You cannot use the donnemartin/system-design-primer repository commercially because it currently has no explicit license stated. This repository, which boasts an impressive 373,083 stars and is actively maintained (last pushed just 19 days ago), is labeled with "NOASSERTION" regarding its license. This means that the authors have not supplied any licensing information, leaving the legal usage rights ambiguous.

Implications:

Without a clear license, you are typically not granted rights to modify, distribute, or use the content commercially. Usage would fall into a legal gray area, which could pose risks. If you plan to use it for anything beyond personal or educational purposes, it's advisable to seek an alternative with a definitive license or to contact the repository owner for clarification.
