-I2PTunnel for Go
+# Go I2PTunnel
-================
 
-Implementation of I2PTunnel for go which includes equivalents of all I2PTunnel functionality.
+A Go implementation of I2P tunneling services with support for TCP, HTTP, UDP, and IRC protocols. Built on SAMv3, this project provides encrypted anonymous network tunnels with filtering, rate-limiting, and encrypted leaseSet capabilities.
-Implements middleware in libraries to handle filtering, rate-limiting, and encrypted leaseSets.
-Everything is backed by SAMv3.

+
+## Configuration
+
+Each tunnel type supports these common options:

+- `type` - Tunnel type (server/client)
+- `port` - Local port to bind
+- `host` - Local host to bind (default: 127.0.0.1)
+- `keys` - Path to key file
+- `destination` - Target I2P address (clients only)

-I2PTunnel Interface
+# I2PTunnel Core Interface
-===================
 
+A Go package that defines the standard interface for I2P tunnel implementations. This core library provides the contract that all I2P tunnel types must implement to be compatible with I2PTunnel controllers.
+
+## Features
+
+- Standardized interface for I2P tunnel implementations
+- Type-safe tunnel state management via constants
+- Universal control methods for all tunnel types
+- Common configuration and error handling patterns
+
+## Installation
+
+```bash
+go get github.com/go-i2p/go-i2ptunnel/lib/core
+```
+
+## Usage Example
+
+```go
+// filepath: example/mytunnel.go
+package mytunnel
+
+import "github.com/go-i2p/go-i2ptunnel/lib/core"
+
+type MyTunnel struct {
+    name    string
+    status  i2ptunnel.I2PTunnelStatus
+    options map[string]string
+}
+
+// Implement the I2PTunnel interface
+func (t *MyTunnel) Start() error {
+    t.status = i2ptunnel.I2PTunnelStatusStarting
+    // Your tunnel startup logic here
+    return nil
+}
+
+func (t *MyTunnel) Status() i2ptunnel.I2PTunnelStatus {
+    return t.status
+}
+
+// Implement remaining required methods...
+```
+
+## Required Interface Methods
+
+All tunnel implementations must provide:
+
+- `Start()` - Initialize and start the tunnel
+- `Stop()` - Gracefully shutdown the tunnel
+- `Name()` - Get tunnel identifier
+- `Type()` - Get tunnel type
+- `Address()` - Get I2P destination address
+- `Target()` - Get target I2P address
+- `Options()` - Get configuration options
+- `Status()` - Get current state
+- `Error()` - Get error state
+- `LocalAddress()` - Get local endpoint
+
+## Tunnel States
+
+- `Running` - Active and operational
+- `Stopped` - Inactive
+- `Starting` - In startup process
+- `Stopping` - In shutdown process
+- `Failed` - Error state
+- `Unknown` - Indeterminate state
+
+## Testing
+
+```bash
+# Run unit tests
+go test ./...
+
+# Test your implementation
+go test -v -run TestYourTunnel
+```

 HTTP Tunnels
 ============
 
-HTTP Tunnels are especially for HTTP Services(httpserver) and HTTP User-Agents(httpclient).
+HTTP Tunnels are designed for HTTP Services (httpserver) and HTTP User-Agents (httpclient).
 
 HTTP Client
 -----------
 
+The HTTP Client implements a proxy server that enables HTTP/S traffic between local applications and I2P network services. It acts as an intermediary, handling all standard HTTP methods and CONNECT requests.
 
+```
+[Browser/App] <-> [I2P HTTP Client] <-> [I2P Network] <-> [I2P Services]
+    :8118           (HTTP Proxy)         Encrypted        Web Servers

+               - Header management  
+               - Connection routing
+```
+
+Key features:
+- Supports HTTP, HTTPS and CONNECT methods
+- Proxies requests between local clients and I2P services
+- Manages HTTP headers and connection states
+- Handles protocol negotiation and routing
 
 HTTP Server
 -----------
 
+The HTTP Server implements a reverse proxy that forwards traffic between local services and I2P clients. It acts as an intermediary, providing access control and traffic management.
 
+```
+[Local Service] <-> [I2P HTTP Server] <-> [I2P Network] <-> [I2P Clients]
+    :8080            (Reverse Proxy)        Encrypted        Browser/App

+                - Rate limiting
+                - Access control
+```
+
+Key features:
+- Forwards requests between local services and I2P network
+- Filters and modifies HTTP headers
+- Rate limits incoming requests
+- Provides access control for I2P clients

 UDP Tunnels
 ===========
 
-UDP Tunnels are not "Standard" in that they are not included in Java I2P.
+UDP tunnels provide transparent packet forwarding between I2P and local UDP endpoints. Key characteristics:
-These tunnels do no filtering, and pass traffic unmodified end-to-end.
+
+- Non-standard implementation (not included in Java I2P)
+- Direct packet forwarding without modification
+- No protocol filtering or inspection
+- End-to-end UDP datagram transport
+- Bidirectional tunnel support
+
+The tunnel suite includes both client and server components for creating complete UDP connectivity through I2P.
 
 UDP Server Tunnels
 ------------------
@@ -30,3 +37,17 @@ UDP Client Tunnels
 
 UDP Client Tunnels accept incoming UDP packets and forward them as I2P Datagrams to an I2P destination. This enables:
 
+- Accessing remote I2P UDP services locally
+- Connecting to game servers hosted on I2P
+- Forwarding local UDP traffic through I2P
+- Simple client-side UDP tunneling
+
+Key features:
+* Transparent UDP forwarding
+* Direct destination addressing
+* Local UDP socket binding
+* Stateless operation
+
+When sending UDP packets to an I2P service, the traffic flows:
+- Outgoing: Local Client → UDP Packet → I2P Client → I2P Network
+- Incoming: I2P Network → I2P Client → UDP Packet → Local Client
