+There exists a project named
+[nmcontrol](https://github.com/namecoin/nmcontrol) to create an
+all-in-one tool that can, among other things, act as a DNS server
+for the `.bit` zone. There is also a tool,
+[NamecoinToBind](https://github.com/namecoin/NamecoinToBind),
+for offline conversion of namecoin data into BIND zone file.
+
+Unlike those, this project is a single-purpose tool acting as a (real
+time) bridge between [Namecoin](http://namecoin.info/) and DNS.
+It is implemented as a `pipe backend` to
+[PowerDNS](https://www.powerdns.com/), which provides stable DNS
+frontend, and has simple backend interface.
+
+## Building
+
+The program is built as a single executable to be run by PowerDns's
+pipe backend. It is written in [Haskell](http://www.haskell.org/).
+There is no `cabal` configuration at the moment, so to build it,
+simply run
