+# Introduction
+
+The Quantum Entropy Appliance (QEA) is a server that comes equipped with Qrypt’s quantum random number generator cards. These cards continuously measure quantum phenomena to generate streams of truly random bytes.
+
+The QEA can be installed on-prem, or in a data center, and it does not require any external network access. It exposes a REST API that can be called by clients in the same network to request arbitrary amounts of true random bytes.
+
+---
+# How do we ensure true randomness?
+
+The entropy generated by the QEA is continuously tested using the [NIST SP800-22](https://nvlpubs.nist.gov/nistpubs/legacy/sp/nistspecialpublication800-22r1a.pdf) entropy source validation test suite. If any of the tests fail, then that entropy source is cut off until its output passes tests again.
+
+The appliance also includes an extensive set of hardware health monitors that shut down the entropy source at the card level in the event of any hardware failure or anomaly.
+
+---
+# Performance
+
+**Max API throughput:** ~2,500,000 256-bit keys per second
+
+**Max Entropy card output:** ~1,500 Mb/s
+
+---
+# Installation
+
+The QEA comes with Ubuntu Server v22.04 installed. Users will receive login credentials which they can use to perform any necessary admin tasks.
+
+The QEA can be installed on-prem or in a datacenter rack. Once the appliance is connected to the network interface, the user must log in and configure its network interface (see the [Ubuntu docs](https://ubuntu.com/server/docs/configuring-networks) for a detailed guide on how to set up networking on Ubuntu Server).
+
+---
+# Interacting with the appliance
+
+The QEA listens for incoming requests on port 80.
+
+The root path (“/”) returns a UI that displays various metrics, and health reports. This UI can also be used to download application log files for troubleshooting purposes.
+
+Client applications can request a configurable amount of entropy from the entropy API, which is served from the “/api/v1/” route. The complete spec for the API can be found below.
