+This call matches the `start:*` task and the string "foo" is captured by the
+wildcard and stored in the `.MATCH` variable. We then index the `.MATCH` array
+and store the result in the `.SERVICE` variable which is then echoed out in the
+cmds:
+
+```shell
+$ task start:foo
+Starting foo
 ```
 
+You can use whitespace in your arguments as long as you quote the task name:
+
 ```shell
-# This call matches the "echo-*" task and the string "hello" is captured by the
-# wildcard and stored in the .MATCH variable. We then index the .MATCH array and
-# store the result in the .TEXT variable which is then echoed out in the cmds.
-$ task echo-hello
-hello
-# You can use whitespace in your arguments as long as you quote the task name
-$ task "echo-hello world"
-hello world
-# And you can pass multiple arguments
-$ task run-foo-bar
-foo bar
-```
-
-If multiple matching tasks are found, an error occurs. If you are using included
-Taskfiles, tasks in parent files will be considered first.
+$ task "start:foo bar"
+Starting foo bar

+
+If multiple matching tasks are found, the first one listed in the Taskfile will
+be used. If you are using included Taskfiles, tasks in parent files will be
+considered first.

+```shell
+$ task start:foo:3
+Starting foo with 3 replicas
