+# Some docker bacics and some info
+
+You **do not** need to fuck with `docker-compose.yml` to get something up,
+simple copy paste should suffice.
+
+You **do need** to fuck with `.env` file, that's where all your variables are.
+  
+Also sometimes the `.env` file is used as `env_file`
+
+* `.env` - name of the file used only by compose.</br>
+  It is used automaticly just by being in the directory
+  with the `docker-compose.yml`</br>
+  Variables set there are only available during the building of the container.
+* `env_file` - an option in compose that defines existing external file.</br>
+  Variables set in this file will be available in the running container,
+  but not in compose.
+
+So to not have polluted huge ass compose file, or to not have multiple places
+where changes need to be made...  `env_file: .env` BAM.
+
+Only issue is that all variables are avaialble in all containers.</br>
+So that can lead to potential conflicts and clashes, looking at you nextcloud.
+
+In those cases variables names to be used are declared per container.
+
+But it is just so much easier, pretier to `env_file: .env`, and mostly painless.
