+
+Documentation available: [http://matplotlib.org/cmocean/](http://matplotlib.org/cmocean/).
+
+Besides Python, the cmocean colormaps are also available for:
+
+* For [MATLAB](http://www.mathworks.com/matlabcentral/fileexchange/57773-cmocean-perceptually-uniform-colormaps) by [Chad Greene](http://www.chadagreene.com/)
+* For R: [Oce](http://dankelley.github.io/oce/) oceanographic analysis package by [Dan Kelley](http://www.dal.ca/faculty/science/oceanography/people/faculty/daniel-e-kelley.html) and [Clark Richards](http://clarkrichards.org/)
+* For [Ocean Data Viewer](https://github.com/kthyng/cmocean-odv)
+* For Generic Mapping Tools (GMT)  at [cpt-city](http://soliton.vm.bytemark.co.uk/pub/cpt-city/cmocean/index.html) and on [github](https://github.com/kthyng/cmocean-gmt)
+* For [Paraview](https://github.com/kthyng/cmocean-paraview) inspired by [Phillip Wolfram](https://github.com/pwolfram)
+* In [Plotly](https://plot.ly/python/cmocean-colorscales/)
+* Chad Greene's [Antartic Mapping Tools](http://www.mathworks.com/matlabcentral/fileexchange/47638-antarctic-mapping-tools) in Matlab uses `cmocean`
+
+
+To install:
+``pip install cmocean``
+
+To install with Anaconda:
+``conda install -c conda-forge cmocean``
+
+If you want to be able to use the `plots` submodule, you can instead install with:
+
+`pip install "cmocean[plots]"`
+
+which will also install `viscm` and `colorspacious`.
