Building on Arch Linux

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

Please see our Continuous Integration script for more details.

A Docker-based building & testing setup pipeline is also available here for your convenience.

sudo cp -av /tmp/mod_tile_src/utils/example-map /usr/share/renderd/example-map

# Add configuration
