+    <title>Purpose</title>
+    <p>The Trivial File Transfer Protocol or TFTP is a very simple protocol
+    used to transfer files.</p>
+    <p>It has been implemented on top of the User Datagram protocol (UDP) so
+    it may be used to move files between machines on different networks
+    implementing UDP. It is designed to be small and easy to implement.
+    Therefore, it lacks most of the features of a regular FTP.  The only
+    thing it can do is read and write files (or mail) from/to a remote server.
+    It cannot list directories, and currently has no provisions for user
+    authentication.</p>
+    <p>The <c>tftp</c> application implements the following IETF standards:</p>
+    <list type="bulleted">
+      <item>RFC 1350, The TFTP Protocol (revision 2)</item>
+      <item>RFC 2347, TFTP Option Extension</item>
+      <item>RFC 2348, TFTP Blocksize Option</item>
+      <item>RFC 2349, TFTP Timeout Interval and Transfer Size Options</item>
+    </list>
+    <p>The only feature that not is implemented is the <c>netascii</c> transfer mode.</p>

+    <title>Prerequisites</title>
+    <p>It is assumed that the reader is familiar with the Erlang
+      programming language, concepts of OTP, and has a basic
+      understanding of the TFTP protocol.</p>
