 # Setting up the files
 
 * Add the two files [41-enable-he-ipv6.sh](mnt/data/on_boot.d/41-enable-he-ipv6.sh) and [99-add-cronjobs.sh](mnt/data/on_boot.d/99-add-cronjobs.sh) to `/mnt/data/on_boot.d/` 
-  * (both of these files should be executable with `chmod +x {filename}`
-* Add a folder, `/mnt/data/cronjobs/` and put the file [update_ipv6_chains](mnt/data/cronjobs/update_ipv6_chains) in that folder.
-* Add a folder, `/mnt/data/ipv6/` and drop both files [enable-he-ipv6.sh](/mnt/data/ipv6/enable-he-ipv6.sh) and [configure-he-ipv6-chains.sh](/mnt/data/ipv6/configure-he-ipv6-chains.sh) in that folder.
-  * (both of these files also should be made executable with `chmod +x {filename}`
+* Make both of those files executable: 
+  * `chmod +x /mnt/data/on_boot.d/41-enable-he-ipv6.sh`
+  * `chmod +x /mnt/data/on_boot.d/99-add-cronjobs.sh`
+* Create a folder, `mkdir /mnt/data/cronjobs/` and put the file [update_ipv6_chains](mnt/data/cronjobs/update_ipv6_chains) in that folder.
+* Create a folder, `mkdir /mnt/data/ipv6/` and drop both files [enable-he-ipv6.sh](/mnt/data/ipv6/enable-he-ipv6.sh) and [configure-he-ipv6-chains.sh](/mnt/data/ipv6/configure-he-ipv6-chains.sh) in that folder.
+* Make both of those files executable:  
+  * `chmod +x /mnt/data/ipv6/enable-he-ipv6.sh` 
+  * `chmod +x /mnt/data/ipv6/configure-he-ipv6-chains.sh`
 * Edit the file [/mnt/data/ipv6/enable-he-ipv6.sh](/mnt/data/ipv6/enable-he-ipv6.sh) and change the two properties `REMOTE_ENDPOINT` and `LOCAL_IPV6` to match the values from `Server IPv4 Address` and `Client IPv6 Address` respectively
   * those values can be found on tunnelbroker.net in your **tunnel details** page
