-# 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).

+getting started docs](https://golang.org/doc/install) for more info.
+
+First in your web browser press the fork button on [rclone's GitHub
 page](https://github.com/rclone/rclone).
 
-Then [install Git](https://git-scm.com/downloads) and set your public contribution
-[name](https://docs.github.com/en/github/getting-started-with-github/setting-your-username-in-git)
-and [email](https://docs.github.com/en/github/setting-up-and-managing-your-github-user-account/setting-your-commit-email-address#setting-your-commit-email-address-in-git).
+Now in your terminal
 
-Next open your terminal, change directory to your preferred folder and initialise
-your local rclone project:
+    git clone https://github.com/rclone/rclone.git
+    cd rclone
+    git remote rename origin upstream
+    git remote add origin git@github.com:YOURUSER/rclone.git
+    go build
 
-```console
-git clone https://github.com/rclone/rclone.git
-cd rclone
-git remote rename origin upstream
-  # if you have SSH keys setup in your GitHub account:
-git remote add origin git@github.com:YOURUSER/rclone.git
-  # otherwise:
-git remote add origin https://github.com/YOURUSER/rclone.git
-```
+Make a branch to add your new feature
 
-Note that most of the terminal commands in the rest of this guide must be
-executed from the rclone folder created above.
-
-Now [install Go](https://golang.org/doc/install) and verify your installation:
-
-```console
-go version
-```
-
-Great, you can now compile and execute your own version of rclone:
-
-```console
-go build
-./rclone version
-```
-
-(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
-
-```console
-git checkout -b my-new-feature
-```

-
-Follow the guideline for [commit messages](#commit-messages) and then:
-
-```console
-git checkout my-new-feature      # To switch to your branch
-git status                       # To see the new and changed files

+If so, then make the changes in the same branch, squash the commits (make multiple commits one commit) by running:
+```
+git log # See how many commits you want to squash
+git reset --soft HEAD~2 # This squashes the 2 latest commits together.

-You can modify the message or changes in the latest commit using:
+## CI for your fork ##
 
-```console
-git commit --amend
-```
+rclone currently uses [GitHub Actions](https://github.com/rclone/rclone/actions) to build and test the project, which should be automatically available for your fork too from the `Actions` tab in your repository.
 
-If you amend to commits that have been pushed to GitHub, then you will have to
-[replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Replacing your previously pushed commits
-
-Note that you are about to rewrite the GitHub history of your branch. It is good
-practice to involve your collaborators before modifying commits that have been
-pushed to GitHub.
-
-Your previously pushed commits are replaced by:

-### Basing your changes on the latest master
-
-To base your changes on the latest version of the
-[rclone master](https://github.com/rclone/rclone/tree/master) (upstream):

-git push origin --follow-tags    # optional update of your fork in GitHub
-git checkout my-new-feature
-git rebase master
-```
-
-If you rebase commits that have been pushed to GitHub, then you will have to

-### Squashing your commits
-
-To combine your commits into one commit:
-
-```console
-git log                          # To count the commits to squash, e.g. the last 2
-git reset --soft HEAD~2          # To undo the 2 latest commits
-git status                       # To check everything is as expected
-```
-
-If everything is fine, then make the new combined commit:
-
-```console
-git commit                       # To commit the undone commits as one
-```
-
-otherwise, you may roll back using:
-
-```console
-git reflog                       # To check that HEAD{1} is your previous state
-git reset --soft 'HEAD@{1}'      # To roll back to your previous state
-```
-
-If you squash commits that have been pushed to GitHub, then you will have to

-### GitHub Continuous Integration
-
-rclone currently uses [GitHub Actions](https://github.com/rclone/rclone/actions)
-to build and test the project, which should be automatically available for your
-fork too from the `Actions` tab in your repository.
-
-## Testing
-
-### Code quality tests
-
-If you install [golangci-lint](https://github.com/golangci/golangci-lint) then
-you can run the same tests as get run in the CI which can be very helpful.
-
-You can run them with `make check` or with `golangci-lint run ./...`.
-
-Using these tests ensures that the rclone codebase all uses the same coding
-standards. These tests also check for easy mistakes to make (like forgetting
-to check an error return).
-
-### Quick testing
+## Testing ##
 
 rclone's tests are run from the go testing framework, so at the top
 level you can run this to run all the tests.
 
-```console
-go test -v ./...

