 OpenMS is an open-source, C++ framework for analyzing large volumes of mass spectrometry data. It has been specially designed for analyzing high performance LC-MS data but over recent times, has been extended to analyze data generated by other techniques.
 
 ```{note}
-OpenMS in recent times has been expanded to support a wide variety of mass spectrometry experiments. To design your analysis solution, [contact the OpenMS team](https://openms.github.io/community/) today.
