 * Adding extra apps
 Suppose you have some internet application which you want to add to the system. To do this you need to create an app script which tells the system how to install/remove and also backup/restore. The script should be designed to work with the current stable version of Debian.
 
-On an installed system the app scripts go into the directory:
+There's a command which you can use to generate scripts for new apps. Some examples are as follows:
+
+To create a script for a generic PHP plus MySql/MariaDB web app:
 
 #+begin_src bash
-/usr/share/freedombone/apps
+freedombone-template --app [name] -e [email] -r [repo url] -c [commit] --php yes -d mariadb > src/freedombone-app-myappname
 #+end_src
 
-and within the project repo they appear within the /src/ directory. Your new app script should have the name:
+For a Nodejs app with MySql/MariaDB database:
 
 #+begin_src bash
-freedombone-app-[myappname]
+freedombone-template --app [name] -e [email] -r [repo url] -c [commit] --node yes -d mariadb --dir /etc/myappname --daemon yes > src/freedombone-app-myappname
 #+end_src
 
-The /myappname/ value should not contain any spaces and will appear in the list of available apps.
-
-An example template for an app script is shown below. Copy this and add whatever variables and configuration you need. Search and replace /myappname/ with your own.
+For a Python app with Postgresql database:

+make install

-Select *Add/Remove Apps* and if all is well then you should see your app listed as installable. Test that installing and removing it works as expected.
+Then run the administrator control panel and you should see the new app within *Add/Remove apps*.
 
-Submit your working app to *https://github.com/bashrc/freedombone/issues*
+Submit your working app to *https://github.com/bashrc/freedombone/issues* or create a pull request.
 
 * Customising mesh images
 If you want to make your own specially branded version of the mesh images, such as for a particular event, then to change the default desktop backgrounds edit the images within *img/backgrounds* and to change the available avatars and desktop icons edit the images within *img/avatars*. Re-create disk images using the instructions shown previously.

 Freedombone consists of a set of bash scripts. There are a lot of them, but they're not very complicated. If you're familiar with the GNU/Linux commandline and can hack a bash script then you can probably add a new app or fix a bug in the system. There are no trendy development frameworks to learn or to get in your way. You might also want to consult the <a href="./codeofconduct.html">Code of Conduct</a>.
