Open Cube OS documentation

Welcome to the documentation center for Open Cube OS - the from-scratch x86_64 kernel with the oc> recovery shell.

Everything here is written against the real tree: command counts, interface tables and line statistics are machine-generated (make api-docs -> docs/data/*.json), and the manual pages cite the file that implements what they describe.

Start here

• Want to build it: Developer-Environment-EN then Building-from-Source-EN
• Want to extend it: L1-Overview-EN
• Architecture questions: Architecture-Overview-EN then the deep dives under Architecture-Guide-EN
• Something broke: Troubleshooting-Common-EN
