+#40 - Handlers
+
+This exercise makes you use handlers to control flow execution.
+
+## Playbook creation
+Write a playbook following the given specs:
+* Run on host group `lab`
+* Install a web server (eg. `nginx` or `httpd`) on each host using the module adapted to the package manager of your hosts
+* Trigger a handler that starts the corresponding service (using appropriate module as well)
+
+## Validation
+Run the playbook and checks if the service is installed and started.
+
+There is a working playbook in `solution/solution.yml` (for an Alpine host)
