+  Creates a new object inside a specified bucket
+---
+
+# google\_storage\_bucket\_object
+
+Creates a new object inside an exisiting bucket in Google cloud storage service (GCS). Currently, it does not support creating custom ACLs. For more information see [the official documentation](https://cloud.google.com/storage/docs/overview) and [API](https://cloud.google.com/storage/docs/json_api).
+
+
+## Example Usage
+
+Example creating a public object in an existing `image-store` bucket.
+
+```
+resource "google_storage_bucket_object" "picture" {
+	name = "butterfly01"
+    source = "/images/nature/garden-tiger-moth.jpg"
+    bucket = "image-store"
+	predefined_acl = "publicRead"
+}
+
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of the object.
+* `bucket` - (Required) The name of the containing bucket.
+* `source` - (Required) A path to the data you want to upload.
+* `predefined_acl` - (Optional, Default: 'projectPrivate') The [canned GCS ACL](https://cloud.google.com/storage/docs/access-control#predefined-acl) apply.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `md5hash` - (Computed) Base 64 MD5 hash of the uploaded data.
+* `crc32c` - (Computed) Base 64 CRC32 hash of the uploaded data.
