+# Redis Server Package
+
+A lightweight, in-memory Redis-compatible server implementation in Go. This package provides a Redis-like server that can be embedded in your Go applications.
+
+## Features
+
+- Supports both TCP and Unix socket connections
+- In-memory data storage with key expiration
+- Implements common Redis commands
+- Thread-safe operations
+- Automatic cleanup of expired keys
+
+## Supported Commands
+
+The server implements the following Redis commands:
+
+- Basic: `PING`, `SET`, `GET`, `DEL`, `KEYS`, `EXISTS`, `TYPE`, `TTL`, `INFO`, `INCR`
+- Hash operations: `HSET`, `HGET`, `HDEL`, `HKEYS`, `HLEN`
+- List operations: `LPUSH`, `RPUSH`, `LPOP`, `RPOP`, `LLEN`, `LRANGE`
+- Cursor-based iteration: `SCAN`, `HSCAN`
+
+## Usage
+
+### Basic Usage
+
+```go
+import "github.com/freeflowuniverse/heroagent/pkg/redisserver"
+
+// Create a new server with default configuration
+server := redisserver.NewServer(redisserver.ServerConfig{
+    TCPPort: "6379",                  // TCP port to listen on
+    UnixSocketPath: "/tmp/redis.sock" // Unix socket path (optional)
+})
+
+// The server starts automatically and runs in background goroutines
+```
+
+### Connecting to the Server
+
+You can connect to the server using any Redis client. For example, using the `go-redis` package:
+
+```go
+import "github.com/redis/go-redis/v9"
+
+// Connect via TCP
+client := redis.NewClient(&redis.Options{
+    Addr: "localhost:6379",
+})
+
+// Or connect via Unix socket
+unixClient := redis.NewClient(&redis.Options{
+    Network: "unix",
+    Addr:    "/tmp/redis.sock",
+})
+```

+# Redis Server Test Tool
+
+This tool provides comprehensive testing for the Redis server implementation in the `pkg/redisserver` package.
+
+## Features
+
+- Tests both TCP and Unix socket connections
+- Organized test suites for different Redis functionality:
+  - Connection tests
+  - String operations
+  - Hash operations
+  - List operations
+  - Pattern matching
+  - Miscellaneous operations
+- Detailed test results with pass/fail status and error information
+- Summary statistics for overall test coverage
+
+## Usage
+
+```bash
+go run main.go [options]
+```
+
+### Options
+
+- `-tcp-port string`: Redis server TCP port (default "7777")
+- `-unix-socket string`: Redis server Unix domain socket path (default "/tmp/redis-test.sock")
+- `-debug`: Enable debug output (default false)
+- `-db int`: Redis database number (default 0)
+
+## Example
+
+```bash
+# Run with default settings
+go run main.go
+
+# Run with custom port and socket
+go run main.go -tcp-port 6379 -unix-socket /tmp/custom-redis.sock
+
+# Run with debug output
+go run main.go -debug
+```
+
+## Test Coverage
+
+The tool tests the following Redis functionality:
+
+1. **Connection Tests**
+   - PING
+   - INFO
+
+2. **String Operations**
+   - SET/GET
+   - SET with expiration
+   - TTL
+   - DEL
+   - EXISTS
+   - INCR
+   - TYPE
+
+3. **Hash Operations**
+   - HSET/HGET
+   - HKEYS
+   - HLEN
+   - HDEL
+   - Type checking
+
+4. **List Operations**
+   - LPUSH/RPUSH
+   - LLEN
+   - LRANGE
+   - LPOP/RPOP
+   - Type checking
+
+5. **Pattern Matching**
+   - KEYS with various patterns
+   - SCAN with patterns
+   - Wildcard pattern matching
+
+6. **Miscellaneous Operations**
+   - FLUSHDB
+   - Multiple sequential operations
+   - Non-existent key handling
