The Yocto Project layer ecosystem
It is convenient to create a layer. To make all the available layers easier to access, the OpenEmbedded community has developed an index, available at http://layers.openembedded.org, where most of them can be found. An example of its Layers tab is shown as follows:

Another convenient use case for the OpenEmbedded Layer Index website is to search for a specific software type or recipe. The OpenEmbedded Layer Index can save the day by allowing us to search for the following:
- Machines
- Distributions
- Layers
- Recipes
- Classes
The bitbake-layers
tool also supports the use of the OpenEmbedded Layer Index. For example, to add the meta-oe
layer, we can use the following command:
