+<h1>STM32 firmware for Cryptech Alpha board</h1>
+
+<p>The Alpha board is our first full prototype for an open-source hardware
+security module (HSM). It is a custom board with an STM32 Cortex-M4
+microcontroller and an Artix-7 FPGA, flash-based keystore, separate memory
+for the Key Encryption Key, etc. See the wiki for design documents.</p>
+
+<h1>Copyrights</h1>
+
+<p>The license for all work done on this in the CrypTech project is a
+3-clause BSD license.</p>
+
+<p>The "Noise generator" and "Amplifier" parts of the circuit diagram are
+copied from Benedikt Stockebrand's ARRGH project. </p>
+
+<p>Both copyright statements are included in LICENSE.txt.</p>
+
+<h1>Board Revisions</h1>
+
+<ol>
+<li><p><code>rev01</code> was the "dev-bridge" board, a daughterboard for the Novena,
+which talked to the Novena's FPGA through the high-speed expansion
+connector.</p></li>
+<li><p><code>rev02</code> is the Alpha board, our first full prototype for an open-source
+hardware security module (HSM). It is a custom board with an STM32
+Cortex-M4 microcontroller and an Artix-7 FPGA, flash-based keystore,
+separate memory for the Key Encryption Key, etc.</p>
+
+<p>The board's form factor (4 x 4 in, 101.6 x 101.6 mm) was based on the
+Intel NUC mini-PC, but there were some issues sourcing enough cases, so
+only a few of these boards were made.</p></li>
+<li><p><code>rev03</code> is functionally the same as <code>rev02</code>, but in a Eurocard form
+factor (100 x 120 mm, aka "3Ux120").</p></li>
+</ol>
