-# Rclone Code of Conduct
-
-Like the technical community as a whole, the Rclone team and community
-is made up of a mixture of professionals and volunteers from all over
-the world, working on every aspect of the mission - including
-mentorship, teaching, and connecting people.
-
-Diversity is one of our huge strengths, but it can also lead to
-communication issues and unhappiness. To that end, we have a few
-ground rules that we ask people to adhere to. This code applies
-equally to founders, mentors and those seeking help and guidance.
-
-This isn't an exhaustive list of things that you can't do. Rather,
-take it in the spirit in which it's intended - a guide to make it
-easier to enrich all of us and the technical communities in which we
-participate.
-
-This code of conduct applies to all spaces managed by the Rclone
-project or Rclone Services Ltd. This includes the issue tracker, the
-forum, the GitHub site, the wiki, any other online services or
-in-person events. In addition, violations of this code outside these
-spaces may affect a person's ability to participate within them.
-
-- **Be friendly and patient.**
-- **Be welcoming.** We strive to be a community that welcomes and
-  supports people of all backgrounds and identities. This includes,
-  but is not limited to members of any race, ethnicity, culture,
-  national origin, colour, immigration status, social and economic
-  class, educational level, sex, sexual orientation, gender identity
-  and expression, age, size, family status, political belief,
-  religion, and mental and physical ability.
-- **Be considerate.** Your work will be used by other people, and you
-  in turn will depend on the work of others. Any decision you take
-  will affect users and colleagues, and you should take those
-  consequences into account when making decisions. Remember that we're
-  a world-wide community, so you might not be communicating in someone
-  else's primary language.
-- **Be respectful.** Not all of us will agree all the time, but
-  disagreement is no excuse for poor behavior and poor manners. We
-  might all experience some frustration now and then, but we cannot
-  allow that frustration to turn into a personal attack. It's
-  important to remember that a community where people feel
-  uncomfortable or threatened is not a productive one. Members of the
-  Rclone community should be respectful when dealing with other
-  members as well as with people outside the Rclone community.
-- **Be careful in the words that you choose.** We are a community of
-  professionals, and we conduct ourselves professionally. Be kind to
-  others. Do not insult or put down other participants. Harassment and
-  other exclusionary behavior aren't acceptable. This includes, but is
-  not limited to:
-  - Violent threats or language directed against another person.
-  - Discriminatory jokes and language.
-  - Posting sexually explicit or violent material.
-  - Posting (or threatening to post) other people's personally
-    identifying information ("doxing").
-  - Personal insults, especially those using racist or sexist terms.
-  - Unwelcome sexual attention.
-  - Advocating for, or encouraging, any of the above behavior.
-  - Repeated harassment of others. In general, if someone asks you to
-    stop, then stop.
-- **When we disagree, try to understand why.** Disagreements, both
-  social and technical, happen all the time and Rclone is no
-  exception. It is important that we resolve disagreements and
-  differing views constructively. Remember that we're different. The
-  strength of Rclone comes from its varied community, people from a
-  wide range of backgrounds. Different people have different
-  perspectives on issues. Being unable to understand why someone holds
-  a viewpoint doesn't mean that they're wrong. Don't forget that it is
-  human to err and blaming each other doesn't get us anywhere.
-  Instead, focus on helping to resolve issues and learning from
-  mistakes.
-
-If you believe someone is violating the code of conduct, we ask that
-you report it by emailing [info@rclone.com](mailto:info@rclone.com).

 (Note that you can also replace `go build` with `make`, which will include a
 more accurate version number in the executable as well as enable you to specify
 more build options.) Finally make a branch to add your new feature
 
-```sh
-git checkout -b my-new-feature

-## Writing Documentation
+## Writing Documentation ##
 
 If you are adding a new feature then please update the documentation.
 
-The documentation sources are generally in Markdown format, in conformance
-with the CommonMark specification and compatible with GitHub Flavored
-Markdown (GFM). The markdown format is checked as part of the lint operation
-that runs automatically on pull requests, to enforce standards and consistency.
-This is based on the [markdownlint](https://github.com/DavidAnson/markdownlint)
-tool, which can also be integrated into editors so you can perform the same
-checks while writing.
-
-HTML pages, served as website <rclone.org>, are generated from the Markdown,
-using [Hugo](https://gohugo.io). Note that when generating the HTML pages,
-there is currently used a different algorithm for generating header anchors
-than what GitHub uses for its Markdown rendering. For example, in the HTML docs
-generated by Hugo any leading `-` characters are ignored, which means when
-linking to a header with text `--config string` we therefore need to use the
-link `#config-string` in our Markdown source, which will not work in GitHub's
-preview where `#--config-string` would be the correct link.
-
-Most of the documentation are written directly in text files with extension
-`.md`, mainly within folder `docs/content`. Note that several of such files
-are autogenerated (e.g. the command documentation, and `docs/content/flags.md`),
-or contain autogenerated portions (e.g. the backend documentation under
-`docs/content/commands`). These are marked with an `autogenerated` comment.
-The sources of the autogenerated text are usually Markdown formatted text
-embedded as string values in the Go source code, so you need to locate these
-and edit the `.go` file instead. The `MANUAL.*`, `rclone.1` and other text
-files in the root of the repository are also autogenerated. The autogeneration
-of files, and the website, will be done during the release process. See the
-`make doc` and `make website` targets in the Makefile if you are interested in
-how. You don't need to run these when adding a feature.

