+## Goals
 
-[Reticulum Network](https://github.com/markqvist/Reticulum) implementation in Go `1.24+`.
+- To be fully compatible with the Python reference implementation.
+- Additional privacy and security features.
+- Support for a broader range of platforms and architectures old and new.
 
-Aiming to be fully compatible with the Python version. 
+## Quick Start
 
-## Usage
+### Prerequisites
 
-Requires Go 1.24+
+- Go 1.24 or later
 
-```
-make install
+### Build
+
+```bash
 make build
+```
+
+### Run
+
+```bash
 make run
 ```
 
-## Linter
-
-[Revive](https://github.com/mgechev/revive)
+### Test
 
 ```bash
-revive -config revive.toml -formatter friendly ./pkg/* ./cmd/* ./internal/*
+make test
 ```
 
-## External Packages
+## Embedded systems and WebAssembly
 
-- `golang.org/x/crypto` `v0.39.0` - Cryptographic primitives
+For building for WebAssembly and embedded systems, see the [tinygo branch](https://github.com/Sudo-Ivan/Reticulum-Go/tree/tinygo). Requires TinyGo 0.37.0+.
+
+```bash
+make tinygo-build
+make tinygo-wasm
+```
+
+### Experimental Features
+
+Build with experimental Green Tea GC (Go 1.25+):
+
+```bash
+make build-experimental
+```

+# Reticulum-Go MicroVM
+
+Minimal Firecracker microVM setup for running Reticulum-Go.
+
+## Prerequisites
+
+- Firecracker binary installed
+- Go compiler
+- Root privileges (for network setup and KVM access)
+- Linux host system with KVM support
+- Access to `/dev/kvm`
+
+## Important: Nested Virtualization
+
+**If running inside a QEMU/KVM VM**, nested virtualization must be enabled:
+
+1. **Host QEMU configuration**: Start your QEMU VM with nested KVM:
+   ```bash
+   qemu-system-x86_64 -cpu host -enable-kvm -machine q35,accel=kvm ...
+   ```
+
+2. **Enable nested KVM on host** (if not already):
+   ```bash
+   # Check if nested is enabled
+   cat /sys/module/kvm_intel/parameters/nested  # Intel
+   cat /sys/module/kvm_amd/parameters/nested    # AMD
+   
+   # Enable nested (Intel)
+   echo "options kvm_intel nested=1" | sudo tee /etc/modprobe.d/kvm.conf
+   
+   # Enable nested (AMD)
+   echo "options kvm_amd nested=1" | sudo tee /etc/modprobe.d/kvm.conf
+   
+   # Reboot host
+   ```
+
+3. **Inside the VM**, check if `/dev/kvm` exists:
+   ```bash
+   ls -l /dev/kvm
+   ```
+
+**Alternative**: If nested virtualization isn't available, consider:
+- Running Firecracker directly on the host machine
+- Using QEMU directly instead of Firecracker
+- Using Docker/LXC containers instead
+
+## KVM Setup
+
+Ensure your user has access to `/dev/kvm`:
+
+```bash
+# Check if /dev/kvm exists
+ls -l /dev/kvm
+
+# Add your user to the kvm group (recommended)
+sudo usermod -aG kvm $USER
+
+# Or set ACL (alternative)
+sudo setfacl -m u:$USER:rw /dev/kvm
+
+# Log out and back in for group changes to take effect
+```
+
+## Setup
+
+Run the setup script:
+
+```bash
+./setup.sh
+```
+
+This will:
+- Check for Firecracker installation
+- Download vmlinux.bin kernel
+- Build Reticulum-Go binary
+- Create rootfs.ext4 disk image
+- Generate firecracker-config.json
+
+## Running
+
+1. Create tap interface:
+```bash
+sudo ip tuntap add tap0 mode tap
+sudo ip addr add 172.16.0.1/24 dev tap0
+sudo ip link set tap0 up
+```
+
+2. Enable IP forwarding:
+```bash
+sudo sysctl -w net.ipv4.ip_forward=1
+```
+
+3. Start Firecracker:
+```bash
+# Clean up any old socket files first
+rm -f /tmp/firecracker.sock microvm/vsock.sock
+
+firecracker --api-sock /tmp/firecracker.sock --config-file firecracker-config.json
+```
+
+4. Connect to console (in another terminal):
+```bash
+firecracker --api-sock /tmp/firecracker.sock
+```
+
+## Configuration
+
+- **CPU**: 1 vCPU
+- **Memory**: 128 MiB
+- **Network**: tap0 interface
+- **Disk**: rootfs.ext4 (100MB)
+
+Modify `firecracker-config.json` to adjust resources.
+
+## Files
+
+- `vmlinux.bin` - Linux kernel
+- `rootfs.ext4` - Root filesystem with binary
+- `firecracker-config.json` - Firecracker configuration
+- `reticulum-go` - Compiled binary
+
