-- Reproducible dev environments
-- Testing in CI/CD environments
-- Better "Portability" of application code

 In reality we use containers and vm's together.  Containers run inside of VM's for better security and isolation, especially in cloud and multi tenant environments.

 ## What is Docker?
 
+- A tool to build and run containers
 - Written in GO
 - Uses Client/Server model with REST API (`docker cli` and `dockerd`)
 - Eco system of tools (Compose, Swarm, etc)
 - Public Image Registry (Dockerhub)
 - Docker client typically runs on same machine as server but doesn't have to

-## What is Docker?
-
-- A tool to build and run containers
-- Containers are exclusive to Linux
-- Docker engine runs containers using Linux features like:
-  - Namespaces
-  - cgroups
-  - Union file systems
-- Container runs from an image layered with base image and application code
-
+- Uses Linux kernal features like:
+    - Namespaces
+    - cgroups
+    - Union file systems
+- Containers are just processes
