+### Guidelines for a speedy merge
 
-  * 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!

+- **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.
+- **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!

-  * Create a config entry called `TestRemote` for the unit tests to use

-## Writing a plugin ##
+## Adding a new s3 provider
+
+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).
+
+## Writing a plugin
 
 New features (backends, commands) can also be added "out-of-tree", through Go plugins.
 Changes will be kept in a dynamically loaded file instead of being compiled into the main binary.
 This is useful if you can't merge your changes upstream or don't want to maintain a fork of rclone.

 ## Making a manual build of docker

-or needs to be updated then rebuild like this.

-See: https://github.com/ilteoood/docker_buildx/issues/19
-See: https://github.com/ilteoood/docker_buildx/blob/master/scripts/install_buildx.sh
+To do a basic build of rclone's docker image to debug builds locally:
 
 ```
-git co v1.54.1
-docker pull golang
-export DOCKER_CLI_EXPERIMENTAL=enabled
-docker buildx create --name actions_builder --use
-docker run --rm --privileged docker/binfmt:820fdd95a9972a5308930a2bdfb8573dd4447ad3
