+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.
 
-## Installation
+## Get Started
 
-### Docker
- - `docker run -it -v $(pwd):/data -p 8080:80 klokantech/tileserver-gl`
+Make sure you have Node.js version **10** installed (running `node -v` it should output something like `v10.17.0`).
 
-### Without docker
- - Make sure you have Node v4 or higher (`nvm install 4`)
- - `npm install`
- - `node src/main.js`
+Install `tileserver-gl` with server-side raster rendering of vector tiles with npm
 
-## Sample data
-Sample data can be downloaded at https://github.com/klokantech/tileserver-gl-data/archive/master.zip
+```bash
+npm install -g tileserver-gl
+```
 
-#### Usage
-- unpack somewhere and `cd` to the directory
-- `docker run -it -v $(pwd):/data -p 8080:80 klokantech/tileserver-gl`
-  - (or `node path/to/repo/src/main.js`)
+Now download vector tiles from [OpenMapTiles](https://openmaptiles.org/downloads/).
 
-## Configuration
+```bash
+curl -o zurich_switzerland.mbtiles https://[GET-YOUR-LINK]/extracts/zurich_switzerland.mbtiles
+```
 
-Create `config.json` file in the root directory.
-The config file can contain definition of several paths where the tiles will be served.
+Start `tileserver-gl` with the downloaded vector tiles.
 
-### Example configuration file
-See https://github.com/klokantech/tileserver-gl-data/blob/master/config.json
+```bash
+tileserver-gl zurich_switzerland.mbtiles
+```
 
-**Note**: To specify local mbtiles as source of the vector tiles inside the style, use urls with `mbtiles` protocol with path relative to the `cwd + options.paths.root + options.paths.mbtiles`. (For example `mbtiles://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.
 
-## Available URLs
+## Using Docker
 
-- If you visit the server on the configured port (default 8080) you should see your maps appearing in the browser.
-- Style is served at `/styles/{id}.json` (+ array at `/styles.json`)
-  - Sprites at `/styles/{id}/sprite[@2x].{format}`
-  - Fonts at `/fonts/{fontstack}/{start}-{end}.pbf`
-- Rendered tiles are at `/styles/{id}/rendered/{z}/{x}/{y}[@2x].{format}`
-  - The optional `@2x` (or `@3x`) part can be used to render HiDPI (retina) tiles
-  - Available formats: `png`, `jpg` (`jpeg`), `webp`
-  - TileJSON at `/styles/{id}/rendered.json`
-- Static images are rendered at:
-  - `/styles/{id}/static/{lon},{lat},{zoom}[@{bearing}[,{pitch}]]/{width}x{height}[@2x].{format}` (center-based)
-  - `/styles/{id}/static/{minx},{miny},{maxx},{maxy}/{width}x{height}[@2x].{format}` (area-based)
-  - `/styles/{id}/static/auto/{width}x{height}[@2x].{format}` (autofit path -- see below)
-  - The static image endpoints additionally support following query parameters:
-    - `path` - comma-separated `lng,lat`, pipe-separated pairs
-      - e.g. `5.9,45.8|5.9,47.8|10.5,47.8|10.5,45.8|5.9,45.8`
-    - `latlng` - indicates the `path` coordinates are in `lat,lng` order rather than the usual `lng,lat`
-    - `fill` - color to use as the fill (e.g. `red`, `rgba(255,255,255,0.5)`, `#0000ff`)
-    - `stroke` - color of the path stroke
-    - `width` - width of the stroke
-    - `padding` - "percetange" padding for fitted endpoints (area-based and path autofit)
-      - value of `0.1` means "add 10% size to each side to make sure the area of interest is nicely visible"
-- Source data at `/data/{mbtiles}/{z}/{x}/{y}.{format}`
-  - TileJSON at `/data/{mbtiles}.json`
-- Array of all TileJSONs at `/index.json` (`/rendered.json`; `/data.json`)
+An alternative to npm to start the packed software easier is to install [Docker](https://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 maptiler/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.

