+# Exercise 2
+
+In this exercise, you will create a new freestyle job and configure it to build with parameters. You'll also have a look at the Jenkins home directory to inspect the directory structure representing the job.
+
+## Defining, Configuring and Organizing a Job
+
+1. From the dashboard, click the "New Item" button.
+2. Enter the item name "my-freestyle-job" and select "Freestyle project". Press the "OK" button.
+3. In the job configuration, define the option to only keep the last 2 builds. Provide the description "A simple freestyle job". Upon building the project, a String parameter named `MESSAGE` should be provided. Press the "Save" button.
+4. Trigger a new build by pressing the "Build with Parameters" button. Enter a value for the `MESSAGE` parameter. The build should finish successfully. Locate the provided parameter value in the build information.
+5. Run the build two more times. What do you see?
+6. Create a new view named "test". Add the job to the view.
+7. Create a new folder named "freestyle" as part of the view. Move the job into the folder.
+8. Locate the build information in `$JENKINS_HOME`. Inspect the directory structure.

+The build history only stores the previous two builds.

+Create a new view.

+
+After adding the job to the view, it will show up in a separate tab.

+Create a new folder.

+
+The job became a child of the folder after moving it there.

+Navigating to the `job` directory under the Jenkins Home reveals the build history.
