# Building on openSUSE

This document provides users with step-by-step instructions on how to compile and use`mod_tile` and `renderd`.

Please see our [Continuous Integration script](/.github/workflows/build-and-test.yml) for more details.

A Docker-based building & testing setup pipeline is also available [here](/docker) for your convenience.

_openSUSE does not provide a `mapnik`/`mapnik-devel` package, so it will first need to be built & installed, which is beyond the scope of this document, please visit the project's [installation document on GitHub](https://github.com/mapnik/mapnik/blob/master/INSTALL.md) or our [Continuous Integration script](/.github/actions/dependencies/build-and-install/mapnik/action.yml) for more information._