+      "zurich-vector": {
+        "mbtiles": "zurich.mbtiles"
+      }
+    }
+  }
+
+
+``options``
+===========
+
+``paths``
+---------
+
+Defines where to look for the different types of input data.
+
+The value of ``root`` is used as prefix for all data types.
+
+``domains``
+-----------
+
+You can use this to optionally specify on what domains the rendered tiles are accessible. This can be used for basic load-balancing or to bypass browser's limit for the number of connections per domain.
+
+``frontPage``
+-----------------
+
+Path to the html (relative to ``root`` path) to use as a front page.
+
+Use ``true`` (or nothing) to serve the default TileServer GL front page with list of styles and data.
+Use ``false`` to disable the front page altogether (404).
+
+``formatQuality``
+-----------------
+
+Quality of the compression of individual image formats. [0-100]
+
+``maxScaleFactor``
+-----------
+
+Maximum scale factor to allow in raster tile and static maps requests (e.g. ``@3x`` suffix).
+Also see ``maxSize`` below.
+Default value is ``3``, maximum ``9``.
+
+``maxSize``
+-----------
+
+Maximum image side length to be allowed to be rendered (including scale factor).
+Be careful when changing this value since there are hardware limits that need to be considered.
+Default is ``2048``.
+
+``tileMargin``
+--------------
+
+Additional image side length added during tile rendering that is cropped from the delivered tile. This is useful for resolving the issue with cropped labels,
+but it does come with a performance degradation, because additional, adjacent vector tiles need to be loaded to generate a single tile.
+Default is ``0`` to disable this processing.
+
+``minRendererPoolSizes``
+------------------------
+
+Minimum amount of raster tile renderers per scale factor.
+The value is an array: the first element is the minimum amount of renderers for scale factor one, the second for scale factor two and so on.
+If the array has less elements than ``maxScaleFactor``, then the last element is used for all remaining scale factors as well.
+Selecting renderer pool sizes is a trade-off between memory use and speed.
+A reasonable value will depend on your hardware and your amount of styles and scale factors.
+If you have plenty of memory, you'll want to set this equal to ``maxRendererPoolSizes`` to avoid increased latency due to renderer destruction and recreation.
+If you need to conserve memory, you'll want something lower than ``maxRendererPoolSizes``, possibly allocating more renderers to scale factors that are more common.
+Default is ``[8, 4, 2]``.
+
+``maxRendererPoolSizes``
+------------------------
+
+Maximum amount of raster tile renderers per scale factor.
+The value and considerations are similar to ``minRendererPoolSizes`` above.
+If you have plenty of memory, try setting these equal to or slightly above your processor count, e.g. if you have four processors, try a value of ``[6]``.
+If you need to conserve memory, try lower values for scale factors that are less common.
+Default is ``[16, 8, 4]``.
+
+``serveAllStyles``
+------------------------
+
+If this option is enabled, all the styles from the ``paths.styles`` will be served. (No recursion, only ``.json`` files are used.)
