 # 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/)
+[![GitHub Workflow Status](https://img.shields.io/github/actions/workflow/status/maptiler/tileserver-gl/pipeline.yml)](https://github.com/maptiler/tileserver-gl/actions/workflows/pipeline.yml)

+
+Vector and raster maps with GL styles. Server-side rendering by MapLibre GL Native. Map tile server for MapLibre GL JS, Android, iOS, Leaflet, OpenLayers, GIS via WMTS, etc.
+
+Download vector tiles from [OpenMapTiles](https://data.maptiler.com/downloads/planet/).
+## Getting Started with Node
+
+Make sure you have Node.js version **14.20.0** or above installed. Node 18 is recommended. (running `node -v` it should output something like `v18.x.x`). Running without docker requires [Native dependencies](https://maptiler-tileserver.readthedocs.io/en/latest/installation.html#npm) to be installed first.
+
+Install `tileserver-gl` with server-side raster rendering of vector tiles with npm. 
+
+```bash
+npm install -g tileserver-gl
+```
+
+Once installed, you can use it like the following examples.
+
+using a mbtiles file
+```bash
+wget https://github.com/maptiler/tileserver-gl/releases/download/v1.3.0/zurich_switzerland.mbtiles
+tileserver-gl --mbtiles zurich_switzerland.mbtiles
+[in your browser, visit http://[server ip]:8080]
+```
+
+using a config.json + style + mbtiles file
+```bash
+wget https://github.com/maptiler/tileserver-gl/releases/download/v1.3.0/test_data.zip
+unzip test_data.zip
+tileserver-gl
+[in your browser, visit http://[server ip]:8080]
+```
+
+Alternatively, you can use the `tileserver-gl-light` npm 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 Maplibre GL Native.
+
+## Getting Started with Docker
+
+An alternative to npm to start the packed software easier is to install [Docker](https://www.docker.com/) on your computer and then run from the tileserver-gl directory
+
+Example using a mbtiles file
+```bash
+wget https://github.com/maptiler/tileserver-gl/releases/download/v1.3.0/zurich_switzerland.mbtiles
+docker run --rm -it -v $(pwd):/data -p 8080:8080 maptiler/tileserver-gl --mbtiles zurich_switzerland.mbtiles
+[in your browser, visit http://[server ip]:8080]
+```
+
+Example using a config.json + style + mbtiles file
+```bash
+wget https://github.com/maptiler/tileserver-gl/releases/download/v1.3.0/test_data.zip
+unzip test_data.zip
+docker run --rm -it -v $(pwd):/data -p 8080:8080 maptiler/tileserver-gl
+[in your browser, visit http://[server ip]:8080]
+```
+
+Example using a different path
+```bash
+docker run --rm -it -v /your/local/config/path:/data -p 8080:8080 maptiler/tileserver-gl
+```
+replace '/your/local/config/path' with the path to your config file
 
 
-## Installation
+Alternatively, you can use the `maptiler/tileserver-gl-light` docker image 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 Maplibre GL Native.
 
-### Docker
- - `docker run -it -v $(pwd):/data -p 8080:80 klokantech/tileserver-gl`
+## Getting Started with Linux cli
 
-### Without docker
- - Make sure you have Node v4 or higher (`nvm install 4`)
- - `npm install`
- - `node src/main.js`
+Test from command line
+```bash
+wget https://github.com/maptiler/tileserver-gl/releases/download/v1.3.0/test_data.zip
+unzip -q test_data.zip -d test_data
+xvfb-run --server-args="-screen 0 1024x768x24" npm test
+```
 
-## Sample data
-Sample data can be downloaded at https://github.com/klokantech/tileserver-gl-data/archive/master.zip
+Run from command line
+```bash
+xvfb-run --server-args="-screen 0 1024x768x24" node .
+```
 
-#### 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`)
+## Documentation
 
-## Configuration
+You can read the full documentation of this project at https://maptiler-tileserver.readthedocs.io/.
 
-Create `config.json` file in the root directory.
-The config file can contain definition of several paths where the tiles will be served.
+## Alternative
 
-### Example configuration file
-See https://github.com/klokantech/tileserver-gl-data/blob/master/config.json
+Discover MapTiler Server if you need a [map server with easy setup and user-friendly interface](https://www.maptiler.com/server/).
 
