     6) Browse to the folder where you extracted bookloupe
 
     7) Double-click bookloupe.exe 
+
+    Now, whenever you do "Gutcheck" in Guiguts, it will run bookloupe
+    instead. Since the output will look very like gutcheck output, you
+    may want to check that it is actually bookloupe that is running. To do
+    this, look at the black command line message window, which will say:
+
+    "bookloupe: Check and report on an e-text".
+
+    To return to using gutcheck for any reason, repeat steps 4 and 5
+    above, and then,

+    6b) Browse back to the gutcheck folder, which is in a "tools"
+    folder inside the main Guiguts folder. It will be something like
+    "C:\DP\guiguts-win\tools\gutcheck", depending on where you installed
+    Guiguts originally.
+
+    7b) Double-click gutcheck.exe
+
+    Now doing "Gutcheck" in Guiguts will run gutcheck itself, and the
+    message in the black window should read:
+
+    "gutcheck: Check and report on an e-text".
