Develop allows you to edit existing Activities or create new ones. It allows the viewing and editing of multiple files and gives easy access to error logs. It includes templates for a number of sample Hello World Activities.

The main screen is shown below. In this case, a new Activity called testgtk2 has been created from the gtk2 "Hello World" template. The left pane shows the files and directories that comprise the Activity and the right pane shows the contents of its main file, activity.py

==Tutorial - creating your Activity==
Open Develop, start new
Create a new Activity
Select the type Gtk2
Name the Activity testgtk2
Press the Run activity button on the toolbar, your testgtk2 Activity will run, it prints Hello World!. (If you look at your Home screen you have a new Activity called testgtk2.)
Stop testgtk2 and return to Develop. Edit line 70 of activity.py, "Hello World!", change this text but be careful only to change the text within the quotation marks. Press the Run activity button, the Activity now displays the new text.
===Changing the icon===
Shown in the left hand pane is the directory activity with a triangle next to it pointing right. Click on it to see its contents, open activity-helloworld.svg
Line 11 defines the circle of the world in the icon. Change stroke-width to "6.5". You need to restart the laptop to see the changes, the circle is now thicker. [[File:Altered-icon.jpg|50px]]
===Changing the version number===
The Home view, List view shows the version number of all the installed Activities. The version number discriminates between older and newer versions of an Activity. It is used to tell if you are using the latest version. Sometimes the latest version has a bug and you want to go back to an earlier known good version.
Look in your Home view List view and you will see that testgtk2 is version 1. To alter the version number, edit activity.info line 6 which shows the activity_version=1 , change it to 2.
You may need to restart the laptop to see the changes.
===Installing your Activity on another computer===
Press the Create bundle button on the home toolbar[[File:Save-bundle.jpg]], this creates a .xo bundle in the Journal. Copy this to another laptop to install your Activity.
