+A high-performance Go implementation of the [Reticulum Network Stack](https://github.com/markqvist/Reticulum)
+
+## Project Goals:
+
+- **Full Protocol Compatibility**: Maintain complete interoperability with the Python reference implementation
+- **Cross-Platform Support**: Support for legacy and modern platforms across multiple architectures
+- **Performance**: Leverage Go's concurrency model and runtime for improved throughput and latency
+- **More Privacy and Security**: Additional privacy and security features beyond the base specification
+
+## Prerequisites
+
+- Go 1.24 or later
+- [Task](https://taskfile.dev/) for build automation
+
+Note: You may need to set `alias task='go-task'` in your shell configuration to use `task` instead of `go-task`.
+
+### Nix
+
+If you have Nix installed, you can use the development shell which automatically provides all dependencies including Task:
+
+```bash
+nix develop
+```
+
+This will enter a development environment with Go and Task pre-configured.
+
+## Quick Start
+
+### Building the Binary
+
+```bash
+task build
+```
+
+The compiled binary will be located in `bin/reticulum-go`.
+
+### Running the Application
+
+```bash
+task run
+```
+
+### Running Tests
+
+```bash
+task test
+```
+
+## Development
+
+### Code Quality
+
+Format code:
+
+```bash
+task fmt
+```
+
+Run static analysis checks (formatting, vet, linting):
+
+```bash
+task check
+```
+
+### Testing
+
+Run all tests:
+
+```bash
+task test
+```
+
+Run short tests only:
+
+```bash
+task test-short
+```
+
+Generate coverage report:
+
+```bash
+task coverage
+```
+
+### Benchmarking
+
+Run benchmarks with standard GC:
+
+```bash
+task bench
+```
+
+Run benchmarks with experimental Green Tea GC:
+
+```bash
+task bench-experimental
+```
+
+Compare both GC implementations:
+
+```bash
+task bench-compare
+```
+
+## Tasks
+
+The project uses [Task](https://taskfile.dev/) for all development and build operations.
+
+```
