-# Slack Data Import Tool
-
-The slack import tool has been shifted to the Zulip server repository.
-The data can be converted from slack data format to zulip data format
-using the command `./manage.py convert_slack_data`.
-
-The procedure to use this would be:
-
-1. `./manage.py convert_slack_data <slack_zip_file> <realm_name> --output <output_dir>`.
-2. To import this converted data into a new Zulip instance, use
-    `./manage.py import --destory-rebuild-database <output_dir>`.
-3. To import this converted data into an existing Zulip instance (with multiple realms)
-   use `./manage.py import --import-into-nonempty <output_dir>`.
