How to do a complete uninstall of appwrite to start fresh ?

I would like to do a complete uninstall of appwrite including project data, databases etc. to have a fresh start in my prototype environment.

I am aware of https://appwrite.io/docs/self-hosting#uninstall but is there any other data on my filesystem/machine i need to remove manually ?

You might want to purge local appwrite and its other containers from docker.

nope, that's all you need to do. Appwrite uses docker which stores data in volumes. the -v flag wipes the volumes
