  follow these instructions.
</p>


<h2>

</p>

</p>

<div class="indent">
  <div class="frame">
<pre class="source-body">C:\Program Files\Borland\Delphi4\Help\MyHelp.hlp</pre>
  </div>
</div>

<p>
  to the registry insert a value named MyHelp.hlp, with the above path as the
  value.
</p>

<h2>
  2: Enable Delphi to display the component's help keywords in the index
</h2>

<p>
  Open
</p>

<div class="indent">
  <div class="frame">
<pre class="source-body">C:\Program Files\Borland\Delphi4\Help\delphi4.cnt</pre>
  </div>
</div>

<p>
  and add the following entry to the end of the file's index section:
</p>

<div class="indent">
  <div class="frame">
<pre class="source-body">:Index My Help Title=MyHelp.hlp</pre>
  </div>
</div>

<h2>
  3: Add link support to Delphi's Help system

<p>
  Open
</p>

<div class="indent">

<pre class="source-body">C:\Program Files\Borland\Delphi4\Help\delphi4.cfg</pre>
  </div>
</div>

<p>
  Add the following line to the end of the file:
</p>

<div class="indent">

  </div>
</div>

<p>
  Then add
</p>

<div class="indent">

  </div>
</div>

<p>
  to your contents file (<code>MyHelp.cnt</code>).
