 OpenMapTiles is an extensible and open tile schema based on the OpenStreetMap. It is used to generate vector tiles for online zoomable maps. The project is about creating a beautiful basemaps with general layers that contain topographic information. More information [openmaptiles.org](http://openmaptiles.org/) and [openmaptiles.com](http://openmaptiles.com/).
 
-We encourage you to collaborate, reuse and adapt existing layers and add your own layers or use our approach for your own vector tile project. Feel free to fork the repo and experiment. The repository is built on top of the [openmaptiles/tools](https://github.com/openmaptiles/openmaptiles-tools) to simplify vector tile creation.
