Creates GitHub-native docs. README badges, CONTRIBUTING, issue/PR templates, repo metadata.
GitHub-native documentation patterns for .NET projects: README structure with NuGet/CI/coverage badges and installation instructions, CONTRIBUTING.md with fork-PR workflow and development setup, issue templates (bug report with .NET version and repro steps, feature request with problem/solution/alternatives), PR templates with testing checklist and breaking changes section, GitHub Pages setup for documentation sites, repository metadata (CODEOWNERS, FUNDING.yml, social preview, topics/tags), and Mermaid diagram embedding in README files.
Version assumptions: .NET 8.0+ baseline for code examples. GitHub Actions for CI badges. NuGet.org for package badges.
Cross-references: [skill:dotnet-gha-deploy] for GitHub Pages deployment pipelines, [skill:dotnet-release-management] for changelog format and versioning, [skill:dotnet-mermaid-diagrams] for .NET-specific Mermaid diagrams in READMEs, [skill:dotnet-project-structure] for project metadata context, [skill:dotnet-documentation-strategy] for doc platform selection.
A well-structured README provides immediate context for contributors and consumers of a .NET project.
Place badges at the top of the README, grouped by category:
# My.Library

**Badge categories for .NET projects:**
| Badge | Source | Notes |
| --------------- | ---------------------- | -------------------------------------------- |
| NuGet version | shields.io + nuget.org | Use package ID, not assembly name |
| NuGet downloads | shields.io + nuget.org | Shows adoption; use `dt` for total downloads |
| Build status | GitHub Actions | Link to the CI workflow |
| Code coverage | Codecov / Coveralls | Requires CI integration |
| License | shields.io | Match the license in the repo |
| .NET version | shields.io | Optional; shows minimum supported TFM |
### Recommended README Sections

### Architecture Diagram in README
Embed a Mermaid architecture diagram directly in the README for visual context. GitHub renders Mermaid fenced code
blocks natively:
````markdown
## Architecture
````mermaid
graph TB
subgraph Client
App["Consumer App"]
end
subgraph Library["My.Library"]
API["Public API Surface"]
Core["Core Engine"]
Cache["In-Memory Cache"]
end
App --> API
API --> Core
Core --> Cache
```text

See [skill:dotnet-mermaid-diagrams] for .NET-specific diagram patterns including C4-style architecture, sequence
diagrams for API flows, and class diagrams for domain models.

## CONTRIBUTING.md Patterns
### Fork-PR Workflow
````markdown
# Contributing to My.Library
Thank you for your interest in contributing! This document provides guidelines and instructions for contributing.
## Getting Started
1. Fork the repository
2. Clone your fork: `git clone https://github.com/YOUR-USERNAME/my-library.git`
3. Create a feature branch: `git checkout -b feature/my-feature`
4. Make your changes
5. Submit a pull request
## Development Setup
### Prerequisites
- [.NET 8.0 SDK](https://dotnet.microsoft.com/download/dotnet/8.0) or later
- An IDE: [Visual Studio 2022](https://visualstudio.microsoft.com/), [VS Code](https://code.visualstudio.com/) with C#
Dev Kit, or [JetBrains Rider](https://www.jetbrains.com/rider/)
### Building
````shell
dotnet restore
dotnet build
```bash
````
````
### Running Tests
````shell
dotnet test
```bash
To run tests with coverage:
```shell
dotnet test --collect:"XPlat Code Coverage"
```bash
### Coding Standards
- Follow the
[.NET coding conventions](https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/coding-style/coding-conventions)
- Use `dotnet format` to enforce code style before committing
- All public APIs must have XML documentation comments
- New features must include unit tests
## Pull Request Process
1. Update documentation for any changed public APIs
2. Add or update tests to cover your changes
3. Ensure all tests pass: `dotnet test`
4. Ensure code compiles without warnings: `dotnet build -warnaserror`
5. Update the CHANGELOG.md with your changes under the `[Unreleased]` section
6. The PR will be reviewed by a maintainer
## Reporting Issues
- Use the [Bug Report](.github/ISSUE_TEMPLATE/bug_report.md) template for bugs
- Use the [Feature Request](.github/ISSUE_TEMPLATE/feature_request.md) template for enhancements
