Feature Request: "New Feature Walkthrough"

Documentation on how to use this repository and match the pattern while adding a new feature would be extremely helpful.
Something similar to [this.](https://github.com/NoQuarterTeam/boilerplate/blob/main/docs/new-feature.md)

Start by reviewing the linked docs/new-feature.md example and the repository's existing documentation structure. Document how to use this repository and follow its pattern when adding a feature; done means a newcomer can use the guide to understand the workflow and conventions.
