Current version of leafnode 2? <issing configure file?

I'm trying to install leafnode 2 on a new machine.  Is this the right
place to get the current version from?

<https://gitlab.com/leafnode-2/leafnode-2/>

If so, how do I run the './configure --.....' step?  There's no
configure file.

(The version running on the old machine described itself as
'leafnode-2.0.0.alpha20121101a'.)

Thanks.
