-## About
-
-This software package includes a range of modules and subsystems to work
-with CrateDB and CrateDB Cloud efficiently.
-
-You can use CrateDB Toolkit to run data I/O procedures and automation tasks
-of different kinds around CrateDB and CrateDB Cloud. It can be used both as
-a standalone program, and as a library.
-
-It aims for [DWIM]-like usefulness and [UX], and provides CLI and HTTP
-interfaces, and others.
-
-
-## Features
-
-- **Capable:** Connect to the InfluxDB HTTP API, or read from an InfluxDB
-  TSM data directory directly.
-
-- **Versatile:** Use it as a command-line program, pipeline element,
-  or as a library within your own applications.
-
-- **Polyglot:** Support I/O operations between InfluxDB, any SQL database
-  supported by SQLAlchemy, file formats supported by pandas/Dask, and
-  the native InfluxDB line protocol (ILP), on both import and export
-  directions.
-
-
-## Synopsis

-primitive, which accepts a range of variants on its `SOURCE` and `TARGET`
-arguments, in URL formats.
