To start working with Spectrum, you need:
* xref:../installation/binary-cache.adoc[Set up the binary cache] to speed up the build process.
* xref:../installation/getting-spectrum.adoc[Build Spectrum] from the source.
* xref:../installation/b4.adoc[Install and configure the b4 utility] to be able to work with patches.
TIP: Currently, Spectrum works only on x86-64. AAarch64 support is in
development. If you have the configuration layer, you can
xref:../development/build-configuration.adoc[configure the build] to be able to
work with specific devices.
== Uninstalling and Updating
Currently, there is no implementation for a software update.
You can replace Spectrum by installing another OS.
