+### Combining short Bool options
+
+Traditional use of boolean options using their shortnames look like this:
+```
+# cmd foobar -s -o
+```
+
+Suppose you want users to be able to combine your bool options with their shortname. This
+can be done using the **UseShortOptionHandling** bool in your commands. Suppose your program
+has a two bool flags such as *serve* and *option* with the short options of *-o* and
+*-s* respectively. With **UseShortOptionHandling** set to *true*, a user can use a syntax
+like:
+```
+# cmd foobar -so
+```
+
+If you enable the **UseShortOptionHandling*, then you must not use any flags that have a single
+leading *-* or this will result in failures. For example, **-option** can no longer be used. Flags
+with two leading dashes (such as **--options**) are still valid.
