 ## Server
 If you want to run a server with the web api you also need to install other dependencies.
 To install openssl headers on a debian-based distribution execute: `apt install libssl-dev`.
 On an arch based distribution you can use `pacman -S openssl`.
 Then install the lua modules using luarocks: `luarocks --lua-version 5.1 install luasec`
 
 To run the web api server with tls you need to set the environment variables `TLS_KEY` and `TLS_CERT` to point to their respective .pem files.
