+### Service creation
+
+If you'd like to add your own service, then you should follow the steps below to keep the same structure:
+
+1. Add service's Docker Compose file `services/docker-compose.YOUR_SERVICE.yml`.
+
+2. `(optional)` Add service's folder `services/YOUR_SERVICE`. For example, if you are going to store some data or configuration files only related to that service.
+
+3. `(optional)` Add service's script file `run/services/YOUR_SERVICE.sh`. For example, if you need to craete some folders in advance on `setup` step.
+
+### Service deletion
+
+If you don't need a service, you can easily delete it by running:
+
+```bash
+> bash run/sdel.sh SERVICE_NAME
+```
+
+For example, if you don't need `postgresql` service, you will run `bash run/sdel.sh postgresql` and it will delete related files.
