+# Contributing to WeatherMaster
+
+Thanks for contributing to WeatherMaster :P Before opening a PR, please read
+through the guidelines below. They are intended to keep the codebase
+consistent and make contributions easier to review and maintain
+
+## Before Contributing
+
+Before starting work on a contribution, please open an issue first and
+describe what you would like to change.
+
+For small changes like typo fixe or other
+obvious minor fixes, opening an issue is optional
+
+## General stuff
+
+- Keep changes focused and avoid unrelated refactors.
+- Follow the existing architecture and patterns used in the project.
+- Prefer reusing existing abstractions over introducing new ones.
+- Don't introduce a new pattern or framework for a single feature.
+- Keep platform-independent logic independent of UI code where
+  possible
+- Avoid unnecessary changes to existing behavior.
+
+## Adding a New Weather Source
+
+The goal is that adding a new source should primarily require changes to the
+source itself, rather than adding special cases throughout the codebase
+
+When implementing a new source:
+
+- Use the existing source abstractions and interfaces.
+- Do not add source-specific UI.
+- Do not add source-specific logic to existing UI components.
+- If the source requires information that the existing architecture cannot
+  represent, discuss the change before implementing a
+  source-specific workaround
+
+## AI-Assisted Contributions
+
+AI tools are allowed, but contributors are expected to understand and take
+ownership of the code they submit
+
+Please disclose AI usage in your PR description, including what the AI was
+used for
+
+PRs that appear to be largely or entirely AI-generated without meaningful
+review, understanding, or contribution from the author will be closed
+
+_Thanks :P_
