+The default misskey docker install guide will place misskey code and your instance data in the same directory. Is something goes wrong on a later time, you may accidentally trash your datas (docker volumes mounted for the postgres database, redis cache...).
+
+Separate the misskey code (git clone...) from you container's volumes, something like this should do:
+```
+/usr/local/misskey/code
+/usr/local/misskey/data
+```
+
+You will need a custom yaml file for docker-compose, but it's worth it (see sample yaml file).
+
+Manage your misskey instance containers with docker-compose and the right path for code and datas:
+```
+docker-compose --project-directory=/usr/local/misskey/data -f /usr/local/misskey/data/<your custom docker-compose>.yml 
+```
