-If you give a `--watch` or `-w` argument, task will watch for files changes
+By default, Task just redirect the STDOUT and STDERR of the running commands
+to the shell in real time. This is good for having live feedback for log
+printed by commands, but the output can become messy if you have multiple
+commands running at the same time and printing lots of stuff.
+
+To make this more customizable, there are currently three different output
+options you can choose:
+
+- `interleaved` (default)
+- `group`
+- `prefixed`
+
+ To choose another one, just set it to root in the Taskfile:
+
+ ```yml
+version: '2'
+
+output: 'group'
+
+tasks:
+  # ...
+ ```
+
+ The `group` output will print the entire output of a command once, after it
+ finishes, so you won't have live feedback for commands that take a long time
+ to run.
+
+ The `prefix` output will prefix every line printed by a command with
+ `[task-name] ` as the prefix, but you can customize the prefix for a command
+ with the `prefix:` attribute:
+
+ ```yml
+version: '2'
+
+output: prefixed
+
+tasks:
+  default:
+    deps:
+      - task: print

+```
+
+## Watch tasks

+If you give a `--watch` or `-w` argument, task will watch for file changes
 and run the task again. This requires the `sources` attribute to be given,
 so task know which files to watch.
