+```
+
+## Steps to Add a New Redis Command
+
+### 1. Implement the Command in `commands.py`
+
+Add your command method to the `Commands` class:
+
+```python
+# filepath: upstash_redis/commands.py
+def your_new_command(self, key: str, *args, **kwargs) -> CommandsProtocol:
+    """
+    Description of your command.
+    
+    Args:
+        key: The Redis key
+        *args: Additional arguments
+        **kwargs: Additional keyword arguments
+    
+    Returns:
+        CommandsProtocol: Command object for execution
+    """
+    return self._execute_command("YOUR_REDIS_COMMAND", key, *args, **kwargs)
+```
+
+### 2. Add Type Hints in `commands.pyi`
+
+Update the type stub file with your command signature:
+
+```python
+# filepath: upstash_redis/commands.pyi
+def your_new_command(self, key: str, *args, **kwargs) -> CommandsProtocol: ...
+```
+
+### 3. Update Client Classes (if needed)
+
+If your command requires special handling, update both sync and async clients:
+
+```python
+# filepath: upstash_redis/client.py
+# Add any client-specific logic if needed
+
+# filepath: upstash_redis/asyncio/client.py  
+# Add async version if special handling is needed
+```
+
+### 4. Add Response Formatting (if needed)
+
+If your command returns data that needs special formatting, add a formatter in `format.py`:
+
+```python
+# filepath: upstash_redis/format.py
+def format_your_command_response(response: Any) -> YourReturnType:
+    """Format the response from your Redis command."""
+    # Implementation here
+    pass
+```
+
+### 5. Write Comprehensive Tests
+
+Create test files in the appropriate category folder:
+
+```python
+# filepath: tests/commands/{category}/test_your_new_command.py
+import pytest
+from upstash_redis import Redis
+
+def test_your_new_command_basic():
+    """Test basic functionality of your new command."""
+    redis = Redis.from_env()
+    result = redis.your_new_command("test_key", "arg1", "arg2")
+    # Add assertions
+
+def test_your_new_command_edge_cases():
+    """Test edge cases and error conditions."""
+    # Add edge case tests
+
+# If async support is needed:
+# filepath: tests/commands/asyncio/test_your_new_command.py
+import pytest
+from upstash_redis.asyncio import Redis as AsyncRedis
+
+@pytest.mark.asyncio
+async def test_your_new_command_async():
+    """Test async version of your new command."""
+    redis = AsyncRedis.from_env()
+    result = await redis.your_new_command("test_key", "arg1", "arg2")
+    # Add assertions
+```
+
+### 6. Update Package Exports (if needed)
+
+If you're adding a new public class or function, update `__init__.py`:
+
+```python
+# filepath: upstash_redis/__init__.py
+from upstash_redis.your_new_module import YourNewClass
+
+__all__ = ["AsyncRedis", "Redis", "YourNewClass"]
+```
+
+## Command Categories and Organization
+
+Commands are typically organized into these categories:
+
+- **String**: Basic key-value operations (`GET`, `SET`, etc.)
+- **Hash**: Hash field operations (`HGET`, `HSET`, etc.)
+- **List**: List operations (`LPUSH`, `RPOP`, etc.)
+- **Set**: Set operations (`SADD`, `SREM`, etc.)
+- **Sorted Set**: Sorted set operations (`ZADD`, `ZREM`, etc.)
+- **JSON**: JSON operations (`JSON.GET`, `JSON.SET`, etc.)
+- **Generic**: Key management (`DEL`, `EXISTS`, etc.)
+- **Server**: Server management commands
+
+## Testing Guidelines
+
+1. **Test file naming**: `test_{command_name}.py`
+2. **Test function naming**: `test_{command_name}_{scenario}`
+3. **Include both positive and negative test cases**
+4. **Test with different data types and edge cases**
+5. **Add async tests if the command supports async operations**
+6. **Use appropriate fixtures from `conftest.py`**
+
+## Example: Adding a New Hash Command
+
+Here's a complete example of adding a hypothetical `HMERGE` command:
+
+```python
+# filepath: upstash_redis/commands.py
+def hmerge(self, key: str, source_key: str) -> CommandsProtocol:
+    """
+    Merge hash from source_key into key.
+    
+    Args:
+        key: Destination hash key
+        source_key: Source hash key to merge from
+    
+    Returns:
+        CommandsProtocol: Command for execution
+    """
+    return self._execute_command("HMERGE", key, source_key)
+```
+
+```python
+# filepath: tests/commands/hash/test_hmerge.py
+import pytest
+from upstash_redis import Redis
+
+def test_hmerge_basic(redis_client):
+    """Test basic HMERGE functionality."""
+    redis = redis_client
+    
+    # Setup
+    redis.hset("hash1", {"field1": "value1", "field2": "value2"})
+    redis.hset("hash2", {"field3": "value3", "field2": "overwrite"})
+    
+    # Execute
+    result = redis.hmerge("hash1", "hash2")
+    
+    # Verify
+    merged_hash = redis.hgetall("hash1")
+    assert merged_hash["field1"] == "value1"
+    assert merged_hash["field2"] == "overwrite"  # Should be overwritten
+    assert merged_hash["field3"] == "value3"     # Should be added
+```
+
+## Running Tests
+
+To run tests for your new command:
+
+```bash
+# Run specific test file
+pytest tests/commands/hash/test_your_command.py -v
+
+# Run all tests in a category
+pytest tests/commands/hash/ -v
+
+# Run all tests
+pytest tests/ -v
+```
+
+Follow this structure and you'll have a well-integrated Redis command that follows the package's conventions and patterns.

+### Redis Streams
+
+Redis Streams provide a powerful data structure for handling real-time data. The SDK supports all stream commands:
+
+```python
+from upstash_redis import Redis
+
+redis = Redis.from_env()
+
+# Add entries to a stream
+entry_id = redis.xadd("mystream", "*", {"field1": "value1", "field2": "value2"})
+print(f"Added entry: {entry_id}")
+
+# Read from stream
+messages = redis.xread({"mystream": "0-0"})
+print(f"Messages: {messages}")
+
+# Create consumer group
+redis.xgroup_create("mystream", "mygroup", "$")
+
+# Read as part of consumer group  
+messages = redis.xreadgroup("mygroup", "consumer1", {"mystream": ">"})
+
+# Acknowledge processed messages
+if messages:
+    message_ids = [msg[0] for msg in messages[0][1]]
+    redis.xack("mystream", "mygroup", *message_ids)
+
+# Get stream length
+length = redis.xlen("mystream")
+print(f"Stream length: {length}")
+```
+
+For async usage:
+
+```python
+from upstash_redis.asyncio import Redis
+
+redis = Redis.from_env()
+
+async def stream_example():
+    # Add entries to a stream
+    entry_id = await redis.xadd("mystream", "*", {"user": "alice", "action": "login"})
+    
+    # Read from stream
+    messages = await redis.xread({"mystream": "0-0"})
+    
+    # Consumer group operations
+    await redis.xgroup_create("mystream", "processors", "$")
+    messages = await redis.xreadgroup("processors", "worker1", {"mystream": ">"})
+```
+
 ### Custom commands
 If you want to run a command that hasn't been implemented, you can use the `execute` function of your client instance
 and pass the command as a `list`.
