summary
Step‑by‑step walkthrough that starts from bundle gem and ends with gem push, showing a working gem scaffolded, configured, and published. Covers concrete patterns for managing gem configuration, how to integrate with Rails’ boot and configuration, tradeoffs of being a Rails Engine versus a plain gem, and test setup that runs against multiple Rails versions (CI matrix). Demonstrates the actual build, test, and publish flow so the gem really works.