-
-You can also use `make`, if supported by your platform
-
-```console
-make quicktest

-## 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 and style 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 by David Anson, which can also be integrated into editors so you can
-perform the same checks while writing. It generally follows Ciro Santilli's
-[Markdown Style Guide](https://cirosantilli.com/markdown-style-guide), which
-is good source if you want to know more.
-
-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.
-
 If you add a new general flag (not for a backend), then document it in
 `docs/content/docs.md` - the flags there are supposed to be in
 alphabetical order.
 
 If you add a new backend option/flag, then it should be documented in
-the source file in the `Help:` field:
+the source file in the `Help:` field.  The first line of this is used
+for the flag help, the remainder is shown to the user in `rclone
+config` and is added to the docs with `make backenddocs`.
 
-- Start with the most important information about the option,
-  as a single sentence on a single line.
-  - This text will be used for the command-line flag help.
-  - It will be combined with other information, such as any default value,
-    and the result will look odd if not written as a single sentence.
-  - It should end with a period/full stop character, which will be shown
-    in docs but automatically removed when producing the flag help.
-  - Try to keep it below 80 characters, to reduce text wrapping in the terminal.
-- More details can be added in a new paragraph, after an empty line (`"\n\n"`).
-  - Like with docs generated from Markdown, a single line break is ignored
-    and two line breaks creates a new paragraph.
-  - This text will be shown to the user in `rclone config`
-    and in the docs (where it will be added by `make backenddocs`,
-    normally run some time before next release).
-- To create options of enumeration type use the `Examples:` field.
-  - Each example value have their own `Help:` field, but they are treated
-    a bit different than the main option help text. They will be shown
-    as an unordered list, therefore a single line break is enough to
-    create a new list item. Also, for enumeration texts like name of
-    countries, it looks better without an ending period/full stop character.
-- You can run `make backenddocs` to verify the resulting Markdown.
-  - This will update the autogenerated sections of the backend docs Markdown
-    files under `docs/content`.
-  - It requires you to have [Python](https://www.python.org) installed.
-  - The `backenddocs` make target runs the Python script `bin/make_backend_docs.py`,
-    and you can also run this directly, optionally with the name of a backend
-    as argument to only update the docs for a specific backend.
-  - **Do not** commit the updated Markdown files. This operation is run as part of
-    the release process. Since any manual changes in the autogenerated sections
-    of the Markdown files will then be lost, we have a pull request check that
-    reports error for any changes within the autogenerated sections. Should you
-    have done manual changes outside of the autogenerated sections they must be
-    committed, of course.
-- You can run `make serve` to verify the resulting website.
-  - This will build the website and serve it locally, so you can open it in
-    your web browser and verify that the end result looks OK. Check specifically
-    any added links, also in light of the note above regarding different algorithms
-    for generated header anchors.
-  - It requires you to have the [Hugo](https://gohugo.io) tool available.
-  - The `serve` make target depends on the `website` target, which runs the
-    `hugo` command from the `docs` directory to build the website, and then
-    it serves the website locally with an embedded web server using a command
-    `hugo server --logLevel info -w --disableFastRender --ignoreCache`, so you
-    can run similar Hugo commands directly as well.
+The only documentation you need to edit are the `docs/content/*.md`
+files.  The `MANUAL.*`, `rclone.1`, web site, etc. are all auto generated
+from those 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.
 
-When writing documentation for an entirely new backend,
-see [backend documentation](#backend-documentation).
+Documentation for rclone sub commands is with their code, e.g.
+`cmd/ls/ls.go`.
 
-If you are updating documentation for a command, you must do that in the
-command source code, e.g. `cmd/ls/ls.go`. Write flag help strings as a single
-sentence on a single line, without a period/full stop character at the end,
-as it will be combined unmodified with other information (such as any default
-value).
+Note that you can use [GitHub's online editor](https://help.github.com/en/github/managing-files-in-a-repository/editing-files-in-another-users-repository)
+for small changes in the docs which makes it very easy.

-### 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.
-- **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!
+  * Create a config entry called `TestRemote` for the unit tests to use
+  * Create a `backend/remote/remote_test.go` - copy and adjust your example remote
+  * Make sure all tests pass with `go test -v`

-- Create a config entry called `TestRemote` for the unit tests to use
-- Create a `backend/remote/remote_test.go` - copy and adjust your example remote
-- Make sure all tests pass with `go test -v`
-
-### Integration tests
-
-- Add your backend to `fstest/test_all/config.yaml`
-  - Once you've done that then you can use the integration test framework from
-    the project root:
-  - `go run ./fstest/test_all -backends remote`

+      * test_all -backends remote
 
 Or if you want to run the integration tests manually:
 
-- Make sure integration tests pass with
-  - `cd fs/operations`
-  - `go test -v -remote TestRemote:`
-  - `cd fs/sync`
-  - `go test -v -remote TestRemote:`
-- If your remote defines `ListR` check with this also
-  - `go test -v -remote TestRemote: -fast-list`

+Add your fs to the docs - you'll need to pick an icon for it from
 [fontawesome](http://fontawesome.io/icons/).  Keep lists of remotes in
 alphabetical order of full name of remote (e.g. `drive` is ordered as
 `Google Drive`) but with the local file system last.
 
