Ubuntu Core Explanation guides

Our explanatory and conceptual guides are written to provide a better understanding of how Ubuntu Core works and how it can be used and configured. They enable you to expand your knowledge and become better at Ubuntu Core.

Explanation guides Why it does what it does
Snaps in Ubuntu Core Discover which snaps Ubuntu Core is built upon
Refresh control Updates that are finely managed and controlled
Security and sandboxing Understanding security policies and configuration

For a simpler place to start your Ubuntu Core journey, our tutorials section contains step-by-step tutorials to help outline what Ubuntu Core is capable of while helping you achieve specific aims, such as installing Ubuntu Core or building a custom image for your device.

If you have a specific goal, but are already familiar with Ubuntu Core, our How-to guides have more in-depth detail than our tutorials and can be applied to a broader set of applications. They’ll help you achieve an end-result but may require you to understand and adapt the steps to fit your specific requirements.

Take a look at our Reference section when you need to know which options can be used, what functions the API supports, which rescue modes are supported and the contends of gadget.yaml.
