+SquashFS filesystem
+===================
+
+SquashFS is a highly compressed read-only filesystem for Linux.
+It uses zlib, lzo or xz compression to compress both files, inodes
+and directories. A SquashFS filesystem can be mounted using the
+:ref:`command_mount` command::
+
+ barebox:/ mkdir /mnt
+ barebox:/ mount -t squashfs /dev/spiflash.FileSystem /mnt
+ barebox:/ ls /mnt
+ zImage barebox.bin
+ barebox:/ umount /mnt
