I have been developing Bootscout for about 2 years at the time of writing as a pet project for my district. As of January 2019 I have started to advertise Bootscout (mainly letting people know about its existence via scout forums) and I am now looking for more developers to contribute.
To get involved all you need is know how to develop in PHP, JS, HTML and CSS along with have an account on GitHub. Next, fork the repository and start developing. This could be anything from new features to bug fixes. Once done submit a pull request and I will review the changes and merge back into Bootscout.
