 ### Course material ###
 
-The course material is meant to be read part by part from start to finish. To get a passing grade, you have to do every exercise. The material contains exercises, which are placed so that the preceding material provides enough information for solving each exercise. Do the exercises as you go through the material. As you progress further, you will be increasingly searching for information on the internet. You should also supplement your knowledge with the [official documentation](https://kubernetes.io/docs/home/)!

-### Exercises ###
-
-Complete all of the exercises to receive a passing grade.
-
-Make a repository on GitHub and publish your solutions in clearly ordered files/folders. If you need help using Git, you should refer to their [guide](https://guides.github.com/activities/hello-world/). Make sure that the repository is available to me. We prefer public repositories, but if you want to keep your experience secret, you can create a private repository and add [Jakousa](https://github.com/Jakousa) as a collaborator.
-
-Most of the exercises will require you to write code or publish something to Docker Hub. If you are unsure what to submit, you can ask for help in the course chat.
-
-A system for detecting plagiarism is used to check exercises submitted to GitHub. If multiple students hand in the same code, the issue is handled according to the [policy on plagiarism](https://studies.helsinki.fi/instructions/article/what-cheating-and-plagiarism) of the University of Helsinki.
-
-There are multiple exercises in each part. After you have completed **all** of the exercises for a part, use the [submission system](https://studies.cs.helsinki.fi/stats/courses/kubernetes2024). Note that you can **not** edit a submission, so mark all as completed.

-To deploy an image, we need the cluster to have access to the image. By default, Kubernetes is intended to be used with a registry. K3d offers `import-images` command, but that won't work when we switch to non-k3d solutions. We will use the familiar registry _Docker Hub_, which we also used in [DevOps with Docker](http://devopswithdocker.com/). If you've never used Docker Hub, it is the place where the Docker client defaults to. E.g. when you run `docker pull nginx`, the nginx image comes from Docker Hub. See the course [DevOps for Docker](https://devopswithdocker.com/) for further details e.g. on pushing your images to Docker Hub if needed.

+It is also possible to use local images with k3d, but that won't work with non-k3d solutions. If you want to try using local images, use `k3d image import <image-name>`. Then you must edit the deployment's [imagePullPolicy](https://kubernetes.io/docs/concepts/containers/images/#image-pull-policy) from the default `Always` to `IfNotPresent` or `Never` to allow the local image to be used. The deployment can be edited after creation with `kubectl edit deployment <deployment-name>`.
