 In some cases, especially if you think that something does not work as it should,
-try to update Web UI once more, overriding version checking for the second update.
-This may be required because of some changes we have possibly made to the updating

+
+### Web UI Development.
+
+If you want to help us with developing of the web interface for our
+ firmware, here is what you need to know beforehands. Cameras are very
+ limited in terms of space and performance. The only available option
+ we have now in the firmware which is more or less suitable for dynamic
+ generating of HTML pages is `haserl`, a fancy cousin of `ash` bent for
+ serving as a CGI wrapper. Did I say `ash`? Right, because we don't have
+ `bash`, `tcsh`, `zsh` in our Linux. Ash it is. As in A shell, full name
+ Almquist shell. Tiny, lightweight, and kinda limited. System is limited,
+ too -- in most parts it is `busybox`. So, if you still feel comfortable
+ tonmake your hands dirty with a very 80s style of web development then
+ welcome aboard.
+
+Recent interface is built around [Bootstrap](https://getbootstrap.com/)
+ CSS framework which is a little overkill for the purpouse but allowed us
+ to fasttrack from the original microbe web to what we have now. We would
+ like to slim down the original Bootstrap bundle and create a custom pack
+ with only the features we use. If you posses such a skill, come and work
+ with us.
+
+Also, we're considering the possibility of switching to a client-side
+ web interface builder, leaving only data-tossing to the server. Vue.js
+ or similar. Have something to add here? Spill it out.
+
+Any other ideas? We would like to listen them, too.
+
+### Running a development version of Web UI.
+
+To start improving the web interface, clone its GitHub repo locally and
+ set up an NFS mount on your camera to the root directory of the local copy:
+
+```
+mkdir -p /tmp/dev
+mount -t nfs -o nolock,tcp 192.168.1.123:/full/path/to/web/files /tmp/dev
+```
+_(replace 192.168.1.123 and /full/path/to/web/files with your own IP and path)_
+
+Then start another instance of httpd daemon to serve your version of Web UI
+ on another port of the camera, say port 86:
+
+```
+httpd -p 86 -h "/tmp/dev/var/www" -c /dev/null
+```
+
+Now you can work on Web UI source code in your favorite IDE or a text editor
+ on your workstation, and immediately test the changes with a web browser 
+ pointed to port 86 on the camera. _(E.g. http://192.168.1.10:86/)_
+
+Remember that you substitute only web server contents, but there are also
+ supporting scripts residing outside web directory. These scripts might require
+ updating on camera in case you make changes to them, as well. To update a
+ script on camera, open ssh session to the camera and copy updated version of
+ the script from `/tmp/dev/usr/sbin/` to `/usr/sbin/`.
