+## Environment
+
+### Postgres Database
+
+The database login-details are set upon first-launch.
+Therefore trying to change them later, after first-launch, will require a change of these details.
+A way of sidestepping manually changing this in the DB-shell is by deleting the postgres data volume.
+
+> [!WARNING]
+> Do not run this command in prod, it will delete ALL data in our database.
+
+```shell
+docker volume rm quatsh-website_postgres-data
+```
+
+After running this command a Django Migration has to be run to remake the tables.
+
+``` shell
+docker exec quatsh-website-web-1 python manage.py migrate
+```
