+- ctr: CLI for containerD, not very user friendly and mostly for debugging
+	- It is advised to use nerdctl instead
+- nerdctl: provides docker-like CLI for containerd, supports docker compose, supports newest features in containerD (encrypted container images, lazy pulling...)
+- crictl: provides a CLI for CRI-compatible container runtimes, installed separately, used to inspect and debug container runtimes (not to create containers ideally), works across different runtimes
+	- `crictl pods` shows pods
+	- `crictl --runtime endpoint` enables you to specify a runtime endpoint (or use CONTAINER_RUNTIME_ENDPOINT env var)
+	- other commands are similar to docker
+## Glossary
+- CRI: Container Runtime Interface
+	- Kubernetes originally only worked for Docker but then introduced the CRI to be more abstract and allow all sorts of container runtimes
+- OCI: Open Container Initiative
+	- imagespec: specification on how an image should be build
+	- runtimespec: standards on how a container runtime shall be deployed
