+## Workflows
+
+### Defining Steps
+
+- Define a workflow step using `NewStep` and `StepParams`.
+- Each step requires a `Name`, `Identifier`, and a `Handler` function.
+- The `Handler` function processes the job and returns a result and the next step (if any).
+
+```go
+lastStep := NewStep(&StepParams{
+    Name:        "Last step",
+    Identifier:  "last_step",
+    Description: "Last step",
+    Client:      client,
+    MaxRetries:  3,
+    Handler: func(ctx context.Context, currentStep *Step, job queue.GeneralQueueJob) (queue.GeneralQueueHandlerResult, *Step, error) {
+        return queue.GeneralQueueHandlerResult{
+            ResultPayload: map[string]interface{}{
+                "lastStep": "hello",
+            },
+        }, nil, nil
+    },
+})
+
+firstStep := NewStep(&StepParams{
+    Name:        "Initial step",
+    Identifier:  "initial_step",
+    Description: "Initial step",
+    Client:      client,
+    MaxRetries:  3,
+    Handler: func(ctx context.Context, currentStep *Step, job queue.GeneralQueueJob) (queue.GeneralQueueHandlerResult, *Step, error) {
+        return queue.GeneralQueueHandlerResult{
+            ResultPayload: map[string]interface{}{
+                "firstStep": "hello",
+            },
+        }, lastStep, nil // Return the next step to execute
+    },
+})
+```
+
+### Creating Workflows
+
+- Define a workflow using `NewWorkflow`, providing a name, identifier, starting step, and all steps in the workflow.
+
+```go
+w := NewWorkflow("Example", "example", firstStep, []*Step{firstStep, lastStep})
+```
+
+### Executing Workflows
+
+- To start a workflow, call the `Execute` method with an initial payload.
+- A unique `workflowId` is automatically generated and passed through each step.
+
+```go
+err := workflow.Execute(ctx, map[string]interface{}{
+    "input": "start data",
+})
+```
+
+### Scheduled Workflows
+
+- Use `NewCronTrigger` to run a workflow at regular intervals.
+
+```go
+NewCronTrigger(ctx, workflow, 1 * time.Hour)
+```
+
