+### Async Aryn DocParse
+
+#### Single Job Example
+```python
+import time
+from aryn_sdk.partition import partition_file_submit_async, partition_file_result_async
+
+with open("my-favorite-pdf.pdf", "rb") as f:
+    job = partition_file_submit_async(
+        f,
+        use_ocr=True,
+        extract_table_structure=True,
+    )
+
+job_id = job["job_id"]
+
+# Poll for the results
+result = partition_file_result_async(job_id)
+while result.status == JobStatus.IN_PROGRESS:
+    time.sleep(5)
+    result = partition_file_result_async(job_id)
+```
+
+#### Multi-Job Example
+
+```python
+import logging
+import time
+from aryn_sdk.partition import partition_file_submit_async, partition_file_result_async, PartitionError
+
+files = [open("file1.pdf", "rb"), open("file2.docx", "rb")]
+job_ids = {}
+for i, f in enumerate(files):
+    try:
+        job_ids[i] = partition_file_submit_async(f))
+    except Exception as e:
+        logging.warning(f"Failed to submit {f}: {e}")
+
+results = {}
+for i, job_id in job_ids.items():
+    result = partition_file_result_async(job_id)
+    while result.status == JobStatus.IN_PROGRESS:
+        time.sleep(5)
+        result = partition_file_result_async(job_id)
+    results[i] = result
+```
+
+#### Cancelling an async job
+
+```python
+from aryn_sdk.partition import partition_file_submit_async, cancel_async_partition_job
+        job_id = partition_file_submit_async(
+                    "path/to/file.pdf",
+                    use_ocr=True,
+                    extract_table_structure=True,
+                    extract_images=True,
+                )["job_id"]
+
+        cancel_async_partition_job(job_id)