-**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`)
-
-## Available URLs
-
-- 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`)

+      "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.
+
+``allowRemoteMarkerIcons``
+--------------
+
+Allows the rendering of marker icons fetched via http(s) hyperlinks.
+For security reasons only allow this if you can control the origins from where the markers are fetched!
+Default is to disallow fetching of icons from remote sources.
+
+``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 or apache on the frontend. 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, ...
+
+Cloudflare Cache Rules
+-----------
+
+Cloudflare supports custom rules for configuring caching:
+https://developers.cloudflare.com/cache/about/cache-rules/
+
+tileserver-gl renders tiles in multiple formats - ``.png``, ``.jpg (jpeg)``, ``.webp`` for the raster endpoints, ``.pbf`` for vector endpoint. In addition, style information is generated with ``.json`` format.
+
+Endpoint data can be configured to be cached by Cloudflare. For example to cache vector endpoint you will need to configure Cloudflare rules for the ``.pbf`` and ``.json`` data.
+
+Create a rule which matches ``hostname (equal)`` and ``URI Path (ends with)`` for ``.pbf`` and ``.json`` fields. Set cache status to eligible for cache to enable the caching and overwrite the ``Edge TTL`` with ``Browser TTL`` to be 7 days (depends on your application usage).
+
+This will ensure that your tiles are cached on the client side and by Cloudflare for seven days. If the tileserver is down or user has no internet access it will try to use cached tiles.
+
+Note that ``Browser TTL`` will overwrite expiration dates on the client device. If you rebuild your maps, old tiles will be rendered until it expires or cache is cleared on the client device.
+
+Nginx Cache
+-----------
+
+If you have a reverse proxy setup in front of the tileserver you may want to enable caching as it will greatly offload requests from the application.
+
+Configure the proxy cache path directive to initialize your cache store:
+
+::
+
+  proxy_cache_path /var/cache/nginx/tileserver
+                   keys_zone=TileserverCache:50m
+                   levels=1:2
+                   inactive=2w
+                   max_size=10g;
+
+Make sure to give proper permissions for the /var/cache/nginx/tileserver folder. Usually nginx is running with www-data user.
+Enable caching on specific proxy pass:
+
+::
+
+  location / {
+    include proxy_params; 
+    proxy_pass http://127.0.0.1:8080/;
+
+    proxy_cache TileserverCache;
+    proxy_cache_valid 200 1w;
+
+    # add_header X-Cache-Status $upstream_cache_status;
+  }
+
+If you need to confirm whether caching works or not, uncomment the X-Cache-Status header. This will return a header on response with `HIT` or `MISS` header value which indicates if nginx cached the response or not.
+
+Make sure to clean your cache by removing files in the configured directory after you change your styles or tile information. You may experiment with the caching values to fit your needs.
+
+More about Nginx caching: https://docs.nginx.com/nginx/admin-guide/content-cache/content-caching/
+
+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 ensure the URLs generated inside TileJSON, etc. are using the desired domain and protocol.
+
+Nginx Reverse Proxy
+-----------
+
+An example nginx reverse proxy server configuration for HTTPS connections. It enables caching, CORS and Cloudflare Authenticated Pulls.
+
+::
+
+  proxy_cache_path /var/cache/nginx/tileserver
+                   keys_zone=TileserverCache:50m 
+                   levels=1:2
+                   inactive=2w
+                   max_size=1g;

