 DESCRIPTION
 -----------
 *btrfs restore* is used to try to salvage files from a damaged filesystem and
-restore them into <path> or just list the tree roots.
+restore them into <path> or just list the subvolume tree roots. The filesystem
+image is not modified.
 
-Since current `btrfs-check`(8) or `btrfs-rescue`(8) only has very limited usage,
-*btrfs restore* is normally a better choice.
+If the filesystem is damaged and cannot be repaired by the other tools
+(`btrfs-check`(8) or `btrfs-rescue`(8)), *btrfs restore* could be used to
+retrieve file data, as far as the metadata are readable. The checks done by
+restore are less strict and the process is usually able to get far enough to
+retrieve data from the whole filesystem. This comes at a cost that some data
+might be incomplete or from older versions if they're available.
+
+There are several options to attempt restoration of various file metadata type.
+You can try a dry run first to see how well the process goes and use further
+options to extend the set of restored metadata.
+
+For images with damaged tree structures, there are several options to point the
+process to some spare copy.
 
 NOTE: It is recommended to read the following btrfs wiki page if your data is
 not salvaged with default option: +

 --path-regex <regex>::
-restore only filenames matching regex, you have to use following syntax (possibly quoted):
+restore only filenames matching a regular expression (`regex`(7)) with a
+mandatory format
 +
 +^/(|home(|/username(|/Desktop(|/.*))))$+
++
+The format is not very comfortable and restores all files in the directories
+in the whole path, so this is not useful for restoring single file in a deep
+hierarchy.
