 # Garage Admin SDK
 
-## Clone this repo
+## For SDK users
+
+The SDK is currently only available for Python.
+
+### Python
+
+You need at least Python 3.6, pip, and setuptools.
+Because the python package is in a subfolder, the command is a bit more complicated than usual:
+
+```bash
+pip3 install --user 'git+https://git.deuxfleurs.fr/quentin/garage-admin-sdk#egg=garage-admin-sdk&subdirectory=python'
+```
+
+Now, let imagine you have a fresh Garage instance running on localhost, with the admin API configured on port 3903 with the bearer `s3cr3t`:
+
+```python
+import garage_admin_sdk
+from garage_admin_sdk.api import nodes_api, layout_api, key_api
+from garage_admin_sdk.model.node_cluster_info import NodeClusterInfo
+from garage_admin_sdk.model.layout_version import LayoutVersion
+from garage_admin_sdk.model.add_key_request import AddKeyRequest
+from garage_admin_sdk.model.update_key_request import UpdateKeyRequest
+from garage_admin_sdk.model.update_key_request_allow import UpdateKeyRequestAllow
+
+configuration = garage_admin_sdk.Configuration(
+    host = "http://localhost:3903/v0",
+    access_token = "s3cr3t"
+)
+
+with garage_admin_sdk.ApiClient(configuration) as api:
+    # Init APIs
+    nodes = nodes_api.NodesApi(api)
+    layout = layout_api.LayoutApi(api)
+    keys = key_api.KeyApi(api)
+
+    # Display some info on the node
+    status = nodes.get_nodes()
+    print(f"running garage {status.garage_version}, node_id {status.node}")
+
+    # Change layout of this node
+    current = layout.get_layout()
+    layout.add_layout(request_body={
+        f"{status.node}": NodeClusterInfo(
+            zone = "dc1",
+            capacity = 1,
+            tags = [ "dev" ],
+        )
+    })
+    layout.apply_layout(layout_version=LayoutVersion(
+        version = current.version + 1
+    ))
+
+    # Create key, allow it to create buckets
+    kreq = AddKeyRequest(name="openapi")
+    kinfo = keys.add_key(add_key_request=kreq)
+
+    allow_create = UpdateKeyRequestAllow(create_bucket=True)
+    kreq = UpdateKeyRequest(allow=allow_create)
+    keys.update_key(kinfo.access_key_id, update_key_request=kreq)
+
+    # Display key
+    print(f"your cluster is ready, your key id: {kinfo.access_key_id}, your secret key: {kinfo.secret_access_key}")
+```
+
+*This example is named `short.py` in the example folder. Other python examples are also available.*
+
+See also:
+ - [examples](./example)
+ - [generated doc](./python)
+
+## For SDK developpers
+
+PR are accepted for other languages as soon as meaningful, manually written, covering
+a large range of the API are provided. Thanks in advance :-)
