Macaulay2 is an interpreted, dynamically typed programming language intended to support research in algebraic geometry and commutative algebra through open sourced software.

Here is an example of how to compute the minimal free resolution of the [_twisted cubic_](docs/example):
#### Code:
```
R = QQ[x, y, z, w]; -- defines a ring
I = monomialCurveIdeal(R, {1, 2, 3})
C = res I -- computes the resolution
```
-- quick usage information
? monomialCurveIdeal
-- details and examples
help monomialCurveIdeal
-- documentation on the web
viewHelp monomialCurveIdeal
#### Result:
{% M2 index %}
R = QQ[x, y, z, w];
I = monomialCurveIdeal(R, {1, 2, 3})
C = res I
{% endM2 %}

The recommended IDE for using Macaulay2 in research is [Emacs](https://www.gnu.org/software/emacs/)
(here is a [cheat sheet](https://www.gnu.org/software/emacs/refcards/pdf/refcard.pdf)).
Community plugins are also available for
[Vim](https://github.com/Macaulay2/M2/tree/master/M2/Macaulay2/editors/vim),
[Atom](https://github.com/Macaulay2/language-macaulay2),
[VSCode](https://github.com/coreysharris/vscode-macaulay2), and
[Sublime](https://github.com/Macaulay2/M2/wiki/Using-Macaulay2-with-Sublime).

Development of Macaulay2 by [Daniel R. Grayson](https://faculty.math.illinois.edu/~dan/)
and [Michael E. Stillman](https://math.cornell.edu/michael-e-stillman) has been funded
by the National Science Foundation since 1992. We also acknowledge our many
[contributors](contributors), [software libraries](libraries) used by Macaulay2,
as well as [Macaulay](http://www.math.columbia.edu/~bayer/Macaulay/),
the predecessor of Macaulay2 written by Dave Bayer and Michael Stillman.
The namesake of Macaulay2 is Francis Macaulay FRS.