+The process will also watch for changes in this directory and remove/add more styles dynamically.
+It is recommended to also use the ``serveAllFonts`` option when using this option.
+
+``watermark``
+-----------
+
+Optional string to be rendered into the raster tiles (and static maps) as watermark (bottom-left corner).
+Can be used for hard-coding attributions etc. (can also be specified per-style).
+Not used by default.
+
+``styles``
+==========
+
+Each item in this object defines one style (map). It can have the following options:
+
+* ``style`` -- name of the style json file [required]
+* ``serve_rendered`` -- whether to render the raster tiles for this style or not
+* ``serve_data`` -- whether to allow access to the original tiles, sprites and required glyphs
+* ``tilejson`` -- properties to add to the TileJSON created for the raster data
+
+  * ``format`` and ``bounds`` can be especially useful
+
+``data``
+========
+
+Each item specifies one data source which should be made accessible by the server. It has the following options:
+
+* ``mbtiles`` -- name of the mbtiles file [required]
+
+The mbtiles file does not need to be specified here unless you explicitly want to serve the raw data.
+
+Referencing local files from style JSON
+=======================================
+
+You can link various data sources from the style JSON (for example even remote TileJSONs).
+
+MBTiles
+-------
+
+To specify that you want to use local mbtiles, use to following syntax: ``mbtiles://switzerland.mbtiles``.
+The TileServer-GL will try to find the file ``switzerland.mbtiles`` in ``root`` + ``mbtiles`` path.
+
+For example::
+
+  "sources": {
+    "source1": {
+      "url": "mbtiles://switzerland.mbtiles",
+      "type": "vector"
+    }
+  }
+
+Alternatively, you can use ``mbtiles://{zurich-vector}`` to reference existing data object from the config.
+In this case, the server will look into the ``config.json`` to determine what mbtiles file to use.
+For the config above, this is equivalent to ``mbtiles://zurich.mbtiles``.
+
+Sprites
+-------
+
+If your style requires any sprites, make sure the style JSON contains proper path in the ``sprite`` property.
+
+It can be a local path (e.g. ``my-style/sprite``) or remote http(s) location (e.g. ``https://mycdn.com/my-style/sprite``). Several possible extension are added to this path, so the following files should be present:
+
+* ``sprite.json``
+* ``sprite.png``
+* ``sprite@2x.json``
+* ``sprite@2x.png``
+
+You can also use the following placeholders in the sprite path for easier use:
+
+* ``{style}`` -- gets replaced with the name of the style file (``xxx.json``)
+* ``{styleJsonFolder}`` -- gets replaced with the path to the style file
+
+Fonts (glyphs)
+--------------
+
+Similarly to the sprites, the style JSON also needs to contain proper paths to the font glyphs (in the ``glyphs`` property) and can be both local and remote.
+
+It should contain the following placeholders:
+
+* ``{fontstack}`` -- name of the font and variant
+* ``{range}`` -- range of the glyphs
+
+For example ``"glyphs": "{fontstack}/{range}.pbf"`` will instruct TileServer-GL to look for the files such as ``fonts/Open Sans/0-255.pbf`` (``fonts`` come from the ``paths`` property of the ``config.json`` example above).

