+<H1>Advanced: Generating profile programmatically</H1>
+
+<P><B>WARNING: Consider this part as "unofficial". There is no guarantee that it will work. It may stop working at any time!!!</B></P>
+
+<P>It is possible to generate channels for profile programmatically. It may prove useful e.g. when generating profile with
+lots of similar channels. For start, manually (using QLC+ wizard) create some channels, and then open the profile in a text editor,
+and add the rest of the channels.</P>
+
+<P>Sample code in ruby: Install <a href="https://rubygems.org/gems/digest-crc">digest-crc</a> gem by running:
+
+<pre>
+gem install digest-crc
+</pre>
+
+Script:
+
+<pre>
+require 'digest/crc16_qt'
+dig = Digest::CRC16QT.new
+dig &lt;&lt; ARGV[0]
+crc = dig.checksum
+puts %[ &lt;Channel Number="#{crc}"&gt;]
+puts %[  &lt;Name>#{ARGV[0]}&lt;/Name&gt;]
+puts %[  &lt;Type>Button&lt;/Type&gt;]
+puts " &lt;/Channel&gt;"
+</pre>
+
+Use: 
+<pre>ruby ./crc.rb /myoscmessage</pre>
