-## Watch tasks (experimental)

-If you give a `--watch` or `-w` argument, task will watch for files changes
+Dry run mode (`--dry`) compiles and steps through each task, printing the commands
+that would be run without executing them. This is useful for debugging your Taskfiles.
+
+## Ignore errors
+
+You have the option to ignore errors during command execution.
+Given the following Taskfile:
+
+```yml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - exit 1
+      - echo "Hello World"
+```
+
+Task will abort the execution after running `exit 1` because the status code `1` stands for `EXIT_FAILURE`.
+However it is possible to continue with execution using `ignore_error`:
+
+```yml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - cmd: exit 1
+        ignore_error: true
+      - echo "Hello World"
+```
+
+`ignore_error` can also be set for a task, which mean errors will be supressed
+for all commands. But keep in mind this option won't propagate to other tasks
+called either by `deps` or `cmds`!
+
+## Output syntax
+
+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
+        vars: {TEXT: foo}
+      - task: print
+        vars: {TEXT: bar}
