Introduction¶

Getting Help¶

The latest release of wannier90 and documentation can always be found at https://www.wannier.org.

The development version may be cloned/downloaded from the official repository of the wannier90 code on GitHub (see https://github.com/wannier-developers/wannier90).

There is a wannier90 mailing list for discussing issues in the development, theory, coding and algorithms pertinent to MLWF. You can register for this mailing list by following the links at https://www.wannier.org/forum.html. Alternatively, for technical issues about the wannier90 code, check the official repository of wannier90 on GitHub where you may raise issues or ask questions about its functionalities.

Finally, many frequently asked questions are answered in Appendix FAQs. An expanded FAQ session may be found on the Wiki page of the GitHub repository at https://github.com/wannier-developers/wannier90/wiki/FAQ.
