+## `config.yaml` example
+
+Put this `config.yaml` in `/etc/OliveTin/` if you're running a standard service, or mount it at `/config` if running in a container.
+
+```yaml
+listenAddressWebUI: 0.0.0.0:1337 # Listen on all addresses available, port 1337
 logLevel: "INFO"
+actions: 
+- title: Restart Plex
+  icon: smile

+  shell: ping google.com -c 1

-## Building the container 
+## Ports 
 
-### Podman/Docker
+By default OliveTin will use the following ports;
+
+* `1337` - for hosting the web interface
+* `1338` - for the REST API (the api the web interface uses to do stuff)
+* `1339` - a modern gRPC API (OliveTin uses protobuf under the hood) 
+
+Some people might not want the gRPC API public - simply set `listenAddressGrpcActions: 127.0.0.1:1339` in your config so it doesn't listen publicly. It cannot be disabled completely - it's required for the REST API to work though.
+
+## Installation - systemd service (recommended)
+
+Running OliveTin as a systemd service on a Linux machine is a bit more effort than running as a container - but it means it can use any program installed on your machine (you don't have to add programs to a container). 
+
+1. Copy the `OliveTin` binary to `/usr/sbin/OliveTin`
+2. Copy the `webui` directory contents to `/var/www/olivetin/` (eg, `/var/www/olivetin/index.html`)
+3. Copy the `OliveTin.service` file to `/etc/systemd/system/`
+4. Create a `config.yaml` using the example provided above to get you started.
+
+Run `systemctl restart OliveTin` and check `systemctl status OliveTin`.
+
+## Installation - as a container 
+
+Of course, running a container image is very straightforward - but you might need to add files and programs to the OliveTin container to make it useful for your use case. Generally running a systemd service is better for OliveTin. 
+
+### Running - `podman` (or `docker`)
 
 ```
-podman create --name olivetin -p 1337 -p 1338 -p 1339 -v /etc/olivetin/:/config:ro olivetin
+root@host: podman create --name olivetin -p 1337 -p 1338 -p 1339 -v /etc/olivetin/:/config:ro olivetin
 
 ```
 
-### Buildah/Docker
+### Building - `buildah` (or `docker build`)
 
 ```
-buildah bud -t olivetin
