Building and booting
====================

Now it's time to download and configure the necessary source code.
Then we'll build it and get it to boot.
Firstly follow the **Building** steps for your Halium version.
Secondly, proceed with the final **Install and boot** section.

Deprecated building methods
===========================

In the past there used to be three separate porting methods called:

- Full system image method
- Halium boot method
- Standalone kernel method

For modern devices, this is much simplified. Full system was only really applicable on Halium 7.1 and 9.0 and Halium-boot worked on Halium 9.0. Nowadays there is just The One method that's described in this porting guide and what used to be called "Standalone method".