-- **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.
-- **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!
-- **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!

-## Adding a new s3 provider
+## Writing a plugin ##
 
-It is quite easy to add a new S3 provider to rclone.
+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.
 
-You'll need to modify the following files
+Usage
 
-- `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.
-    - Make sure this is in alphabetical order in the `Providers` section.
-  - 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`
+ - Naming
+   - Plugins names must have the pattern `librcloneplugin_KIND_NAME.so`.
+   - `KIND` should be one of `backend`, `command` or `bundle`.
+   - Example: A plugin with backend support for PiFS would be called
+     `librcloneplugin_backend_pifs.so`.
+ - Loading
+   - Supported on macOS & Linux as of now. ([Go issue for Windows support](https://github.com/golang/go/issues/19282))
+   - Supported on rclone v1.50 or greater.
+   - All plugins in the folder specified by variable `$RCLONE_PLUGIN_PATH` are loaded.
+   - If this variable doesn't exist, plugin support is disabled.
+   - Plugins must be compiled against the exact version of rclone to work.
+     (The rclone used during building the plugin must be the same as the source of rclone)
 
-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).

-### Building
+Building
 
 To turn your existing additions into a Go plugin, move them to an external repository
 and change the top-level package name to `main`.
 
-Check `rclone --version` and make sure that the plugin's rclone dependency and
-host Go version match.
+Check `rclone --version` and make sure that the plugin's rclone dependency and host Go version match.
 
 Then, run `go build -buildmode=plugin -o PLUGIN_NAME.so .` to build the plugin.

-## Keeping a backend or command out of tree
-
-Rclone was designed to be modular so it is very easy to keep a backend
-or a command out of the main rclone source tree.
-
-So for example if you had a backend which accessed your proprietary
-systems or a command which was specialised for your needs you could
-add them out of tree.
-
-This may be easier than using a plugin and is supported on all
-platforms not just macOS and Linux.
-
-This is explained further in <https://github.com/rclone/rclone_out_of_tree_example>
-which has an example of an out of tree backend `ram` (which is a
-renamed version of the `memory` backend).

+## Triaging Tickets ##
 
-When a ticket comes in it should be triaged.  This means it should be classified

-remain without labels or milestone for a while.
+When a ticket comes in it should be triaged.  This means it should be classified by adding labels and placed into a milestone. Quite a lot of tickets need a bit of back and forth to determine whether it is a valid ticket so tickets may remain without labels or milestone for a while.
 
 Rclone uses the labels like this:
 
-- `bug` - a definitely verified bug
-- `can't reproduce` - a problem which we can't reproduce
-- `doc fix` - a bug in the documentation - if users need help understanding the
-  docs add this label
-- `duplicate` - normally close these and ask the user to subscribe to the original
-- `enhancement: new remote` - a new rclone backend
-- `enhancement` - a new feature
-- `FUSE` - to do with `rclone mount` command
-- `good first issue` - mark these if you find a small self-contained issue -
-  these get shown to new visitors to the project
-- `help` wanted - mark these if you find a self-contained issue - these get
-  shown to new visitors to the project
-- `IMPORTANT` - note to maintainers not to forget to fix this for the release
-- `maintenance` - internal enhancement, code re-organisation, etc.
-- `Needs Go 1.XX` - waiting for that version of Go to be released
-- `question` - not a `bug` or `enhancement` - direct to the forum for next time
-- `Remote: XXX` - which rclone backend this affects
-- `thinking` - not decided on the course of action yet

 ## Making a manual build of docker
 
-To do a basic build of rclone's docker image to debug builds locally:
+The rclone docker image should autobuild on via GitHub actions.  If it doesn't
+or needs to be updated then rebuild like this.
 
-```sh
-docker buildx build --load -t rclone/rclone:testing --progress=plain .
-docker run --rm rclone/rclone:testing version
+See: https://github.com/ilteoood/docker_buildx/issues/19
+See: https://github.com/ilteoood/docker_buildx/blob/master/scripts/install_buildx.sh
+
+```
+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
+docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
+SUPPORTED_PLATFORMS=$(docker buildx inspect --bootstrap | grep 'Platforms:*.*' | cut -d : -f2,3)
+echo "Supported platforms: $SUPPORTED_PLATFORMS"
+docker buildx build --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7 -t rclone/rclone:1.54.1 -t rclone/rclone:1.54 -t rclone/rclone:1 -t rclone/rclone:latest --push .
+docker buildx stop actions_builder
 ```
 
-To test the multipatform build
+### Old build for linux/amd64 only
 
-```sh
-docker buildx build -t rclone/rclone:testing --progress=plain --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6 .
 ```
-
-To make a full build then set the tags correctly and add `--push`
-
-Note that you can't only build one architecture - you need to build them all.
-
-```sh
-docker buildx build --platform linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6 -t rclone/rclone:1.54.1 -t rclone/rclone:1.54 -t rclone/rclone:1 -t rclone/rclone:latest --push .
