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.

README Structure for .NET Projects
A well-structured README provides immediate context for contributors and consumers of a .NET project.
Badges
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
My.Library
[badges here]
Short one-paragraph description of what the library does and why it exists.
Installation
dotnet add package My.Library
Or via PackageReference in your .csproj:
<PackageReference Include="My.Library" Version="1.0.0" />
Quick Start
using My.Library;
var service = new WidgetService();
var widget = await service.CreateWidgetAsync("example");
Console.WriteLine(widget.Id);

Architecture Diagram in README
Embed a Mermaid architecture diagram directly in the README for visual context. GitHub renders Mermaid fenced code blocks natively:
Architecture
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
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.

GitHub Pages Setup
GitHub Pages can host documentation sites generated by Starlight, Docusaurus, or DocFX. This section covers the repository configuration; CI deployment pipeline configuration belongs to [skill:dotnet-gha-deploy].
Repository Settings
- Navigate to Settings > Pages
- Under Source, select GitHub Actions (not the legacy branch-based deployment)
- The deployment workflow in .github/workflows/
handles the build and publish steps
Doc Site Directory Structure
Place documentation source files in a docs/
directory at the repository root:
my-library/
src/
MyLibrary/
MyLibrary.csproj
docs/
astro.config.mjs # For Starlight
# OR docusaurus.config.js # For Docusaurus
# OR docfx.json # For DocFX
.github/
workflows/
deploy-docs.yml # Deployment workflow -- see [skill:dotnet-gha-deploy]
README.md
CONTRIBUTING.md
Custom Domain
Configure a custom domain for GitHub Pages:
- Add a CNAME
file in the doc site's static directory (e.g., docs/public/CNAME
for Starlight, docs/static/CNAME
for Docusaurus)
- Set the domain in Settings > Pages > Custom domain
- Enable Enforce HTTPS
Content in the CNAME
file:
docs.mylibrary.dev
For documentation platform selection and configuration, see [skill:dotnet-documentation-strategy]. For deployment workflow YAML, see [skill:dotnet-gha-deploy].
Repository Metadata
CODEOWNERS
Define code ownership for automated review assignment:
# .github/CODEOWNERS
# Default owner for everything
* @mycompany/core-team
# Documentation
/docs/ @mycompany/docs-team
*.md @mycompany/docs-team
# Source code by area
/src/MyLibrary.Core/ @mycompany/core-team
/src/MyLibrary.Data/ @mycompany/data-team
# Build and CI
/.github/ @mycompany/devops-team
/build/ @mycompany/devops-team
*.props @mycompany/core-team
*.targets @mycompany/core-team
# NuGet configuration
nuget.config @mycompany/core-team
Directory.Packages.props @mycompany/core-team
FUNDING.yml
Configure GitHub Sponsors and other funding links:
# .github/FUNDING.yml
github: [maintainer-username]
open_collective: my-library
custom: ["https://www.buymeacoffee.com/maintainer"]
Social Preview
- Navigate to Settings > General > Social preview
- Upload a 1280x640 image (2:1 aspect ratio)
- Include: project name, logo, brief tagline, and .NET version badge
- Use a consistent brand color scheme
Topics and Tags
Add repository topics for discoverability:
- dotnet
, csharp
, nuget
-- ecosystem tags
- library
, sdk
, framework
-- project type
- aspnetcore
, efcore
, blazor
-- technology-specific tags
- Descriptive tags: serialization
, logging
, dependency-injection
, etc.
Set topics in Settings > General > Topics or via the repository description area on the main page.
Repository Description
Keep the repository description concise (under 350 characters). Include:
- What the project does
- Key differentiator or primary use case
- Target .NET version if relevant
Example: "High-performance JSON serialization library for .NET 8+ with source generator support and AOT compatibility."
Agent Gotchas
-
Always use YAML-based issue templates (.yml
), not Markdown templates (.md
) -- YAML templates provide structured form fields with validation, dropdowns, and required fields. Markdown templates are the legacy format and offer no input validation.
-
The .github/ISSUE_TEMPLATE/
directory must contain a config.yml
-- without it, the "blank issue" option appears by default. Set blank_issues_enabled: false
to force users through templates.
-
Badge URLs must use the correct NuGet package ID -- the package ID is case-sensitive on shields.io. Use the exact ID from NuGet.org (e.g., Newtonsoft.Json
, not newtonsoft.json
).
-
CODEOWNERS patterns follow .gitignore
syntax -- use /src/
for root-relative paths. Without the leading /
, the pattern matches anywhere in the tree.
-
GitHub Pages source must be set to "GitHub Actions" -- the legacy "Deploy from a branch" mode does not support custom build steps. The GitHub Actions source delegates build and deployment to a workflow. For the workflow YAML, see [skill:dotnet-gha-deploy].
-
Do not generate CI/CD deployment YAML in this skill -- deployment workflows for GitHub Pages belong to [skill:dotnet-gha-deploy]. This skill covers repository structure and template content only.
-
Do not generate changelog content -- changelog format, versioning strategy, and release notes belong to [skill:dotnet-release-management]. Reference CHANGELOG.md in the README but do not define its format here.
-
PR template file must be named exactly pull_request_template.md
-- GitHub only recognizes this exact filename (case-insensitive). It can live in the root, docs/
, or .github/
directory. The .github/
location is recommended for consistency with issue templates.
-
Include .NET Version
in bug report templates -- .NET version is critical for reproducing bugs. Use dotnet --version
output as the expected format. Include OS as a dropdown since behavior often varies across platforms.
-
Mermaid diagrams in README render natively on GitHub -- no special configuration is needed. Use standard fenced code blocks with the mermaid
language identifier. See [skill:dotnet-mermaid-diagrams] for .NET-specific diagram patterns to embed in architecture sections.