+  * 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`` - ``((fill|stroke|width)\:[^\|]+\|)*((enc:.+)|((-?\d+\.?\d*,-?\d+\.?\d*\|)+(-?\d+\.?\d*,-?\d+\.?\d*)))``
+
+    * comma-separated ``lng,lat``, pipe-separated pairs
+
+      * e.g. ``path=5.9,45.8|5.9,47.8|10.5,47.8|10.5,45.8|5.9,45.8``
+
+    * `Google Encoded Polyline Format <https://developers.google.com/maps/documentation/utilities/polylinealgorithm>`_
+
+      * e.g. ``path=enc:_p~iF~ps|U_ulLnnqC_mqNvxq`@``
+      * If 'enc:' is used, the rest of the path parameter is considered to be part of the encoded polyline string -- do not specify the coordinate pairs.
+
+    * With options (fill|stroke|width)
+
+      * e.g. ``path=stroke:yellow|width:2|fill:green|5.9,45.8|5.9,47.8|10.5,47.8|10.5,45.8|5.9,45.8`` or ``path=stroke:blue|width:1|fill:yellow|enc:_p~iF~ps|U_ulLnnqC_mqNvxq`@``
+
+    * can be provided multiple times  
+
+  * ``latlng`` - indicates 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
+  * ``linecap`` - rendering style for the start and end points of the path
+  * ``linejoin`` - rendering style for overlapping segments of the path with differing directions
+  * ``border`` - color of the optional border path stroke
+  * ``borderwidth`` - width of the border stroke (default 10% of width)
+  * ``marker`` - Marker in format ``lng,lat|iconPath|option|option|...``
+
+    * Will be rendered with the bottom center at the provided location
+    * ``lng,lat`` and ``iconPath`` are mandatory and icons won't be rendered without them
+    * ``iconPath`` is either a link to an image served via http(s) or a path to a file relative to the configured icon path
+    * ``option`` must adhere to the format ``optionName:optionValue`` and supports the following names
+
+      * ``scale`` - Factor to scale image by
+
+        * e.g. ``0.5`` - Scales the image to half it's original size
+
+      * ``offset`` - Image offset as positive or negative pixel value in format ``[offsetX],[offsetY]``
+
+        * scales with ``scale`` parameter since image placement is relative to it's size
+        * e.g. ``2,-4`` - Image will be moved 2 pixel to the right and 4 pixel in the upwards direction from the provided location
+
+    * e.g. ``5.9,45.8|marker-start.svg|scale:0.5|offset:2,-4``
+    * can be provided multiple times
+
+  * ``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"
+
+  * ``maxzoom`` - Maximum zoom level (only for auto endpoint where zoom level is calculated and not provided)
+
+* 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``
+
+Health check
+============
+Endpoint reporting health status is at ``/health`` and currently returns:
+
+  * ``503`` Starting - for a short period before everything is initialized
+  * ``200`` OK - when the server is running

+============
+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 8080:8080 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 11:
+  * ``libgles2-mesa``
+  * ``libegl1``
+  * ``xvfb``
+  * ``xauth``
+  * ``libopengl0``
+  * ``libcurl4``
+  * ``curl``
+  * ``libuv1-dev``
+  * ``libc6-dev``
+  * ``http://archive.ubuntu.com/ubuntu/pool/main/libj/libjpeg-turbo/libjpeg-turbo8_2.0.3-0ubuntu1_amd64.deb``
+  * ``http://archive.ubuntu.com/ubuntu/pool/main/i/icu/libicu66_66.1-2ubuntu2_amd64.deb``
+
+These are required on Ubuntu 20.04:
+  * ``libcairo2-dev``
+  * ``libjpeg8-dev``
+  * ``libpango1.0-dev``
+  * ``libgif-dev``
+  * ``build-essential``
+  * ``g++``
+  * ``xvfb``
+  * ``libgles2-mesa-dev``
+  * ``libgbm-dev``
+  * ``libxxf86vm-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 v18 (nvm install 18) 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

+=====
+Usage
+=====
+
+Getting started
+======
+::
+
+  Usage: main.js tileserver-gl [mbtiles] [options]
+
+  Options:
+
+    -h, --help            output usage information
+    --mbtiles <file>      MBTiles file (uses demo configuration);
+                          ignored if the configuration file is also specified
+    -c, --config <file>   Configuration file [config.json]
+    -b, --bind <address>  Bind address
+    -p, --port <port>     Port [8080]
+    -C|--no-cors          Disable Cross-origin resource sharing headers
+    -u|--public_url <url> Enable exposing the server on subpaths, not necessarily the root of the domain
+    -V, --verbose         More verbose output
+    -s, --silent          Less verbose output
+    -v, --version         Version info
+
+
+Default preview style and configuration
+======
+
+- If no configuration file is specified, a default preview style (compatible with openmaptiles) is used.
+- If no mbtiles file is specified (and is not found in the current working directory), a sample file is downloaded (showing the Zurich area)
+
+Reloading the configuration
+======
+
+It is possible to reload the configuration file without restarting the whole process by sending a SIGHUP signal to the node process.
+
+- The `docker kill -s HUP tileserver-gl` command can be used when running the tileserver-gl docker container.
+- The `docker-compose kill -s HUP tileserver-gl-service-name` can be used when tileserver-gl is run as a docker-compose service.
+
+Docker and `--port`
+======
+
+When running tileserver-gl in a Docker container, using the `--port` option would make the container incorrectly seem unhealthy.
+Instead, it is advised to use Docker's port mapping and map the default port 8080 to the desired external port.
