+### Tag Grouping
+New in v1.6.0 is Tag Grouping!  This allows you to assign a group to previous tags defined.
+```bash
+# Group Example #1
+
+# Define your URLs as per normal
+user1=mailto://credentials
+user2=mailto://credentials
+
+# Then define a group
+friends = user1, user2
+```
+With respect to `Group Example #1` above, you could now send a notification to the tag `friends` and that would in turn trigger a notification to all of the URLs that were included indirectly to that tag.  In this case, `user1` and `user2` would be notified.
+
+Another great thing about groups is you can assign groups to groups to recursively include everything they're apart of:
+```bash
+# Group Example #2
+
+# Define your URLs as per normal
+user1=mailto://credentials
+user2=mailto://credentials
+user3=mailto://credentials
+user4=mailto://credentials
+boss=mailto://credentials
+
+# Then define a group
+finance = user1, user2
+devteam = user3, user4
+
+# Here we create another group and assign it groups
+# We also can mix and max tags in line with group assignments too
+# like so:
+company = finance, devteam, boss
+
+```
+With respect to `Group Example #2` above, you could now send a notification to the tag `company` and that would in turn trigger a notification to everyone because they're all associated with the group tag.
+
+You can also assign tags to multiple groups:
+```bash
+# Group Example #3
+
+# Define your URLs as per normal
+user1=mailto://credentials
+user2=mailto://credentials
+user3=mailto://credentials
+user4=mailto://credentials
+
+# Multiple Group Assignments; reuse of a tag causes existing assignment
+# to stack on the previous value.
+TeamA, Friends = user1, user3
+TeamB, Friends = user2, user4
+
+```
+With respect to `Group Example #3` above, we have 3 group tags created (TeamA, TeamB, and Friends).  TeamA includes user1 and user3, and Team B contains user2 and user4.  The Friends tag actually includes user1, user2, user3, and user4 (all entries stacked).
+
+**Some Notes:**
+- There is no requirement to define the group before or after the URLs that are defined.
+- Tags associated with a group that are not used are just ignored.
+- Reuse of the same group assignment stacks it's values (it does not replace them)
 ## Expanding Configuration Sources
 The TEXT based configuration also supports the keyword `include` which allows you to pull more configuration down from other locations. For example:
