+# Development Bucket
+
+To create a bucket for development that can be used by all origins we need to enable CORS for the bucket. First create the bucket and some access keys then download the `b2-windows.exe` tool from the website.
+
+First login using the keys:
+
+```powershell
+b2 authorize-account <accountId> <applicationKey>
+```
+
+Next lets set the cors rules for the bucket:
+
+```powershell
+$rules =
+@'
+[
+  {
+    "corsRuleName": "allowall-s3",
+    "allowedOrigins": ["*"],
+    "allowedHeaders": ["*"],
+    "allowedOperations": [
+        "s3_get",
+        "s3_put",
+        "s3_head",
+        "s3_delete"
+    ],
+    "exposeHeaders": ["ETag", "x-amz-server-side-encryption", "x-amz-request-id"],
+    "maxAgeSeconds": 3600
+  }
+]
+'@
+b2 update-bucket --cors-rules $rules <bucketName>
+```
