To try Spectrum OS out or xref:../development/testing-patches.adoc[test patches], you need to build the system from the source.

In order to speed up the build process, set up the binary cache. After building Spectrum OS, you can install and configure the b4 utility to be able to work with patches.


TIP: Note that Spectrum OS currently works only on x86-64. AAarch64 support is in development.

Currently, there is no implementation for a software update.

You can replace the installation with some other OS.
