+## Including other Taskfiles
+
+If you want to share tasks between different projects (Taskfiles), you can use

+```yaml
+version: '2'
+
+includes:
+  docs: ./documentation # will look for ./documentation/Taskfile.yml
+  docker: ./DockerTasks.yml
+```
+
+The tasks described in the given Taskfiles will be available with the informed
+namespace. So, you'd call `task docs:serve` to run the `serve` task from
+`documentation/Taskfile.yml` or `task docker:build` to run the `build` task
+from the `DockerTasks.yml` file.
