About conda-forge

conda-forge is a GitHub organization containing repositories of conda recipes. Thanks to some awesome continuous integration providers (AppVeyor, Azure Pipelines, CircleCI and TravisCI), each repository, also known as a feedstock, automatically builds its own recipe in a clean and repeatable way on Windows, Linux and OSX.

The built distributions are uploaded to anaconda.org/conda-forge and can be installed with conda. For example, to install a conda-forge package into an existing conda environment:

conda config --add channels conda-forge

conda config --set channel_priority strict

conda install <package-name>

Miniforge is an effort to provide Miniconda-like installers, with the added feature that conda-forge is the default channel. Unlike Miniconda, these support ARMv8 64-bit (formally known as `aarch64`).

For a package on conda-forge, I want to ...

Report an issue with a package

Search for the appropriate feedstock repository. The list of existing feedstocks is a good place to start.
Take a look to see if the issue has already been raised on the feedstock's issue tracker. Otherwise, create a new issue, providing appropriate information, such as your operating system, package versions and, a reproducible example of the problem. Even better, if you can automate the test in the conda recipe, it might be worth submitting a PR containing the test.
Can't find the feedstock? No worries, just raise the issue at conda-forge/conda-forge.github.io and we will make sure the right people see it.

Update a package

Search for the appropriate feedstock repository. The list of existing feedstocks is a good place to start.
Fork the feedstock you wish to update.
Create a new branch from the feedstock master branch.
Edit the recipe as desired. You may even consider adding yourself as a recipe maintainer.
Propose the change as a pull request. Your recipe will automatically be built on Windows, Linux, and OSX to test that it works, but the new distribution will not yet be available on the conda-forge channel.
Once the recipe is ready it will be merged. The recipe will then automatically be built and uploaded to the conda-forge channel.

Add a recipe

Fork conda-forge/staged-recipes
Create a new branch from the staged-recipes master branch.
Add a new conda recipe in a new "recipes/[your-package-name]" directory. There is an example of a well-written recipe in "recipes/example" you can copy. Further guidance on writing good recipes. You can also test the recipe locally.
Propose the change as a pull request. Your recipe will automatically be built on Windows, Linux, and OSX to test that it works, but the distribution will not yet be available on the conda-forge channel.
Once the recipe is ready it will be merged and a new "feedstock" repository will automatically be created for the recipe. The build and upload processes take place in the feedstock, and once complete the package will be available on the conda-forge channel.
