Update a conda-forge package

Find the feedstock for the recipe and clone it.

https://github.com/conda-forge/PACKAGENAME-feedstock

In recipe/meta.yaml increase the version number and update the sha256 (vi - daw) by going to pypi -> Download files -> Click on view hashes next to the .tar.gz file and copy the sha256

May also need to re-render the feedstock (https://conda-forge.org/docs/maintainer/updating_pkgs.html#rerendering-feedstocks)

$ conda install -c conda-forge conda-smithy

$ conda smithy rerender -c auto

Upload a package to conda forge

Fork https://github.com/conda-forge/staged-recipes

git clone staged-recipes # from your directory

$ git checkout -b shiny-new-feature
