+## 0️ Prepare your machine
+
+A server with a recent version of [docker](https://www.docker.com/) is required.
+
+## 1️ Run docker image
+
+The command to use is similar to the following:
+```shell
+docker run --env INPUT_TOKEN=**** --env INPUT_USER=user --volume=/tmp:/metrics_renders ghcr.io/lowlighter/metrics:latest
+```
+
+To pass parameters, pass environment variable with the same name as the corresponding action option but in uppercase and prefixed with `INPUT_`.
