 ## Breaking changes in v2.x of the module
 Due to breaking changes in Snowflake provider and additional code optimizations, **breaking changes** were introduced in `v2.0.0` version of this module.
 
-Lst of code and variable (API) changes:
+List of code and variable (API) changes:
 - Switched to `snowflake_grant_ownership` resource instead of provider-removed `snowflake_role_ownership_grant`
 - Switched to `snowflake_database_role` module to leverage new `database_roles` mechanism
 - `default_roles` and `custom_roles` are now combined and managed by single module
-- `create_default_roles` variable was renamed to `create_default_databse_roles`
+- `create_default_roles` variable was renamed to `create_default_database_roles`
 - `roles` variable map received following additions:
   - `all_privileges` - optional, bool
   - `on_all` - optional, bool, defaults to false
