+[![Latest PyPI package](https://badge.fury.io/py/e_x.svg)](https://pypi.org/project/e-x/)
+[![Build Status](https://github.com/spesmilo/electrumx/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/spesmilo/electrumx/actions/workflows/ci.yml)

+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 the 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.
