[dev] Need a little help for dev start

Hello, before I get lost in the source, it would help if I could get some basic infos. Can somebody give me a very short intro to the architecture of otrs 3? I want to add a new ticket function - something like "Send summary of ticket". Can/Should this be implemented as a package? Is there somewhere a discription how to create a package?
