It's great having you contribute to this project

Welcome to the community :nerd_face:

If you would like to continue contributing to open source and would like to do it with an awesome inclusive community, you should join our Discord chat and our GitHub Organisation - we help and encourage each other to contribute to open source little and often 🤓 . Any questions let us know.

We tend not to use the wiki section in eddiehub repos. If this is specific to linkfree then it should have its own md file, if it’s more generic then maybe it should be part of the support repo and something we can link to from all other repos.
