+
+This project is a fork of `kyuupichan/electrumx <https://github.com/kyuupichan/electrumx>`_.
+The original author dropped support for Bitcoin, which we intend to keep.
+
+ElectrumX allows users to run their own Electrum server. It connects to your
+full node and indexes the blockchain, allowing efficient querying of history of
+arbitrary addresses. The server can be exposed publicly, and joined to the public network
+of servers via peer discovery. As of May 2020, a significant chunk of the public
+Electrum server network runs ElectrumX.
+
+The current version is |release|.
+
