 # Cloud Native Glossary
 
-The Cloud Native Glossary aims to make the cloud native space — which is notorious for its complexity — simpler for people by making it easier to understand, 
-not only for technologists but also for people on the business side. 
-To achieve that, we focus on simplicity (e.g., simple language free from buzzwords, examples anyone using technology can relate to, leaving unnecessary details out). 
-The Glossary is a project led by the CNCF Business Value Subcommittee (BVS).
