## S3
-*Coming soon*
+### Using Minio SDK
+
+First install the SDK:
+
+```bash
+pip3 install minio
+```
+
+Then instantiate a client object using garage root domain, api key and secret:
+
+```python
+import minio
+
+client = minio.Minio(
+ "your.domain.tld",
+ "GKyourapikey",
+ "abcd[...]1234",
+ # Force the region, this is specific to garage
+ region="region",
+)
+```
-Some refs:
- - Minio SDK
- - [Reference](https://docs.min.io/docs/python-client-api-reference.html)
+Then use all the standard S3 endpoints as implemented by the Minio SDK:
+
+```
+# List buckets
+print(client.list_buckets())
+
+# Put an object containing 'content' to /path in bucket named 'bucket':
+content = b"content"
+client.put_object(
+ "bucket",
+ "path",
+ io.BytesIO(content),
+ len(content),
+)
+
+# Read the object back and check contents
+data = client.get_object("bucket", "path").read()
+assert data == content
+```
+
+For further documentation, see the Minio SDK
+[Reference](https://docs.min.io/docs/python-client-api-reference.html)
