-
-    1. Create the file *Caddyfile*
-
-        ```sh
-        touch Caddyfile
-        chown 1000 Caddyfile
-        # chown 1000 because caddy-scratch runs as user ID 1000 by default
-        chmod 600 Caddyfile
-        ```
-
-        with this content:
-
-        ```ruby
-        :8000 {
-            proxy / xyz:8000
-        }
-        :9000 {
-            proxy / abc:9000
-        }
-        ```
-
-        You can of course make more complicated Caddyfile (such as proxying `/xyz` to xyz:8000 and `/abc` to abc:9000, just ask me!)
-
-    1. Run Caddy with
-
-        ```sh
-        docker run -d -p 8000:8000/tcp -p 9000:9000/tcp \
-        --link pia:xyz --link pia:abc \
-        -v $(pwd)/Caddyfile:/Caddyfile:ro \
-        qmcgaw/caddy-scratch
-        ```
-
-        **WARNING**: Make sure the Docker network in which Caddy runs is the same as the one of PIA. It can be the default `bridge` network.
-
-    1. You can now access xyz:8000 at [localhost:8000](http://localhost:8000) and abc:9000 at [localhost:9000](http://localhost:9000)
-
-    For more containers, add more `--link pia:xxx` and modify the *Caddyfile* accordingly
-
-    If you want to user a *docker-compose.yml*, you can use this example - **make sure PIA is launched and connected first**:
-
-    ```yml
-    version: '3'
-    services:
-      piaproxy:
-        image: qmcgaw/caddy-scratch
-        container_name: piaproxy
-        ports:
-          - 8000:8000/tcp
-          - 9000:9000/tcp
-        external_links:
-          - pia:xyz
-          - pia:abc
-        volumes:
-          - ./Caddyfile:/Caddyfile:ro
-      abc:
-        image: abc
-        container_name: abc
-        network_mode: "container:pia"
-      xyz:
-        image: xyz
-        container_name: xyz
-        network_mode: "container:pia"
-    ```
