 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:
+## Installation
+
+### From Github
+
+Github URL: <https://github.com/MatthiasWinkelmann/lighthouse-chromium-alpine-docker>
 
 ```shell
     git clone [email protected]:MatthiasWinkelmann/lighthouse-chromium-alpine-docker.git
-    docker build -t lighthouse-chromium-alpine-docker
+    docker build -t lighthouse lighthouse-chromium-alpine-docker
+```
+
+### From Docker Hub
+
+Docker Hub URL: <https://hub.docker.com/r/matthiaswinkelmann/lighthouse-chromium-alpine/>
+
+```shell
+docker pull matthiaswinkelmann/lighthouse-chromium-alpine
 ```
 
+## Usage
+
 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:
 
+### Quickstart: Print to STDOUT
+
 ```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
+docker run lighthouse --output-path=stdout https://google.com
 ```
 
-Run the tesT:
+### Saving to file
 
 ```shell
-docker run -it --rm --entrypoint=sh lighthouse test.sh
+docker run -v ./output/:/lighthouse/output/ lighthouse --output-path=/lighthouse/output/results.html --save-assets --save-artifacts https://google.com
 ```
+
+## Testing
+
+```shell
+docker run lighthouse
+```
