 # TileServer GL
-[![Build Status](https://travis-ci.org/klokantech/tileserver-gl.svg?branch=master)](https://travis-ci.org/klokantech/tileserver-gl)
-[![Docker Hub](https://img.shields.io/badge/docker-hub-blue.svg)](https://hub.docker.com/r/klokantech/tileserver-gl/)
 
 Vector and raster maps with GL styles. Server side rendering by Mapbox GL Native. Map tile server for Mapbox GL JS, Android, iOS, Leaflet, OpenLayers, GIS via WMTS, etc.
 
-## Get Started
+This fork adds features used by BEAT, including:
 
-Make sure you have Node.js version **6** installed (running `node -v` it should output something like `v6.11.3`).
+* Marker support in the static (rendered) maps
+* Prometheus compatible `/metrics` endpoint
+* Improved `/health/` endpoint
 
-Install `tileserver-gl` with server-side raster rendering of vector tiles with npm
-
-```bash
-npm install -g tileserver-gl
-```
-
-Now download vector tiles from [OpenMapTiles](https://openmaptiles.org/downloads/).
-
-```bash
-curl -o zurich_switzerland.mbtiles https://[GET-YOUR-LINK]/extracts/zurich_switzerland.mbtiles
-```
-
-Start `tileserver-gl` with the downloaded vector tiles.
-
-```bash
-tileserver-gl zurich_switzerland.mbtiles
-```
-
-Alternatively, you can use the `tileserver-gl-light` package instead, which is pure javascript (does not have any native dependencies) and can run anywhere, but does not contain rasterization on the server side made with MapBox GL Native.
-
-## Using Docker
-
-An alternative to npm to start the packed software easier is to install [Docker](http://www.docker.com/) on your computer and then run in the directory with the downloaded MBTiles the command:
-
-```bash
-docker run --rm -it -v $(pwd):/data -p 8080:80 klokantech/tileserver-gl
-```
-
-This will download and start a ready to use container on your computer and the maps are going to be available in webbrowser on localhost:8080.
-
-On laptop you can use [Docker Kitematic](https://kitematic.com/) and search "tileserver-gl" and run it, then drop in the 'data' folder the MBTiles.

-[![Docker Hub](https://img.shields.io/badge/docker-hub-blue.svg)](https://hub.docker.com/r/klokantech/tileserver-gl/)
-
-Vector maps with GL styles. Map tile server for Mapbox Android, iOS, GL JS, Leaflet, OpenLayers, etc. without server side rendering.
-
-## Quickstart
-Use `npm install -g tileserver-gl-light` to install the package from npm.
-
-Then you can simply run `tileserver-gl-light zurich_switzerland.mbtiles` to start the server for the given mbtiles.
-
-See also `tileserver-gl` which contains server side rendering.
-
-Prepared vector tiles can be downloaded from [OSM2VectorTiles](http://osm2vectortiles.org/).
