 # proxy
+
 This proxy is based on NGINX. The NGINX configuration is generated by a simple Node.js script which parses
 the docker socket. NGINX acts as a reverse proxy server. The Node.js script reads the docker socket file to generate
 a configuration for each running docker container. The base template for configuration is `nginx.conf.template`
@@ -6,42 +7,50 @@ All `*.template` files are written with [mustache-js](https://github.com/janl/mu
 The templates are assembled by the Node.js program.
 
 ## Docker Mapping
+
 The Node.js script reads out the `/var/run/docker.sock` to get the containers of the host system via
 [dockerode](https://github.com/apocas/dockerode "GitHub").
 
 **Important:**
 The proxy expects your backend containers to provide following structure:
+
 * `stapps.version`-label of docker container to be set to a valid active version. See configuration....
-* Service name for the backend container should be `backend` in docker-compose.yml. If you don't use docker-compose 
+* Service name for the backend container should be `backend` in docker-compose.yml. If you don't use docker-compose
 set `com.docker.compose.service`-label to `backend`.
 * The proxy container to run with `--net="host"`
 * A port exposed to the host machine. If you want to expose it only to the host machines internal loopback use following
+
 syntax: `127.0.0.1:3000-3500:3000` in docker-compose or docker ports configuration. This will attach the internal 3000
 port to the host's loopback on any port between 3000-3500. The proxy will see in the docker.sock which
 port and ip was chosen. Internal loopback should be 127.0.0.1 tho.
 
 ## Configuration (Status Codes)
+
 Config files can be added by multiple universities (adding files like `config/default-b-tu`) and selected via the
 `NODE_APP_INSTANCE` environment variable.
 
-- OutdatedVersions return a `HTTP 404`
-- ActiveVersions return a `HTTP 503` if currently unavailable or the given code by running backend-node
-- Unsupported versions (not configured as outdated or active) return a `HTTP 404`
-- No version header given returns a `HTTP 300`

 **NOTE:** The default configuration expects the client to set a version header: `X-StApps-Version=<version of app>`
 
 ## Logger
-The proxy uses [@stapps/logger](https://gitlab.tubit.tu-berlin.de/stapps/logger). You can provide `NODE_ENV=production` 
-and SMTP-Configuration via environment-variables for monitoring in production use.
