+# Contributing to ComplexRegions.jl
+
+Thanks for your interest in contributing! Bug reports, feature requests,
+documentation improvements, and pull requests are all welcome.
+
+## Reporting issues
+
+Please open an issue on the [issue tracker](https://github.com/complexvariables/ComplexRegions.jl/issues).
+A good report includes:
+
+- the version of ComplexRegions.jl and Julia you are using (`] status` and `versioninfo()`),
+- a short, self-contained example that reproduces the problem, and
+- what you expected to happen versus what actually happened.
+
+## Development setup
+
+1. Fork and clone the repository.
+2. From the repository root, activate the project and instantiate its dependencies:
+
+   ```julia
+   julia --project=. -e 'using Pkg; Pkg.instantiate()'
+   ```
+
+3. Make your changes on a feature branch (not `master`).
+
+## Running the tests
+
+The test suite runs against both `Float64` and `BigFloat`, and includes
+[Aqua](https://github.com/JuliaTesting/Aqua.jl) quality checks and
+[JET](https://github.com/aviatesk/JET.jl) static analysis.
+
+```bash
+julia --project=. -e 'using Pkg; Pkg.test()'
+```
+
+or from the Julia REPL package mode:
+
+```julia
+] test
+```
+
+Please make sure the full suite passes before opening a pull request, and add
+tests covering any new behavior or bug fix.
+
+## Coding conventions
+
+- Follow the style of the surrounding code.
+- Types are capitalized (e.g. `Segment`, `Circle`); methods that merely produce
+  values of existing types are lowercase (e.g. `n_gon`).
+- Use `tolerance(T)` for floating-point comparisons rather than hardcoded values,
+  so that code works correctly across real types including `BigFloat`.
+- See [`CLAUDE.md`](CLAUDE.md) for a tour of the type hierarchy, design
+  conventions, and notes on extending the package with new curve or region types.
+
+## Pull requests
+
+- Keep each pull request focused on a single change.
+- Include a clear description of what the change does and why.
+- Update documentation and docstrings when behavior changes.
+- The CI workflow runs the test suite and reports coverage; please check that it
+  passes.
+
+## AI-assisted contributions
+
+Contributions developed with the help of large language models are welcome, but
+you must understand and review the code you submit; please do not open pull
+requests containing unreviewed generated code. If a contribution includes
+substantial AI-generated content, note that in the pull request. This mirrors
+the [Julia General registry guidance](https://github.com/JuliaRegistries/General).
+
+## License
+
+By contributing, you agree that your contributions will be licensed under the
+[MIT License](LICENSE) that covers this project.

 This package provides types and methods that are useful for working with curves and regions in the complex plane.
 
 Most functionality is provided through Julia types. Per Julia conventions, these are all capitalized. You use these capitalized names to create values of the type; e.g., [Segment](@ref) and [Circle](@ref).
 
-Other methods may create values of these types, but since they are not distinct types themselves, they are not capitalized. For example, the [`rectangle`](@ref) method creates a [Polygon](@ref).
+Other methods may create values of these types, but since they are not distinct types themselves, they are not capitalized. For example, the [`n_gon`](@ref) method creates a [Polygon](@ref).
 
 The methods in this package should work not only with the built-in `Complex` type, but also with the `Polar` and `Spherical` types from the [ComplexValues](https://complexvariables.github.io/ComplexValues.jl/stable/) package, which it re-exports.
 
 Please see the [documentation](https://complexvariables.github.io/ComplexRegions.jl/stable/) for more details.
 
+Please open an [issue][issues-url] if you encounter any problems.
+
 ## Installation
 
 The package can be installed with Julia's package manager:
 
-```julia
+```julia-repl
 julia> import Pkg
 julia> Pkg.add("ComplexRegions")
 ```
-or just use ```] add ComplexRegions``` at the usual command prompt.
 
-## Project Status
+Or, just type ```] add ComplexRegions``` at the usual command prompt.
+
+## AI disclosure
+
+Claude has been used since version 0.3.6 to assist with finding bugs, identifying and fixing performance issues such as type stability, updating package maintenance tools, and consultations on making refactors and improvements. All AI work has been incremental and human-supervised. The original handwritten tests have never been removed.
