 =====
 
+With Pixi
+---------
+
+Pixi is a modern, extremely fast, frontend for conda packages and environments.
+First, `install pixi`_.
+Then, configure pixi to use bioconda in addition to it's default (`conda-forge`_)::
+
+  pixi config set default-channels '["conda-forge", "bioconda"]'
+
+Afterwards, you can install any package from bioconda globally::
+
+  pixi global install <somepackage>
+
+or locally into an environment associated with a directory::
+
+  cd myproject
+  pixi init
+  pixi add <somepackage>
+
+While globally installed packages are available everywhere on your system,
+locally installed packages are only available when you activate the associated
+environment via::
+
+  pixi shell
+
+in the respective directory.
+For more options and details see the `pixi documentation <https://pixi.sh>`__.
