+# Exercise 3
+
+In this exercise, you will configure the job to build based on a cron definition. Moreover, you will create downstream job that should be built automatically if the upstream job is successful.
+
+## Configuring Build Triggers and Steps for a Job
+
+1. Add a default value for the build parameter named `MESSAGE` e.g. `Hello World!`.
+2. Create a build trigger that builds the project every minute.
+3. Add a build step that executes the shell command `echo "Message: $MESSAGE"`. The message is value of the parameter.
+4. After a minute the first execution should have been triggered. Check the log output of the build and find the rendered message.
+5. Create another freestyle project named `downstream-job` in the same folder.
+6. Configure the initial job to execute the `downstream-job` if it was stable.
