 A powerful command-line interface for managing and interacting with Weaviate vector databases directly from your terminal.
 
 ## Key Features

+- **Collections**: Create, batch, update, delete and get collection configurations
 - **Data Management**: Import, query, update and delete data with various search types (vector, keyword, hybrid)
 - **Multi-tenancy**: Manage tenants and their states across collections
 - **Backup & Restore**: Create and restore backups with support for S3, GCS and filesystem

 ## Core Commands
 
 - **create**: Create collections, tenants, backups or import data
+- **batch**: batch import a collection from a local file
 - **delete**: Remove collections, tenants or data
 - **update**: Modify collection settings, tenant states or data
 - **get**: Retrieve collection info, tenant details or shard status
