+### Export
+
+Certain task needs to set the workflow context to save the task output for later usage. Users set the content of the context through a runtime expression. The result of the expression is the new value of the context. The expression is evaluated against the existing context. 
+
+Optionally, the context might have an associated schema. 
+
+#### Properties
+
+| Property | Type | Required | Description |
+|----------|:----:|:--------:|-------------|
+| schema | [`schema`](#schema) | `no` | The [`schema`](#schema) used to describe and validate context.<br>*Included to handle the non frequent case in which the context has a known format.* |
+| as | `string`<br>`object` | `no` | A runtime expression, if any, used to export the output data to the context. |
+
+#### Examples
+
+Merge the task output into the current context. 
+
+```yaml
+as: '.+$output'
+```
+
+Replace the context with the task output. 
+
+```yaml
+as: $output
+```

 ### Schema
 
 Describes a data schema.
