+## Using with OpenLayers
+
+[OpenLayers](https://github.com/openlayers/openlayers) is an open source library for creating interactive maps on the web. Similar to [MapLibre GL JS](https://maplibre.org/), it can also display image and vector map tiles served by Martin Tile Server.
+
+You can integrate tile services from `martin` and `OpenLayers` with its [VectorTileLayer](https://openlayers.org/en/latest/apidoc/module-ol_layer_VectorTile-VectorTileLayer.html). Here is an example to add `MixPoints` vector tile source to an OpenLayers map.
+
+```js
+const layer = new VectorTileLayer({
+    source: new VectorTileSource({
+        format: new MVT(),
+        url: 'http://0.0.0.0:3000/MixPoints/{z}/{x}/{y}',
+        maxZoom: 14,
+    }),
+});
+map.addLayer(layer);
+```
