.
