+### Upload files via AzureMachineLearningFileSystem
+
+```python
+from azureml.fsspec import AzureMachineLearningFileSystem
+# instantiate file system using following URI
+fs = AzureMachineLearningFileSystem('azureml://subscriptions/<subid>/resourcegroups/<rgname>/workspaces/<workspace_name>/datastore/datastorename')
+
+fs.upload(lpath='./data/upload_files/crime-spring.csv', rpath=f'data/fsspec', recursive=False, **{'overwrite': True})
+fs.upload(lpath='./data/upload_folder/', rpath=f'data/fsspec_folder', recursive=True, **{'overwrite': True})
+
+```
+
+### Download files via AzureMachineLearningFileSystem
+```python
+# you can specify recursive as False to download a file
+fs.download(rpath=f'data/fsspec/crime-spring.csv', lpath='./data/download_files/, recursive=False)
+
+# you need to specify recursive as True to download a folder
+fs.download(rpath=f'data/fsspec_folder', lpath=f'./data/download_folder/', recursive=True)

 ### Examples
 
 In this section we provide some examples of how to use Filesystem spec, for some common scenarios.
