-### Guidelines for a speedy merge
+Unit tests
 
-- **Do** 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.
+  * Create a config entry called `TestRemote` for the unit tests to use
-- **Do** use rclone's Client or Transport from [fs/fshttp](https://pkg.go.dev/github.com/rclone/rclone/fs/fshttp) if your backend is HTTP based - this adds features like `--dump bodies`, `--tpslimit`, `--user-agent` without you having to code anything!
+  * Create a `backend/remote/remote_test.go` - copy and adjust your example remote
-- **Do** follow your example backend exactly - use the same code order, function names, layout, structure. **Don't** move stuff around and **Don't** delete the comments.
+  * Make sure all tests pass with `go test -v`
-- **Do not** split your backend up into `fs.go` and `object.go` (there are a few backends like that - don't follow them!)
-- **Do** put your API type definitions in a separate file - by preference `api/types.go`
-- **Remember** we have >50 backends to maintain so keeping them as similar as possible to each other is a high priority!

-## Adding a new s3 provider
+## Writing a plugin ##
-
-It is quite easy to add a new S3 provider to rclone.
-
-You'll need to modify the following files
-
-- `backend/s3/s3.go`
-    - Add the provider to `providerOption` at the top of the file
-    - Add endpoints and other config for your provider gated on the provider in `fs.RegInfo`.
-    - Exclude your provider from generic config questions (eg `region` and `endpoint).
-    - Add the provider to the `setQuirks` function - see the documentation there.
-- `docs/content/s3.md`
-    - Add the provider at the top of the page.
-    - Add a section about the provider linked from there.
-    - Add a transcript of a trial `rclone config` session
-        - Edit the transcript to remove things which might change in subsequent versions
-    - **Do not** alter or add to the autogenerated parts of `s3.md`
-    - **Do not** run `make backenddocs` or `bin/make_backend_docs.py s3`
-- `README.md` - this is the home page in github
-    - Add the provider and a link to the section you wrote in `docs/contents/s3.md`
-- `docs/content/_index.md` - this is the home page of rclone.org
-    - Add the provider and a link to the section you wrote in `docs/contents/s3.md`
-
-When adding the provider, endpoints, quirks, docs etc keep them in
-alphabetical order by `Provider` name, but with `AWS` first and
-`Other` last.
-
-Once you've written the docs, run `make serve` and check they look OK
-in the web browser and the links (internal and external) all work.
-
-Once you've written the code, test `rclone config` works to your
-satisfaction, and check the integration tests work `go test -v -remote
-NewS3Provider:`. You may need to adjust the quirks to get them to
-pass. Some providers just can't pass the tests with control characters
-in the names so if these fail and the provider doesn't support
-`urlEncodeListings` in the quirks then ignore them. Note that the
-`SetTier` test may also fail on non AWS providers.
-
-For an example of adding an s3 provider see [eb3082a1](https://github.com/rclone/rclone/commit/eb3082a1ebdb76d5625f14cedec3f5154a5e7b10).

 New features (backends, commands) can also be added "out-of-tree", through Go plugins.
