 Now [install Go](https://golang.org/doc/install) and verify your installation:
 
-    go version
+```sh

+```
 
 Great, you can now compile and execute your own version of rclone:
 
-    go build
-    ./rclone version
+```sh
+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
 
-    git checkout -b my-new-feature
+```sh
+git checkout -b my-new-feature

 ### Quick 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.
 
-    go test -v ./...

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

 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!)

+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.
 
 ### Usage
 
- - 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
 
 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

+When a ticket is tagged it should be added to a milestone, either the next
+release, the one after, Soon or Help Wanted.  Bugs can be added to the
+"Known Bugs" milestone if they aren't planned to be fixed or need to wait for
+something (e.g. the next go release).
 
 The milestones have these meanings:
 
-* v1.XX - stuff we would like to fit into this release
-* v1.XX+1 - stuff we are leaving until the next release
-* Soon - stuff we think is a good idea - waiting to be scheduled for a release
-* Help wanted - blue sky stuff that might get moved up, or someone could help with
-* Known bugs - bugs waiting on external factors or we aren't going to fix for the moment

 High impact regressions should be fixed before the next release.
 
-Near the start of the release cycle, the dependencies should be updated with `make update` to give time for bugs to surface.

-- Detects markdown files changed in the last commit.
+- Detects markdown files changed between a commit and one of its ancestors. Default is to

 - Identifies modified autogenerated sections marked by specific comments.
 - Reports violations using GitHub Actions error messages.
 - Exits with a nonzero status code if unauthorized changes are found.
