+# About Greenmask
+
+## Dump anonymization and synthetic data generation tool
+
+**Greenmask** is a powerful open-source utility that is designed for logical database backup dumping,
+anonymization, synthetic data generation and restoration. It has ported PostgreSQL libraries, making it reliable.
+It is stateless and does not require any changes to your database schema. It is designed to be highly customizable and
+backward-compatible with existing PostgreSQL utilities, fast and reliable.
+
+
+## Key features
+
+* **[Deterministic transformers](built_in_transformers/transformation_engines.md/#hash-engine)**
+  — deterministic approach to data transformation based on the hash
+  functions. This ensures that the same input data will always produce the same output data. Almost each transformer
+  supports either `random` or `hash` engine making it universal for any use case.
+* **[Dynamic parameters](built_in_transformers/dynamic_parameters.md)** — almost each
+  transformer supports dynamic parameters, allowing to parametrize the
+  transformer dynamically from the table column value. This is helpful for resolving the functional dependencies
+  between columns and satisfying the constraints.
+* **[Transformation validation and easy maintainable](commands/validate.md)** - During
+  configuration process, Greenmask provides validation
+  warnings, data transformation diff and schema diff features, allowing you to monitor and maintain transformations
+  effectively
+  throughout the software lifecycle. Schema diff helps to avoid data leakage when schema changed.
+* **[Partitioned tables transformation inheritance](configuration.md/?h=partition#dump-section)**
+  — Define transformation configurations once and apply them to all
+  partitions within partitioned tables (using `apply_for_inherited` parameter), simplifying the anonymization process.
+* **Stateless** - Greenmask operates as a logical dump and does not impact your existing database schema.
+* **Cross-platform** - Can be easily built and executed on any platform, thanks to its Go-based architecture,
+  which eliminates platform dependencies.
+* **Database type safe** - Ensures data integrity by validating data and utilizing the database driver for
+  encoding and decoding operations. This approach guarantees the preservation of data formats.
+* **Backward compatible** - It fully supports the same features and protocols as existing vanilla PostgreSQL utilities.
+  Dumps created by Greenmask can be successfully restored using the pg_restore utility.
+* **Extensible** - Users have the flexibility
+  to [implement domain-based transformations](built_in_transformers/standard_transformers/cmd.md/)
+  in any programming language or
+  use [predefined templates](built_in_transformers/advanced_transformers/index.md).
+* **Integrable** - Integrate seamlessly into your CI/CD system for automated database anonymization and
+  restoration.
+* **Parallel execution** - Take advantage of parallel dumping and restoration, significantly reducing the time required
+  to deliver results.
+* **Provide variety of storages** - offers a variety of storage options for local and remote data storage,
+  including directories and S3-like storage solutions.
+* **[Pgzip support for faster compression](commands/dump.md/?h=pgzip#pgzip-compression)** — by
+  setting `--pgzip`, it can speeds up the dump and restoration
+  processes through parallel compression.
+
+
+## Use cases
+
+Greenmask is ideal for various scenarios, including:
+
+* **Backup and restoration**. Use Greenmask for your daily routines involving logical backup dumping and restoration. It
+  seamlessly handles tasks like table restoration after truncation. Its functionality closely mirrors that of pg_dump
+  and pg_restore, making it a straightforward replacement.
+* **Anonymization, transformation, and data masking**. Employ Greenmask for anonymizing, transforming, and masking
+  backups, especially when setting up a staging environment or for analytical purposes. It simplifies the deployment of
+  a pre-production environment with consistently anonymized data, facilitating faster time-to-market in the development
+  lifecycle.
