+## Image Usage
+
+The preferred way to start WireGuard Portal as Docker container is to use Docker Compose.
+
+A sample docker-compose.yml:
+
+```yaml
+version: '3.6'
+services:
+  wg-portal:
+    image: wgportal/wg-portal:v2
+    restart: unless-stopped
+    cap_add:
+      - NET_ADMIN
+    network_mode: "host"
+    ports:
+      - "8888:8888"
+    volumes:
+      - /etc/wireguard:/etc/wireguard
+      - ./data:/app/data
+      - ./config:/app/config
+```
+
+By default, the webserver is listening on port **8888**.
+
+Volumes for `/app/data` and `/app/config` should be used ensure data persistence across container restarts.
+
+## Image Versioning
+
+All images are hosted on Docker Hub at [https://hub.docker.com/r/wgportal/wg-portal](https://hub.docker.com/r/wgportal/wg-portal).
+There are three types of tags in the repository:
+
+#### Semantic versioned tags
+For example, `1.0.19`.
+
+These are official releases of WireGuard Portal. They correspond to the GitHub tags that we make, and you can see the release notes for them here: [https://github.com/h44z/wg-portal/releases](https://github.com/h44z/wg-portal/releases).
+
+Once these tags show up in this repository, they will never change.
+
+For production deployments of WireGuard Portal, we strongly recommend using one of these tags, e.g. **wgportal/wg-portal:1.0.19**, instead of the latest or canary tags.
+
+If you only want to stay at the same major or major+minor version, use either `v[MAJOR]` or `[MAJOR].[MINOR]` tags. For example `v1` or `1.0`.
+
+Version **1** is currently **stable**, version **2** is in **development**.
+
+#### latest
+This is the most recent build to master! It changes a lot and is very unstable.
+
+We recommend that you don't use it except for development purposes.
+
+#### Branch tags
+For each commit in the master and the stable branch, a corresponding Docker image is build. These images use the `master` or `stable` tags.
+
+
+
+## Configuration
+You can configure WireGuard Portal using a yaml configuration file.
+The filepath of the yaml configuration file defaults to `/app/config/config.yml`.
+It is possible to override the configuration filepath using the environment variable **WG_PORTAL_CONFIG**.
+
+By default, WireGuard Portal uses a SQLite database. The database is stored in `/app/data/sqlite.db`.
+
+You should mount those directories as a volume:
+- /app/data
+- /app/config
+
+### Configuration Options
+All available YAML configuration options are available [here](https://github.com/h44z/wg-portal#configuration).
+
+A very basic example:
+
+```yaml
+core:
+  admin_user: test@wg-portal.local
+  admin_password: secret
+
+web:
+  external_url: http://localhost:8888
+  request_logging: true
+```