+==========
+Deployment
+==========
+
+Typically - you should use nginx/lighttpd/apache on the frontend - and the tileserver-gl server is hidden behind it in production deployment.
+
+Caching
+=======
+
+There is a plenty of options you can use to create proper caching infrastructure: Varnish, CloudFlare, ...
+
+Securing
+========
+
+Nginx can be used to add protection via https, password, referrer, IP address restriction, access keys, etc.
+
+Running behind a proxy or a load-balancer
+=========================================
+
+If you need to run TileServer GL behind a proxy, make sure the proxy sends ``X-Forwarded-*`` headers to the server (most importantly ``X-Forwarded-Host`` and ``X-Forwarded-Proto``) to ensures the URLs generated inside TileJSON etc. are using the desired domain and protocol.

+===================
+Available endpoints
+===================
+
+If you visit the server on the configured port (default 8080) you can see your maps appearing in the browser.
+
+Styles
+======
+* Styles are served at ``/styles/{id}/style.json`` (+ array at ``/styles.json``)
+
+  * Sprites at ``/styles/{id}/sprite[@2x].{format}``
+  * Fonts at ``/fonts/{fontstack}/{start}-{end}.pbf``
+
+Rendered tiles
+==============
+* Rendered tiles are served at ``/styles/{id}/{z}/{x}/{y}[@2x].{format}``
+
+  * The optional ``@2x`` (or ``@3x``, ``@4x``) part can be used to render HiDPI (retina) tiles
+  * Available formats: ``png``, ``jpg`` (``jpeg``), ``webp``
+  * TileJSON at ``/styles/{id}.json``
+
+* The rendered tiles are not available in the ``tileserver-gl-light`` version.
+
+WMTS Capabilities
+==============
+* WMTS Capabilities are served at ``/styles/{id}/wmts.xml``
+
+Static images
+=============
+* Several endpoints:
+
+  * ``/styles/{id}/static/{lon},{lat},{zoom}[@{bearing}[,{pitch}]]/{width}x{height}[@2x].{format}`` (center-based)
+  * ``/styles/{id}/static/{minx},{miny},{maxx},{maxy}/{width}x{height}[@2x].{format}`` (area-based)
+  * ``/styles/{id}/static/auto/{width}x{height}[@2x].{format}`` (autofit path -- see below)
+
+* All the static image endpoints additionally support following query parameters:
+
+  * ``path`` - comma-separated ``lng,lat``, pipe-separated pairs
+
+    * e.g. ``5.9,45.8|5.9,47.8|10.5,47.8|10.5,45.8|5.9,45.8``
+
+  * ``latlng`` - indicates the ``path`` coordinates are in ``lat,lng`` order rather than the usual ``lng,lat``
+  * ``fill`` - color to use as the fill (e.g. ``red``, ``rgba(255,255,255,0.5)``, ``#0000ff``)
+  * ``stroke`` - color of the path stroke
+  * ``width`` - width of the stroke
+  * ``padding`` - "percentage" padding for fitted endpoints (area-based and path autofit)
+
+    * value of ``0.1`` means "add 10% size to each side to make sure the area of interest is nicely visible"
+
+* You can also use (experimental) ``/styles/{id}/static/raw/...`` endpoints with raw spherical mercator coordinates (EPSG:3857) instead of WGS84.
+
+* The static images are not available in the ``tileserver-gl-light`` version.
+
+Source data
+===========
+* Source data are served at ``/data/{mbtiles}/{z}/{x}/{y}.{format}``
+
+  * Format depends on the source file (usually ``png`` or ``pbf``)
+
+    * ``geojson`` is also available (useful for inspecting the tiles) in case the original format is ``pbf``
+
+  * TileJSON at ``/data/{mbtiles}.json``
+
+TileJSON arrays
+===============
+Array of all TileJSONs is at ``/index.json`` (``/rendered.json``; ``/data.json``)
+
+List of available fonts
+=======================
+Array of names of the available fonts is at ``/fonts.json``

+Installation
+============
+
+Docker
+======
+
+When running docker image, no special installation is needed -- the docker will automatically download the image if not present.
+
+Just run ``docker run --rm -it -v $(pwd):/data -p 8080:80 maptiler/tileserver-gl``.
+
+Additional options (see :doc:`/usage`) can be passed to the TileServer GL by appending them to the end of this command. You can, for example, do the following:
+
+* ``docker run ... maptiler/tileserver-gl --mbtiles my-tiles.mbtiles`` -- explicitly specify which mbtiles to use (if you have more in the folder)
+* ``docker run ... maptiler/tileserver-gl --verbose`` -- to see the default config created automatically
+
+npm
+===
+
+Just run ``npm install -g tileserver-gl``.
+
+
+Native dependencies
+-------------------
+
+There are some native dependencies that you need to make sure are installed if you plan to run the TileServer GL natively without docker.
+The precise package names you need to install may differ on various platforms.
+
+These are required on Debian 9:
+  * ``build-essential``
+  * ``libcairo2-dev``
+  * ``libprotobuf-dev``
+
+
+``tileserver-gl-light`` on 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.
+
+
+From source
+===========
+
+Make sure you have Node v10 (nvm install 10) and run::
+
+  npm install
+  node .
+
+
+On OSX
+======
+
+Make sure to have dependencies of canvas_ package installed::
+
+  brew install pkg-config cairo libpng jpeg giflib
+
+
+.. _canvas: https://www.npmjs.com/package/canvas
