+<h3>Adding a custom MIDNAM-file</h3>
+<p>
+ MIDNAM-files are XML-Files. You can edit them using your favorite text-editor. When
+ doing so, please ensure to change the "Model" of the device, as Ardour will only load
+ each model once (i.e. it will skip files, if there are clashes).
+</p>
+<p>
+ After you have done modifications to a file, it is a good idea to validate it. This can
+ be done using the tool <i>xmllint</i> as shown below:
+</p>
+<pre><code class="bash">
+$ xmllint --valid --noout myfile.midnam
+$ wget http://www.midi.org/dtds/MIDINameDocument10.dtd
+$ xmllint --dtdvalid MIDINameDocument10.dtd myfile.midnam
+</code></pre>
+<p>
+ Once you are satisfied with your file, you have to put it at a location where Ardour
+ picks it up. The best place would be the (hidden) directory
+ <a href="@@files-and-directories-ardour-knows-about">Ardour configuration directory</a>
+ subdirectory patchfiles.
+ in your home-folder. Should the sub-directory <i>patchfiles</i> not exist yet, just
+ create it. The path and file-names are case-sensitive. The file should end with
+ "<i>.midnam</i>".
+</p>
+<p>
+ After restarting Ardour, hit the small Log-button in the upper right corner of the
+ main window. It should say something like
+ (this is Linux, Macos or Windows will be different):
+</p>
+<pre>[INFO]: Loading 3 MIDI patches from /home/username/.config/ardour5/patchfiles</pre>
+<p>
+ The added device should now show up in the dropdown mentioned in the previous paragraph.
+</p>
+<p>
+ Should the MIDNAM-file be useful for the general public, it would be nice to share it:
+ Fork the Ardour-project on <a href="https://github.com/Ardour/ardour">gitHub</a> by
+ hitting the "Fork"-Button. Go to the <a>patchfiles</a>-directory (and read the README).
+</p>
+<p>
+ You can upload the file using the Web-Interface. Be sure to select
+ "<i>Create a new branch for this commit and start a pull request</i>".
