+# Japari Bypass
+Efficient KF3/DMM game launcher.
+
+## Requirements
+Python 3 and pip.
+
+KF3 installed from DMM. DMM itself does not need to be running.
+
+## Instructions
+Download the files from this repo. Unzip them to a safe place.
+
+Run `run_KF3.bat`, it will ask you for some information.
+
+It will ask for the location of the KF3 executable. Generally this will be `C:\users\[your name]\KFP2G\けもフレ３.exe`.
+
+Input your DMM email and then password when prompted, and `yes` if you want to use the public VPN to connect to DMM's server. If you choose not to use the public VPN, then you will need to enable your own Japanese VPN while logging in to the game.
+
+If you make a mistake or you want to change login details, edit the `kfp2g.cfg` config file, or delete it to run the configuration again.
+
+If KF3 needs to update, use `update_and_run_KF3.bat` and it will install any new updates.
+
+## Known issues
+Retrieving launch arguments - error 308: Every once in a while, DMM games may have updated terms of service that need to be accepted. This can only be done via the official DMM app.
