 - **Per-Step Agents**: Configure different agents with roles, goals, tools for each step
 - **Async Execution**: Use `aexecute()` for async workflows
 - **Planning Mode**: Enable at workflow level with `planning=True`
+- **Branching**: Use `next_steps` and `branch_condition` for conditional routing
+- **Loops**: Use `loop_over` and `loop_var` to iterate over data
+
+### Simple Workflow (Recommended)
+
+The easiest way to create workflows - just pass functions as steps:
+
+```python
+from praisonaiagents import Workflow, WorkflowContext, StepResult
+
+# Define simple handler functions
+def validate(ctx: WorkflowContext) -> StepResult:
+    if not ctx.input:
+        return StepResult(output="No input", stop_workflow=True)
+    return StepResult(output=f"Valid: {ctx.input}")
+
+def process(ctx: WorkflowContext) -> StepResult:
+    return StepResult(output=f"Processed: {ctx.previous_result}")
+
+# Create and run workflow
+workflow = Workflow(steps=[validate, process])
+result = workflow.start("Hello World", verbose=True)
+print(result["output"])  # "Processed: Valid: Hello World"
+```
+
+**Key Features:**
+- **Just pass functions** - No complex configuration needed
+- **Early stop** - Return `stop_workflow=True` to stop the workflow
+- **Context passing** - Access `ctx.input`, `ctx.previous_result`, `ctx.variables`
+- **Verbose mode** - See step-by-step progress
+
+### Workflow Branching & Loops
+
+```python
+from praisonaiagents import WorkflowStep
+
+# Branching step
+decision_step = WorkflowStep(
+    name="decide",
+    action="Evaluate if task is complete",
+    next_steps=["success_step", "retry_step"],
+    branch_condition={"success": ["success_step"], "failure": ["retry_step"]}
+)
+
+# Loop step
+loop_step = WorkflowStep(
+    name="process_items",
+    action="Process {{item}}",
+    loop_over="items",  # Variable containing list
+    loop_var="item"     # Current item variable name
+)
+```
+
+### Task Callbacks & Variables (process="workflow")
+
+```python
+from praisonaiagents import Agent, Task, PraisonAIAgents
+
+# Per-task agent config (no need to create agent separately)
+task = Task(
+    description="Research {{topic}}",
+    agent_config={"name": "Researcher", "role": "Expert", "llm": "gpt-4o-mini"},
+    variables={"topic": "AI trends"}
+)
+
+# Callbacks for workflow execution
+def on_start(task, task_id):
+    print(f"Starting: {task.name}")
+
+def on_complete(task, output):
+    print(f"Completed: {task.name}")
+
+agents = PraisonAIAgents(
+    agents=[agent],

+    process="workflow",
+    on_task_start=on_start,

 - **Per-Step Agents**: Configure different agents with roles, goals, tools for each step
 - **Async Execution**: Use `aexecute()` for async workflows
 - **Planning Mode**: Enable at workflow level with `planning=True`
+- **Branching**: Use `next_steps` and `branch_condition` for conditional routing
+- **Loops**: Use `loop_over` and `loop_var` to iterate over data
+
+### Simple Workflow (Recommended)
+
+The easiest way to create workflows - just pass functions as steps:
+
+```python
+from praisonaiagents import Workflow, WorkflowContext, StepResult
+
+# Define simple handler functions
+def validate(ctx: WorkflowContext) -> StepResult:
+    if not ctx.input:
+        return StepResult(output="No input", stop_workflow=True)
+    return StepResult(output=f"Valid: {ctx.input}")
+
+def process(ctx: WorkflowContext) -> StepResult:
+    return StepResult(output=f"Processed: {ctx.previous_result}")
+
+# Create and run workflow
+workflow = Workflow(steps=[validate, process])
+result = workflow.start("Hello World", verbose=True)
+print(result["output"])  # "Processed: Valid: Hello World"
+```
+
+**Key Features:**
+- **Just pass functions** - No complex configuration needed
+- **Early stop** - Return `stop_workflow=True` to stop the workflow
+- **Context passing** - Access `ctx.input`, `ctx.previous_result`, `ctx.variables`
+- **Verbose mode** - See step-by-step progress
+
+### Workflow Branching & Loops
+
+```python
+from praisonaiagents import WorkflowStep
+
+# Branching step
+decision_step = WorkflowStep(
+    name="decide",
+    action="Evaluate if task is complete",
+    next_steps=["success_step", "retry_step"],
+    branch_condition={"success": ["success_step"], "failure": ["retry_step"]}
+)
+
+# Loop step
+loop_step = WorkflowStep(
+    name="process_items",
+    action="Process {{item}}",
+    loop_over="items",  # Variable containing list
+    loop_var="item"     # Current item variable name
+)
+```
+
+### Task Callbacks & Variables (process="workflow")
+
+```python
+from praisonaiagents import Agent, Task, PraisonAIAgents
+
+# Per-task agent config (no need to create agent separately)
+task = Task(
+    description="Research {{topic}}",
+    agent_config={"name": "Researcher", "role": "Expert", "llm": "gpt-4o-mini"},
+    variables={"topic": "AI trends"}
+)
+
+# Callbacks for workflow execution
+def on_start(task, task_id):
+    print(f"Starting: {task.name}")
+
+def on_complete(task, output):
+    print(f"Completed: {task.name}")
+
+agents = PraisonAIAgents(
+    agents=[agent],
+    tasks=[task],
+    process="workflow",
+    on_task_start=on_start,
