+    <li>
+      Linux has several firewall APIs - iptables, ip6tables, arptables
+      and ebtables
+    </li>
+    <li>
+      All require a specific kernel module for each type of match
+      and each possible action
+    </li>
+    <li>
+      Userland could only use the four protocol-specific APIs,
+      although the internal netfilter API is more flexible
+    </li>
+    <li>
+      nftables exposes more of this flexibility, allowing userland
+      to provide firewall code for a specialised VM (similar to BPF)
+    </li>
+    <li>
+      nftables userland tool uses this API and is already packaged
+    </li>
+    <li>
+      Eventually, the old APIs will be removed and the old userland
+      tools must be ported to use nftables
+    </li>
