+# Learning Jenkins, 02-01: Your First Jenkins Job
+In this lesson you create your first job.
+
+Use the console to create a freestyle job with one build step.
+
+# MacOS, Linux, and Docker
+If you are running Jenkins on MacOS, Linux, or Docker:
+
+1. Select the `Execute shell` build step.
+2. Enter the following for the command:
+```
+echo "Hello, Jenkins"
+```
+
+# Troubleshooting Errors
+If you select the `Execute Windows batch command` build step, you will see an error similar to the following:
+```
+Building in workspace /var/jenkins_home/workspace/hello

+
+This is because the program Jenkins uses with the `Execute Windows batch command` build step is not available on your system.
+
+To fix this error, use the `Execute shell` build step as described above.

-# Learning Jenkins
-This is the repository for the LinkedIn Learning course `Learning Jenkins`. The full course is available from [LinkedIn Learning][lil-course-url].
+# Learning Jenkins, 02-01: Your First Jenkins Job
+In this lesson you create your first job.
 
-_See the readme file in the main branch for updated instructions and information._
-## Instructions
-This repository has branches for each of the videos in the course. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add `/tree/BRANCH_NAME` to the URL to go to the branch you want to access.
+Use the console to create a freestyle job with one build step.
 
-## Branches
-The branches are structured to correspond to the videos in the course. The naming convention is `CHAPTER#_MOVIE#`. As an example, the branch named `02_03` corresponds to the second chapter and the third video in that chapter. 
-Some branches will have a beginning and an end state. These are marked with the letters `b` for "beginning" and `e` for "end". The `b` branch contains the code as it is at the beginning of the movie. The `e` branch contains the code as it is at the end of the movie. The `main` branch holds the final state of the code when in the course.

+If you are running Jenkins on a Windows system:
 
-When switching from one exercise files branch to the next after making changes to the files, you may get a message like this:
+1. Select the `Execute Windows batch command` build step
+2. Enter the following for the command:
+```
+echo "Hello, Jenkins"
+```
 
-    error: Your local changes to the following files would be overwritten by checkout:        [files]
-    Please commit your changes or stash them before you switch branches.
-    Aborting
+[Follow this link for more details on Windows](WINDOWS.md)
 
-To resolve this issue:
-	
-    Add changes to git using this command: git add .
-	Commit changes using this command: git commit -m "some message"
