-Atlas tools help developers manage their database schemas by applying modern DevOps principles.
-Contrary to existing tools, Atlas intelligently plans schema migrations for you, based on your desired state.
+Atlas is a language-agnostic tool for managing and migrating database schemas using modern DevOps principles.
+It offers two workflows:
 
-### Supported databases: 
-* MySQL
-* MariaDB
-* PostgreSQL
-* SQLite
-* TiDB
-* SQL Server
-* ClickHouse
-* CockroachDB
+- **Declarative**: Similar to Terraform, Atlas compares the current state of the database to the desired state, as
+defined in an [HCL], [SQL], or [ORM] schema. Based on this comparison, it generates and executes a migration plan to 
+transition the database to its desired state.
 
-### Docs
-* [Provider Docs](https://registry.terraform.io/providers/ariga/atlas/latest/docs)
-* [Atlas Docs](https://atlasgo.io)
+- **Versioned**: Unlike other tools, Atlas automatically plans schema migrations for you. Users can describe their desired
+database schema in [HCL], [SQL], or their chosen [ORM], and by utilizing Atlas, they can plan, lint, and apply the
+necessary migrations to the database.
