+### VMs with less than 512mb memory
+Having less than 512mb of system-memory available for dokku and its containers, for example Digital Ocean's smallest machines, might result in unexpected errors, such as **! [remote rejected] master -> master (pre-receive hook declined)** during installation of NPM dependencies (https://github.com/npm/npm/issues/3867).
+
+To work around this issue, it might suffice to augment the linux swap file size to a maximum of twice the physical memory size.
+
+To resize the swap file of a 512MB machine to 1GB, follow these steps while in SSH within your machine:
+```
+root@my.droplet:/# cd /var
+root@my.droplet:/# touch swap.img
+root@my.droplet:/# chmod 600 swap.img
+
+root@my.droplet:/# dd if=/dev/zero of=/var/swap.img bs=1024k count=1000
+root@my.droplet:/# mkswap /var/swap.img
+root@my.droplet:/# swapon /var/swap.img
+root@my.droplet:/# free
+
+root@my.droplet:/# echo "/var/swap.img    none    swap    sw    0    0" >> /etc/fstab
+```
