+# node-webserver
 
 Provides a minimal webserver (via Express.js) to expose static files from the Docker host via HTTP.
 This image is build on Alpine Linux (base image `alpine:node`) and aims for a minimal size.
 
-Usage
-=====
+## Usage
 
 You can expose a local directory which you want to have served via the `mini-webserver` by starting it with
 
 `docker run --name node-web -p 8080:8080 -v $PWD/test:/app/public:ro -d netresearch/node-webserver`
 
 In this example, the port on the docker host where the `node-webserver` is reachable is `8080`.

+### Logging
 
 The Express.js app uses `morgan` to pipe the web logs to the `STDOUT`. This means that the logs are visible via
 `docker logs node-web` (if the container name is `node-web`).
