 # 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.
 
-## Quickstart
-Use `npm install -g tileserver-gl` to install the package from npm.
+## Get Started
 
-Then you can simply run `tileserver-gl zurich_switzerland.mbtiles` to start the server for the given mbtiles.
+Install `tileserver-gl` with server-side raster rendering of vector tiles with npm
 
-Alternatively, you can use `tileserver-gl-light` package instead, which is pure javascript (does not have any native dependencies) and can run anywhere, but does not contain rasterization features.
+```bash
+npm install -g tileserver-gl
+```
 
-Or you can use `docker run -it -v $(pwd):/data -p 8080:80 klokantech/tileserver-gl` to run the server inside a docker container.
+Now download vector tiles from [OSM2VectorTiles](http://osm2vectortiles.org/downloads/).
 
-Prepared vector tiles can be downloaded from [OSM2VectorTiles](http://osm2vectortiles.org/).
+```bash
+curl -o zurich_switzerland.mbtiles https://osm2vectortiles-downloads.os.zhdk.cloud.switch.ch/v2.0/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 -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.
