+            If a gang member is not earning much money or respect, the task that you
+            have assigned to that member might be too difficult. Consider training that
+            member's stats or choosing an easier task. The tasks closer to the
+            top of the dropdown list are generally easier. Alternatively, the gang member's
+            low production might be due to the fact that your wanted level is too high.
+            Consider assigning a few members to the '{props.gang.isHackingGang?"Ethical Hacking":"Vigilante Justice"}'
+            task to lower your wanted level.

+            Installing Augmentations does NOT reset your progress with your Gang.
+            Furthermore, after installing Augmentations, you will
+            automatically be a member of whatever Faction you created your gang with.
+            <br />
+            <br />
+            You can also manage your gang programmatically through Netscript using the Gang API
