+** On the Server **
+This documents takes you through setting nfs shares on a fedora family OS. The
+core packages that need to be present are =autofs, nfs-utils=
+```
+sudo dnf install autofs nfs-utils
+```
+Create the directories to share. In this case two folders under the share
+directory
+```
+mkdir -p /shares/share{1,2}
+```
+To tell nfs-server, what folders to share we edit the ==/etc/exports== with the
+following lines:
+```
+/shares     *(rw,no_root_squash)
+```
+For more examples on how to edit ==/etc/exports== consult the man page at `man
+exports` and navigate to the bottom of the page.
+```
+systemctl start nfs-server
+systemctl enable nfs-server
+```
+Allow external programs access by changing the firewall(nftables). Rpcbind,
+mountd, nfs are related services that need access.
+```
+for i in rpc-bind mountd nfs; do firewall-cmd --permanent --add-service $i; done;
+firewall-cmd --reload
+firewall-cmd --list-services        # confirm changes 
+```
+
+**On the Client**
+Make sure the required packages are installed as seen above. Use ==showmount==
+to verify the shared folders.
+```
+showmount -e ip_address_server/hostname   # verify /etc/hosts in case of issues
+```
+Tell autofs the shared folders to mount and the location of their config file.
+```
+# in /etc/auto.master
+/shares     /etc/auto.shares        # replaces shares with any file/name
+```
+Tell autofs how to mount /shares in /etc/auto.shares
+```
+*   -rw     hostname:/shares/&
+```
+Mounts all folders exported thanks to the wildcard character. The ampersand
+matches any subdirectory in the ==/shares==
+
+Start the autofs service
+```
+systemctl start autofs
+systemctl enable autofs
+```
+Confirm folder gets mounted when you navigate to it `cd /shares/`
