-Killswitch immediately stops the server.
-
-### Warning
-This terminates the server process, meaning it's like you'd pull the power. \
-So you will lose some progress (since the last auto save), or worst case your world (or other data) gets corrupted.
-
-Terminal froze after kill? `reset`
-
-### Over a command
-No key is required. \
-`/servkill` is the command. Permission: `tweaks724.servkill`. \
-You must grant the permission manually, like with a permission plugin - it's not automatically assigned even to OPs.
-
-### Over HTTP
-HTTP is insecure, meaning others *could* intercept your request to the server and get your key. \
-To encrypt, put this behind a proxy to get HTTPS or a VPN (directly to the server, not a commercial VPN) \
-Or regenerate the key after every usage.
-
-Make a GET request to `/key/<base64 encoded key>`
-
-Example:
-```
-https://127.0.0.1:57932/key/lNwANMSZhLiTWhNxSoqQ5Q==
-|_   server address   _|   |_ base64 encoded key _|
-```
-
-The response is a 404 no matter what. Either way, you will notice that the server has stopped.
-
-The key is generated to `plugins/Tweaks724/storage/killswitch key` \
-To use it with HTTP server, encode it to base64.
-
-Rate limit is 1 request / 5 minutes
