-The first variable, `weave_seed`, contains the initial nodes of the weave network
-
-The second variable, `weave_peers`, saves the IPs of all nodes joined to the weave network
-
-These two variables are used to connect a new node to the weave network. The new node needs to know the firsts nodes (seed) and the list of IPs of all nodes.
-
-To reset these variables and reset the weave network set them to `uninitialized`
+See [weave ipam documentation](https://www.weave.works/docs/net/latest/tasks/ipam/ipam/) and use `weave_extra_args` to enable.
