When a Slack chat message receives a specific emoji reaction, this package creates a GitHub issue with a link to that message.
This feature is for teams who use Slack to communicate and GitHub to track issues. It provides an easy way to file an issue (just add a specific emoji to a message), which helps team members (even non-technical ones!) quickly document or act upon important parts of conversations.
