+    <title>General Information</title>
+    <p>The <seealso marker="tftp#start/1">start/1</seealso> function starts
+      a daemon process listening for UDP packets on a port. When it
+      receives a request for read or write, it spawns a temporary server
+      process handling the transfer.</p>
+    <p>On the client side,
+      function <seealso marker="tftp#read_file/3">read_file/3</seealso>
+      and <seealso marker="tftp#write_file/3">write_file/3</seealso>
+      spawn a temporary client process establishing
+      contact with a TFTP daemon and perform the file transfer.</p>
+    <p><c>tftp</c> uses a callback module to handle the file
+      transfer. Two such callback modules are provided,
+      <c>tftp_binary</c> and <c>tftp_file</c>. See
+      <seealso marker="tftp#read_file/3">read_file/3</seealso> and
+      <seealso marker="tftp#write_file/3">write_file/3</seealso> for details.
+      You can also implement your own callback modules, see
+      <seealso marker="tftp#tftp_callback">CALLBACK FUNCTIONS</seealso>.
+      A callback module provided by
+      the user is registered using option <c>callback</c>, see

+    <title>Using the TFTP client and server</title>
+    <p>This is a simple example of starting the TFTP server and reading the content

+
+    <p><em>Step 1.</em> Create a sample file to be used for the transfer:</p>
+    <code>
+      $ echo "Erlang/OTP 21" > file.txt
+    </code>
+
+    <p><em>Step 2.</em> Start the TFTP server:</p>
+    <code type="erl" >
+      1> {ok, Pid} = tftp:start([{port, 19999}]).
+      <![CDATA[{ok,<0.65.0>}]]>
+    </code>
+
+    <p><em>Step 3.</em> Start the TFTP client (in another shell):</p>
+    <code type="erl" >
+      1> tftp:read_file("file.txt", binary, [{port, 19999}]).
+      <![CDATA[{ok,<<"Erlang/OTP 21\n">>}]]>

+  <section>
+    <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>
+  </section>
+
+  <section>
+    <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>
+  </section>

-    <p>This is a complete implementation of 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 "netascii" transfer mode.</p>
-    <p>The <seealso marker="#start/1">start/1</seealso> function starts
-      a daemon process listening for UDP packets on a port. When it
-      receives a request for read or write, it spawns a temporary server
-      process handling the transfer.</p>
-    <p>On the client side,
-      function <seealso marker="#read_file/3">read_file/3</seealso>
-      and <seealso marker="#write_file/3">write_file/3</seealso>
-      spawn a temporary client process establishing
-      contact with a TFTP daemon and perform the file transfer.</p>
-    <p><c>tftp</c> uses a callback module to handle the file
-      transfer. Two such callback modules are provided,
-      <c>tftp_binary</c> and <c>tftp_file</c>. See
-      <seealso marker="#read_file/3">read_file/3</seealso> and
-      <seealso marker="#write_file/3">write_file/3</seealso> for details.
-      You can also implement your own callback modules, see 
-      <seealso marker="#tftp_callback">CALLBACK FUNCTIONS</seealso>. 
-      A callback module provided by
-      the user is registered using option <c>callback</c>, see

-    
-    <p>A TFTP server can be configured to start statically when starting
-      the <c>Inets</c> application. Alternatively, it can be started dynamically
-      (when <c>Inets</c> is already started) by calling the <c>Inets</c> application 
-      API <c>inets:start(tftpd, ServiceConfig)</c> or
-      <c>inets:start(tftpd, ServiceConfig, How)</c>,
-      see <seealso marker="inets">inets(3)</seealso> for details.
-      The <c>ServiceConfig</c> for TFTP is described in
-      the <seealso marker="#options">DATA TYPES</seealso>
-      section.</p>
-    
-    <p>The TFTP server can be stopped using <c>inets:stop(tftpd, Pid)</c>,
-      see <seealso marker="inets">inets(3)</seealso> for details.</p>
 
-    <p>The TPFT client is of such a temporary nature that it is not
-      handled as a service in the <c>Inets</c> service framework.</p>
