# Eligible Receiver
# ================
Eligible Receiver is a tool for finding eligible receivers for a given set of conditions. It is designed to be used in conjunction with the [Eligible Receiver API](https://eligiblereceiver.cloud/).

## Installation
Eligible Receiver is available as a release on [GitHub](https://github.com/TrainGRC/eligiblereceiver/releases). Download the latest release and extract the contents to a directory of your choice. You can then run the application by executing the `eligiblereceiver` binary.
