+  * Please use [lib/rest](https://pkg.go.dev/github.com/rclone/rclone/lib/rest) if you are implementing a REST like backend and parsing XML/JSON in the backend. It makes maintenance much easier.
+  * If your backend is HTTP based then please use rclone's Client or Transport from [fs/fshttp](https://pkg.go.dev/github.com/rclone/rclone/fs/fshttp) - this adds features like `--dump bodies`, `--tpslimit`, `--user-agent` without you having to code anything!
