+# DotNet Dispatcher Repository Overview
+
+## Purpose
+**DotNet Dispatcher** is a lightweight, compile-time generated CQRS dispatcher for .NET that eliminates runtime reflection, making it highly AOT-friendly and performance-efficient. It leverages Roslyn code generation to automatically generate dispatchers at compile time, providing a zero-reflection, high-performance alternative to traditional CQRS implementations like MediatR.
+
+## General Setup
+The repository is organized with the following key components:
+
+- **src/DotnetDispatcher**: Contains the core dispatcher interfaces and base classes
+- **src/DotnetDispatcher.Generator**: Contains the Roslyn source generator that creates the dispatcher implementations
+- **test**: Contains unit tests for the dispatcher functionality
+- **build**: Contains build scripts and configuration using Nuke build system
+- **.github/workflows**: Contains GitHub Actions workflows for CI/CD
+
+## Repository Structure

+
+## CI/CD Pipelines
+The repository includes three main GitHub Actions workflows:
+
+1. **Continuous_build.yml**: Runs on every push, performing:
+   - Clean build
+   - Compilation
+   - Unit testing
+   - Packaging
+
+2. **Build_main_and_publish_to_nuget.yml**: Triggers on version tags (v*), performing:
+   - Clean build
+   - Compilation
+   - Packaging
+   - Publishing to GitHub NuGet
+   - Artifact publishing
+
+3. **Manual_publish_to_Github_Nuget.yml**: Manual trigger for:
+   - Packaging
+   - Publishing to GitHub NuGet
+   - Artifact publishing
+
+## Code Quality
+- Uses Nuke build system for consistent build processes
+- Includes .editorconfig for C# code style enforcement
+- Follows Roslyn analyzer rules for code quality
+- Comprehensive unit test coverage
+
