Macaulay2
=========
Macaulay2 is a system for computing in commutative algebra, algebraic geometry
and related fields. The system was originally written by Dan Grayson and Mike
Stillman. David Eisenbud joined the project a number of years ago, and many
users are writing packages for the system, and some are contributing source
code. See our web page [Macaulay2.com](https://macaulay2.com/) for more details and for
downloading binary releases.
The structure of this directory is as follows:
* `M2`: contains everything needed by a user to build Macaulay2.
* `bugs`: contains older bug reports.
See `CITATION.cff` for information about citing Macaulay2.
### Contributions
Contributions to the code of Macaulay2 are welcome.
The source code is available via our GitHub [repository](https://github.com/Macaulay2/M2),
where you can also report bugs via the [issue tracker](https://github.com/Macaulay2/M2/issues).
For brief instructions, see [here](https://github.com/Macaulay2/M2/wiki/Git-for-Macaulay2-Contributors).
To start working on an existing github "issue", volunteer to work on it, so
you can get "assigned" to the issue, thereby preventing duplication of
effort.
To make a contribution, submit a "pull request" on github. If the
contribution involves changing an existing package in a non-trivial way, we
will normally contact the authors to get their approval of the change. If a
new package with mathematical content is submitted, it will normally be
accepted if it can be installed with `installPackage` and the tests pass as
determined by `check`, in the latest version of Macaulay2.
