It is kinda hard for non-experienced developer to deal with new software especially when there is minimum information about how does it work. I find config doc for Riot not very descriptive. For example, there are no explanation for enable_presence_by_hs_url and hosting_signup_link options at all while in sample JSON config (https://riot.im/develop/config.json) these elements are presented. My suggestion is to improve Riot configuration documentation.
