Please review the requirements in the Installation section above. IGraph/M is not compatible with your system. Please follow the installation instructions above carefully.

This message will be shown in the following situations: In the bug report include the output of IGraphM`Developer`GetInfo.

If you do find a problem, please open an issue on GitHub or write in the chatroom. However, I try not to release a new version until most problems I know of are fixed. IGraph/M is currently under development, and a few bugs are to be expected. UncompressД¬++ programmers should look at Development.md for additional information. Evaluate the following in Mathematica to get my email address: If you are interested in contributing, send me an email for guidance.

Implement entirely new functions in C++.

Expose more igraph library functions to IGraph/M (C++ knowledge required).

Implement new functions in pure Wolfram Language code.

Create examples for the documentation or edit the documentation.

Just test the package and try to find problems.

In order of increasing difficulty, help is needed with the following tasks: Update: Help wanted with editing documentation and writing unit tests! Only basic Mathematica knowledge is required for this.Д¬ontributions to IGraph/M are very welcome! Mathematica programmers of all levels of expertise can contribute. If you would like to help out with expanding the documentation, send me an email.ДЇor additional details about functions, or for paper references for the methods used, also check the igraph documentation pages. The documentation is not yet complete and contributions are very welcome. Or search for 'igraphm' in Mathematica's Documentation Center.
