+### Explanation
+
+In UNIX-like systems, non-root users are unable to bind to ports lower than 1024.
+
+This is a nuisance while proxying adresses on port 80. Tipically, you end up `sudo`ing all apps that must bind to such ports.
+
+However, since kernel 2.6.24, you can use the `setcap` command to set specific capabilities to a program.
+
+To enable **all node programs to bind on any port lower than 1024**, issue the following command:
+
+    sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node
+
+*Voilà*! You can now bind to port 80 without `sudo`ing. 
+
+If your `node` binary isn't on this path, find it with `whereis node` and substitute `/usr/local/bin/node` for wherever it is.
+
+### Important Caveat
+
+`setcap` functions *per-program*. Therefore, if you update your node version you will probably need to run this command again.
