[[https://conda.io/docs/|Conda]] packages for Linux & macOS are available through [[https://conda-forge.github.io/|conda-forge]].

= Setting Up =

In short: Install `sage` from [[https://conda-forge.org|conda-forge]].

 * Download and install [[https://github.com/conda-forge/miniforge/#mambaforge|Mambaforge]].
   i.e., open a Terminal,
     `curl -L -O https://github.com/conda-forge/miniforge/releases/latest/download/Mambaforge-$(uname)-$(uname -m).sh`

     `sh Mambaforge-$(uname)-$(uname -m).sh`
 * Create a "sage" environment and pick a version of SageMath, i.e., open a new terminal and `mamba create -n sage sage=9.3`
 * To run SageMath, activate the environment you just created and run SageMath, i.e., `source activate sage` and `sage`

= Maintenance =

The packages necessary to run sage are developed on the github pages of conda-forge. The actual [[https://github.com/conda-forge/sage-feedstock/tree/master/recipe|sage package]] and many of its dependencies are maintained by Isuru Fernando (and a few volunteers).

= Conda for Sage Developers =

You can develop Sage without building any of its dependencies (experimental) --- on my machine this takes 5 minutes. Assume you obtained Sage source tree and changed to its root.

== Windows ==

There is likely not going to be a working package in the near future, see https://groups.google.com/d/msg/sage-devel/wyaV8x5qolI/jVS4DKBvCAAJ.