-- `README.md` - main GitHub page

-- `docs/content/overview.md` - overview docs - add an entry into the Features
-  table and the Optional Features table.
-- `docs/content/docs.md` - list of remotes in config section
-- `docs/content/_index.md` - front page of rclone.org
-- `docs/layouts/chrome/navbar.html` - add it to the website navigation

 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.
 
-## Adding a new s3 provider
+## Writing a plugin ##
 
-[Please see the guide in the S3 backend directory](backend/s3/README.md).
+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.
 
-## Writing a plugin
+Usage
 
-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.
+ - 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)

-### 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).
+[Minimal example](https://gist.github.com/terorie/21b517ee347828e899e1913efc1d684f)

+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

-## Update dependencies
+Early in the next release cycle update the dependencies
 
-Early in the next release cycle update the dependencies.
-
-- Review any pinned packages in go.mod and remove if possible
-- `make updatedirect`
-- `make GOTAGS=cmount`
-- `make compiletest`
-- Fix anything which doesn't compile at this point and commit changes here
-- `git commit -a -v -m "build: update all dependencies"`
-
-If the `make updatedirect` upgrades the version of go in the `go.mod`
-
-```text
-go 1.22.0
-```
-
-then go to manual mode. `go1.22` here is the lowest supported version
-in the `go.mod`.
-
-If `make updatedirect` added a `toolchain` directive then remove it.
-We don't want to force a toolchain on our users. Linux packagers are
-often using a version of Go that is a few versions out of date.
-
-```console
-go list -m -f '{{if not (or .Main .Indirect)}}{{.Path}}{{end}}' all > /tmp/potential-upgrades
-go get -d $(cat /tmp/potential-upgrades)
-go mod tidy -go=1.22 -compat=1.22
-```
-
-If the `go mod tidy` fails use the output from it to remove the
-package which can't be upgraded from `/tmp/potential-upgrades` when
-done
-
-```console
-git co go.mod go.sum
-```
-
-And try again.
-
-Optionally upgrade the direct and indirect dependencies. This is very
-likely to fail if the manual method was used abve - in that case
-ignore it as it is too time consuming to fix.
-
-- `make update`
-- `make GOTAGS=cmount`
-- `make compiletest`
-- roll back any updates which didn't compile
-- `git commit -a -v --amend`
-- **NB** watch out for this changing the default go version in `go.mod`
-
-Note that `make update` updates all direct and indirect dependencies
-and there can occasionally be forwards compatibility problems with
-doing that so it may be necessary to roll back dependencies to the
-version specified by `make updatedirect` in order to get rclone to
-build.
-
-Once it compiles locally, push it on a test branch and commit fixes
-until the tests pass.
-
-### Major versions
-
-The above procedure will not upgrade major versions, so v2 to v3.
-However this tool can show which major versions might need to be
-upgraded:
-
-```console
-go run github.com/icholy/gomajor@latest list -major
-```
-
-Expect API breakage when updating major versions.
-
-## Tidy beta
-
-At some point after the release run
-
-```console
-bin/tidy-beta v1.55
-```
-
-where the version number is that of a couple ago to remove old beta binaries.

+  * git commit -a -v
 
 ## Making a point release
 
@@ -124,86 +48,57 @@ If rclone needs a point release due to some horrendous bug:
 
 Set vars

-## Sponsor logos
-
-If updating the website note that the sponsor logos have been moved out of the

-
-You will need to checkout `/docs/static/img/logos` from <https://github.com/rclone/third-party-logos>
-which is a private repo containing artwork from sponsors.
-
-## Update the website between releases
-
-Create an update website branch based off the last release
-
-```console
-git co -b update-website
-```
-
-If the branch already exists, double check there are no commits that need saving.
-
-Now reset the branch to the last release
-
-```console
-git reset --hard v1.64.0

-
-Create the changes, check them in, test with `make serve` then

-
-Check out <https://test.rclone.org> and when happy
-
-```console

 ## 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.
 
-```console
-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
 
-```console
-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.
-
-```console
-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 .
