+# How to ran NFS jobs
+You need to se use_nfs: True on slave that will ran NFS jobs.
+A working NFS server must be working on the host.
+Furthermore, you must create a /var/lib/lava/dispatcher/tmp directory on the host and export it like:
+/var/lib/lava/dispatcher/tmp 192.168.66.0/24(no_root_squash,rw,no_subtree_check)
+
 ## How to add custom LAVA patchs
 You can add custom or backported LAVA patchs in lava-master/lava-patch
 Doing the same for lava-slave will be done later.
