+=======================
+Mount CephFS on Windows
+=======================
+
+``ceph-dokan`` can be used for mounting CephFS filesystems on Windows.
+It leverages Dokany, a Windows driver that allows implementing filesystems in
+userspace, pretty much like FUSE.
+
+Please check the `installation guide`_ to get started.
+
+Usage
+=====
+
+Mounting filesystems
+--------------------
+
+In order to mount a ceph filesystem, the following command can be used::
+
+ ceph-dokan.exe -c c:\ceph.conf -l x
+
+This will mount the default ceph filesystem using the drive letter ``x``.
+If ``ceph.conf`` is placed at the default location, which is
+``%ProgramData%\ceph\ceph.conf``, then this argument becomes optional.
+
+The ``-l`` argument also allows using an empty folder as a mountpoint
+instead of a drive letter.
+
+The uid and gid used for mounting the filesystem default to 0 and may be
+changed using the following ``ceph.conf`` options::
+
+ [client]
+ # client_permissions = true
+ client_mount_uid = 1000
+ client_mount_gid = 1000
+
+If you have more than one FS on your Ceph cluster, use the option
+``--client_fs`` to mount the non-default FS::
+
+ mkdir -Force C:\mnt\mycephfs2
+ ceph-dokan.exe --mountpoint C:\mnt\mycephfs2 --client_fs mycephfs2
+
+CephFS subdirectories can be mounted using the ``--root-path`` parameter::
+
+ ceph-dokan -l y --root-path /a
+
+If the ``-o --removable`` flags are set, the mounts will show up in the
+``Get-Volume`` results::
+
+ PS C:\> Get-Volume -FriendlyName "Ceph*" | `
+ Select-Object -Property @("DriveLetter", "Filesystem", "FilesystemLabel")
+
+ DriveLetter Filesystem FilesystemLabel
+ ----------- ---------- ---------------
+ Z Ceph Ceph
+ W Ceph Ceph - new_fs
+
+Please use ``ceph-dokan --help`` for a full list of arguments.
+
+Credentials
+-----------
+
+The ``--id`` option passes the name of the CephX user whose keyring we intend to
+use for mounting CephFS. The following commands are equivalent::
+
+ ceph-dokan --id foo -l x
+ ceph-dokan --name client.foo -l x
+
+Unmounting filesystems
+----------------------
+
+The mount can be removed by either issuing ctrl-c or using the unmap command,
+like so::
+
+ ceph-dokan.exe unmap -l x
+
+Note that when unmapping Ceph filesystems, the exact same mountpoint argument
+must be used as when the mapping was created.
+
+Limitations
+-----------
+
+Be aware that Windows ACLs are ignored. Posix ACLs are supported but cannot be
+modified using the current CLI. In the future, we may add some command actions
+to change file ownership or permissions.
+
+Another thing to note is that cephfs doesn't support mandatory file locks, which
+Windows is heavily rely upon. At the moment, we're letting Dokan handle file
+locks, which are only enforced locally.
+
+Unlike ``rbd-wnbd``, ``ceph-dokan`` doesn't currently provide a ``service``
+command. In order for the cephfs mount to survive host reboots, consider using
+``NSSM``.
