+### SeaweedFS ###
+
+[SeaweedFS](https://github.com/chrislusf/seaweedfs/) is a distributed storage system for 
+blobs, objects, files, and data lake, with O(1) disk seek and a scalable file metadata store.
+It has an S3 compatible object storage interface.
+
+Assuming the SeaweedFS are configured with `weed shell` as such:
+```
+> s3.bucket.create -name foo
+> s3.configure -access_key=any -secret_key=any -buckets=foo -user=me -actions=Read,Write,List,Tagging,Admin -apply
+{
+  "identities": [
+    {
+      "name": "me",
+      "credentials": [
+        {
+          "accessKey": "any",
+          "secretKey": "any"
+        }
+      ],
+      "actions": [
+        "Read:foo",
+        "Write:foo",
+        "List:foo",
+        "Tagging:foo",
+        "Admin:foo"
+      ]
+    }
+  ]
+}
+```
+
+To use rclone with SeaweedFS, above configuration should end up with something like this in
+your config:
+
+```
+[seaweedfs_s3]
+type = s3
+provider = SeaweedFS
+access_key_id = any
+secret_access_key = any
+endpoint = localhost:8333
+```
+
+So once set up, for example to copy files into a bucket
+
+```
+rclone copy /path/to/files seaweedfs_s3:foo
+```
+
