 # tileserver-gl
+
+## Installation
+ - Make sure you have Node v4 or higher (`nvm install 4`)
+ - `npm install`
+
+## Configuration
+
+Create `config.json` file in the root directory.
+The config file can contain definition of several paths where the tiles will be served.
+
+Every path needs to have `root` specified. All other paths (in the config (`style`) **and** in the style (`sprites`, `glyphs`, `sources`, ...)) are relative to this root.
+
+For raster endpoints specify `style`, for serving raw `pbf` vector tiles specify `mbtiles` property.
+
+Alternative `domains` can be specified (array or comma-separated string). These will be used to generate tile urls for `index.json`.
+
+Every path can also have `options` object and its content is directly copied into served `index.json`.
+The `options.format` can be used to modify the extension in tile urls inside `index.json`, but the server will still serve all the supported formats.
+
+### Example configuration file
+
+Example styles can be downloaded from https://github.com/klokantech/osm2vectortiles-gl-styles.
+Rendered vector tiles can be found at http://osm2vectortiles.org/downloads/.
+
+```json
+{
+  "/basic": {
+    "root": "test_data",
+    "style": "styles/basic-v8.json",
+    "domains": [
+      "localhost:8080",
+      "127.0.0.1:8080"
+    ],
+    "options": {
+      "type": "overlay",
+      "bounds": [5.8559113, 45.717995, 10.5922941, 47.9084648]
+    }
+  },
+  "/hybrid": {
+    "root": "test_data",
+    "style": "styles/satellite-hybrid-v8.json",
+    "options": {
+      "format": "webp"
+    }
+  },
+  "/switzerland-vector": {
+    "root": "test_data",
+    "mbtiles": "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 `root`. (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.
+- The tiles itself are served at `/{basename}/{z}/{x}/{y}[@2x].{format}`
+  - The optional `@2x` (or `@3x`) part can be used to render HiDPI (retina) tiles
+- Static images (only for raster tiles) are rendered at:
+  - `/{basename}/static/{lon},{lat},{zoom}/{width}x{height}[@2x].{format}` (center-based)
+  - `/{basename}/static/{minx},{miny},{maxx},{maxy}/{zoom}[@2x].{format}` (area-based)
+- TileJSON at `/{basename}/index.json`
+- Array of all TileJSONs at `/index.json`
+- Available formats:
+  - raster: `png`, `jpg` (`jpeg`), `webp`
+  - vector: `pbf`
