+
+**Run Google's Lighthouse headless in the background**
+
+This image allows you to quickly run [lighthouse](https://github.com/GoogleChrome/lighthouse) in a headless container. That's useful if you want to run it from a CI server, or in the background of your workstation.
+
+To install:
+
+```shell
+    git clone git@github.com:MatthiasWinkelmann/lighthouse-chromium-alpine-docker.git
+    docker build -t lighthouse-chromium-alpine-docker
+```
+
+Processes within the container cannot easily access the host's file system. You can either print to STDOUT and redirect to a file, or mount a local folder in the container, as shown here:
+
+```shell
+ run -v  ./output/:/lighthouse/output/ lighthouse-chromium-alpine-docker --output-path=/lighthouse/output/results.html --save-assets --save-artifacts --output=html https://google.com
+```
