                I only have one error in the topology, I created
                the script as described in the guide
                https://openwisp.io/docs/user/network-topology.html

                This is my output:

                Hi everyone!

                I just wanted to let you know that I just finished
                merging the work to integrate ZeroTier into the
                development version of OpenWISP, find more
                information on how to set this up here:
                https://openwisp.io/docs/user/zerotier.html

                This feature will be shipped in the next release,
                if you want to try it before then you can do so by
                deploying the development version of OpenWISP, to
                do that you need to use the latest master of the
                ansible-openwisp2
                <https://github.com/openwisp/ansible-openwisp2> role.

                Many thanks to Aryaman for working on this during
                the last Google Summer of Code under the guidance
                of Gagan Deep, Ajay Tripathi and myself.

                I am proud of the result we have achieved, as the
                first iteration I think it's really good.

                I am eager to see this work deployed all around
                the world!

                Best regards
