+var selfUpdateHelp string = `
+This command downloads the latest release of rclone and replaces
+the currently running binary. The download is verified with a hashsum
+and cryptographically signed signature.
+
+If used without flags (or with implied |--stable| flag), this command
+will install the latest stable release. However, some issues may be fixed
+(or features added) only in the latest beta release. In such cases you should
+run the command with the |--beta| flag, i.e. |rclone selfupdate --beta|.
+You can check in advance what version would be installed by adding the
+|--check| flag, then repeat the command without it when you are satisfied.
+
+Sometimes the rclone team may recommend you a concrete beta or stable
+rclone release to troubleshoot your issue or add a bleeding edge feature.
+The |--version VER| flag, if given, will update to the concrete version
+instead of the latest one. If you omit micro version from |VER| (for
+example |1.53|), the latest matching micro version will be used.
+
+Upon successful update rclone will print a message that contains a previous
+version number. You will need it if you later decide to revert your update
+for some reason. Then you'll have to note the previous version and run the
+following command: |rclone selfupdate [--beta] OLDVER|.
+If the old version contains only dots and digits (for example |v1.54.0|)
+then it's a stable release so you won't need the |--beta| flag. Beta releases
+have an additional information similar to |v1.54.0-beta.5111.06f1c0c61|.
+(if you are a developer and use a locally built rclone, the version number
+will end with |-DEV|, you will have to rebuild it as it obvisously can't
+be distributed).
+
+If you previously installed rclone via a package manager, the package may
+include local documentation or configure services. You may wish to update
+with the flag |--package deb| or |--package rpm| (whichever is correct for
+your OS) to update these too. This command with the default |--package zip|
+will update only the rclone executable so the local manual may become
+inaccurate after it.
+
+The |rclone mount| command (https://rclone.org/commands/rclone_mount/) may
+or may not support extended FUSE options depending on the build and OS.
+|selfupdate| will refuse to update if the capability would be discarded.
+
+Note: Windows forbids deletion of a currently running executable so this
+command will rename the old executable to 'rclone.old.exe' upon success.
+
+Please note that this command was not available before rclone version 1.55.
+If it fails for you with the message |unknown command "selfupdate"| then
+you will need to update manually following the install instructions located
+at https://rclone.org/install/
+`

