 [National Instruments](https://www.ni.com), the TDM format relies on the
 _technical data management_ data model and is employed by
 [LabVIEW](https://www.ni.com/de-de/shop/labview.html), LabWindows™/CVI™,
 Measurement Studio, SignalExpress, and [DIAdem](https://www.ni.com/de-de/shop/data-acquisition-and-control/application-software-for-data-acquisition-and-control-category/what-is-diadem.html).
-The [Record Evolution Platform](https://www.record-evolution.de/en/home-en/) uses TDMtermite to integrate measurement data into ETL processes. The TDMtermite library is available both as a command line tool and as a Python module. The Python module of TDMtermite enables data scientists to conveniently include TDM formats in their existing data pipelines by providing access to both raw data and metadata in terms of native Python objects.

 #### Installation with pip
 The package is also available via the [Python Package Index](https://pypi.org) at
 [TDMtermite](https://pypi.org/project/tdmtermite/). To install the latest version simply do
 ```Shell
 python3 -m pip install tdmtermite
 ```
 ##### Unix
 Note, that _python3_setuptools_ and _gcc version >= 10.2.0_ are required to
 successfully install and use it.
