+Role Name
+=========
+
+Create a filesystem on the target device (thinly wraps `community.general.filesystem` module).
+
+Requirements
+------------
+
+Uses specific tools related to the fstype for creating or resizing a filesystem (`e2fsprogs`, `xfsprogs`, etc.).
+
+Uses generic tools mostly related to the OS, like `blkid`.
+
+Role Variables
+--------------
+
+- `mkfs_device`: (string) device that the filesystem should be created on
+- `mkfs_type`: (string) type of the filesystem to be created
+- `mkfs_opts`: (string) a list of options to be passed to `mkfs` (*not* a YAML array)
+- `mkfs_state`: (string) `absent` or `present`
+- `mkfs_force`: (boolean) overwrite an existing fs if there is one (default: `false`)
+
+Dependencies
+------------
+
+None
+
+Example Playbook
