 ## System Requirements

 In order to run Wings you will need a system capable of running Docker containers. Most VPS and almost all
 dedicated servers should be capable of running Docker, but there are edge cases.

+### Node Allocations
+
+Allocation is a combination of IP and Port that can be assigned to a server. Each created server must have at least one allocation. The allocation would be the IP address of your network interface, in some cases such as when behind NAT it would be the internal IP. Go to Nodes > Your Node > Allocation
+
+![](../../.vuepress/public/node_allocations.png)
+
+Type `hostname -I | awk '{print $1}'` to find the IP to be used for the allocation. Alternatively, you can type `ip addr | grep "inet "` to find all your available interfaces and IP addresses. Do not use 127.0.0.1 for allocations.
