-# 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, 01-04: Install Jenkins as a Container
 
-_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.
+# Prerequisites
+You will need to have [Docker](https://docs.docker.com/get-docker/) installed on your local system.
 
-## 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.