 To copy files and directories from `example.com` in the relative

+### Connection strings {#connection-strings}
+
+The above examples can also be written using a connection string
+syntax, so instead of providing the arguments as command line
+parameters `--http-url https://pub.rclone.org` they are provided as
+part of the remote specification as a kind of connection string.
+
+    rclone lsd ":http,url='https://pub.rclone.org':"
+    rclone lsf ":http,url='https://example.com':path/to/dir"
+    rclone copy ":http,url='https://example.com':path/to/dir" /tmp/dir
+    rclone copy :sftp,host=example.com:path/to/dir /tmp/dir
+
+These can apply to modify existing remotes as well as create new
+remotes with the on the fly syntax. This example is equivalent to
+adding the `--drive-shared-with-me` parameter to the remote `gdrive:`.
+
+    rclone lsf "gdrive,shared_with_me:path/to/dir"
+
+The major advantage to using the connection string style syntax is
+that it only applies the the remote, not to all the remotes of that
+type of the command line. A common confusion is this attempt to copy a
+file shared on google drive to the normal drive which **does not
+work** because the `--drive-shared-with-me` flag applies to both the
+source and the destination.
+
+    rclone copy --drive-shared-with-me gdrive:shared-file.txt gdrive:
+
+However using the connection string syntax, this does work.
+
+    rclone copy "gdrive,shared_with_me:shared-file.txt" gdrive:
+
+The connection strings have the following syntax
+
+    remote,parameter=value,parameter2=value2:path/to/dir
+    :backend,parameter=value,parameter2=value2:path/to/dir
+
+If the `parameter` has a `:` or `,` then it must be placed in quotes `"` or
+`'`, so
+
+    remote,parameter="colon:value",parameter2="comma,value":path/to/dir
+    :backend,parameter='colon:value',parameter2='comma,value':path/to/dir
+
+If a quoted value needs to include that quote, then it should be
+doubled, so
+
+    remote,parameter="with""quote",parameter2='with''quote':path/to/dir
+
+This will make `parameter` be `with"quote` and `parameter2` be
+`with'quote`.
+
+If you leave off the `=parameter` then rclone will substitute `=true`
+which works very well with flags. For example to use s3 configured in
+the environment you could use:
+
+    rclone lsd :s3,env_auth:
+
+Which is equivalent to
+
+    rclone lsd :s3,env_auth=true:
+
+Note that on the command line you might need to surround these
+connection strings with `"` or `'` to stop the shell interpreting any
+special characters within them.
+
+If you are a shell master then you'll know which strings are OK and
+which aren't, but if you aren't sure then enclose them in `"` and use
+`'` as the inside quote. This syntax works on all OSes.
+
+    rclone copy ":http,url='https://example.com':path/to/dir" /tmp/dir
+
+On Linux/macOS some characters are still interpreted inside `"`
+strings in the shell (notably `\` and `$` and `"`) so if your strings
+contain those you can swap the roles of `"` and `'` thus. (This syntax
+does not work on Windows.)
+
+    rclone copy ':http,url="https://example.com":path/to/dir' /tmp/dir
+
+#### Connection strings, config and logging
+
+If you supply extra configuration to a backend by command line flag,
+environment variable or connection string then rclone will add a
+suffix based on the hash of the config to the name of the remote, eg
+
+    rclone -vv lsf --s3-chunk-size 20M s3:
+
+Has the log message
+
+    DEBUG : s3: detected overridden config - adding "{Srj1p}" suffix to name
+
+This is so rclone can tell the modified remote apart from the
+unmodified remote when caching the backends.
+
+This should only be noticeable in the logs.
+
+This means that on the fly backends such as
+
+    rclone -vv lsf :s3,env_auth:
+
+Will get their own names
+
+    DEBUG : :s3: detected overridden config - adding "{YTu53}" suffix to name

+Sections of text, led by a `[section]` header and followed by

+represented by its own section, where the section name defines the
+name of the remote. Options are specified as the `key=value` entries,
+where the key is the option name without the `--backend-` prefix,
+in lowercase and with `_` instead of `-`. E.g. option `--mega-hard-delete`
+corresponds to key `hard_delete`. Only backend options can be specified.
+A special, and required, key `type` identifies the [storage system](/overview/),

+of passwords, and this requires additional steps. It is easier, and safer,
+to use the interactive command `rclone config` instead of manually
+editing the configuration file.
+
+The configuration file will typically contain login information, and
+should therefore have restricted permissions so that only the current user
+can read it. Rclone tries to ensure this when it writes the file.
+You may also choose to [encrypt](#configuration-encryption) the file.

+When token-based authentication are used, the configuration file

-which allows paths up to 32,767 characters.
+On Windows there are many ways of specifying a path to a file system resource.
+Both absolute paths like `C:\path\to\wherever`, and relative paths like
+`..\wherever` can be used, and path separator can be either
+`\` (as in `C:\path\to\wherever`) or `/` (as in `C:/path/to/wherever`).
+Length of these paths are limited to 259 characters for files and 247
+characters for directories, but there is an alternative extended-length
+path format increasing the limit to (approximately) 32,767 characters.
+This format requires absolute paths and the use of prefix `\\?\`,
+e.g. `\\?\D:\some\very\long\path`. For convenience rclone will automatically
+convert regular paths into the corresponding extended-length paths,
+so in most cases you do not have to worry about this (read more [below](#long-paths)).
 
-This is why you will see that your paths, for instance `c:\files` is
-converted to the UNC path `\\?\c:\files` in the output,
-and `\\server\share` is converted to `\\?\UNC\server\share`.
+Note that Windows supports using the same prefix `\\?\` to
+specify path to volumes identified by their GUID, e.g.
+`\\?\Volume{b75e2c83-0000-0000-0000-602f00000000}\some\path`.
