For questions related to Sitecore Content Serialization using the Sitecore CLI or Sitecore for Visual Studio.

Sitecore Content Serialization (SCS) is a system for serializing, sharing, and deploying content items, as well as keeping them in version control. This functionality is designed to help teams of developers that work on the same Sitecore solution to synchronize database changes between their individual development environments.

This feature has been introduced with Sitecore 10 release. In the earlier versions, developers used multiple tools such as TDS, Unicorn to sync/serialize Sitecore items.

Sitecore Content Serialization (SCS) comes with JSON based configurations in which we have certain options to configure/choose while including and excluding the items.

More information on Sitecore Content Serialization can be found in Sitecore documentation.
