+ Assuming the previous step was calibration, the image plot will show the located rings or the picked points. These are no longer needed. The Image Controls/Clear Calibration menu entry removes these intermediate results, ''but does not clear the calibration results''. Use of this menu item is not required, but does speed future display of results. 
 
- The GSAS-II program has now been started and an empty project file is created. The project file contains all data and results related to the project you are working on. (Exception: image files are not stored in the project; to save space only the file name is saved.) 
-You should see two windows, both empty. One, in the upper left, is labeled GSASII Plots, the other, in the upper right, is labeled GSAS-II data tree. On Linux and Windows a menu bar appears on the latter data tree window; on a Mac the menu is in the system menu bar location (usually at the screen top). 
+=== Step 2: Integration Settings ===
+
+In the simplest case, all that is needed is to click on the "Do full integration?" checkbox and likely adjust the inner and outer 2-theta values with the two "Inner/Outer 2-theta" controls. For the La_hex_+45deg-00015.tif image loaded before, good values are 0.5 and 7 degrees. 
+
+It is helpful to see the two-theta limits on the plot visually, while adjusting the two-theta range. This is done by clicking on the "Show integration limits?" checkbox. Note that inner limit is shown as a green ellipse and the outer is shown as a red ellipse. Note that changes are displayed only after pressing return, when numbers are placed in the boxes.
