 ## Containers are just processes
 
-If you don't take anything else away from this talk, I hope you walk away with a better understanding of this fundamental.  As far as the OS* is concerned, a container is just another process/set of processes to the operating system.

-<p style="font-size:10px;max-width:20vw;line-height:1.3em;">*This is only strictly true on Linux.  Running Docker on Mac/Windows requires Docker Desktop which actually creates and manages a Linux VM.  Your containers actually run inside of this VM.</p>

+# Container runtimes vs. container engines
+> While a container runtime is responsible for running containers, a container engine is a broader system that manages even more of the life cycle of containers, including image distribution, container orchestration, and runtime management. 
+
+> One common misconception is that Docker and container runtimes are the same. While Docker Engine includes a container runtime, it also offers a suite of tools for building, shipping, and running containerized applications, making it much more than just a runtime.

+# Docker: Runtime or engine?!?
+Docker Engine uses containerd for managing the container lifecycle, which includes creating, starting, and stopping containers. By default, containerd uses runc as its container runtime.
+
+<br/>
+
+## Wait, aren't they all runtimes?  If docker engine uses containerd and containerd uses runc, whats the deal?

+### 🔧 High-Level Definitions
+
+- Runtime = Low-level component that actually creates and runs containers.
+
+- Engine = Higher-level component that manages the full container lifecycle (build, run, network, volume, etc.) and talks to the runtime.
+
+---
+transition: fade-out
+---
+
+# Breakdown
+
+Docker CLI & Docker API rely on Docker Engine under the hood
+-> Docker Engine is an engine (High level functionality like managing networking, images, registries, etc)
+-> Docker Engine relies on `containerd` runtime to manage lifecyle of containers
+-> `containerd` uses `runc` as the runtime to run containers
+
+## Super clear?!
+The `engine` is the higher level component responsible for orchestration and lifecycle management.
+
+The `runtime` is a component responsible for the low level process execution/isolation.

+# What is Docker Desktop?
+Docker Desktop is an integrated container development environment for Windows and macOS. It's a packaged product that includes several components:
+
+| Component                      | Description                                                                 |
+| ------------------------------ | --------------------------------------------------------------------------- |
+| **Docker Engine**              | The actual engine that runs and manages containers.                         |
+| **containerd** + **runc**      | The container runtime stack used by Docker Engine.                          |
+| **VM (e.g. `docker-desktop`)** | On macOS and Windows, Linux containers need to run inside a lightweight VM. |
+| **Docker CLI**                 | Command-line tool to interact with Docker Engine.                           |
+| **Docker Compose**             | Tool for defining and running multi-container apps.                         |
+| **GUI**                        | Visual interface for managing containers, volumes, settings, etc.           |
+| **Kubernetes** (optional)      | Comes with optional single-node K8s cluster for testing.                    |
+| **Networking components**      | Manages host-to-VM and container networking.                                |
