# Introduction
|
|
|
|
Typically you start by using an existing distribution, then override some variables to define which software you want or don't want and how to configure them.
|
|
|
|
|
|
## Add new software
|
|
|
|
When needed you can write a new recipe to add a specific software that is not in Yocto recipes.
|
|
|
|
|
|
## Customize existing recipe
|
|
|
|
To customize an existing recipe, you have to create a folder and a `.bbappend` file with the same name as the recipe:
|
|
```raw
|
|
$POKY
|
|
└─ meta
|
|
└─ recipes-devtools
|
|
└─ apt
|
|
└─ apt_0.9.9.4.bb => Original recipe
|
|
|
|
$LAYER
|
|
└─ recipes-*
|
|
└─ apt
|
|
└── apt_0.9.9.4.bbappend => Override
|
|
``` |
