-We want to support all software, but unfortunately time is limited.
-In the chart below, we have these categories (which don't really mean
-anything, but in the future should help us be more transparent about
-what we are able to support):
+Software installations
+----------------------
 
-* A: Full support and good documentation, installed for everyone,
-  installation should always work.
-* B: We install and provide best-effort documentation, but may be out
-  of date.  We only update the install and documentation on-demand.
-* C: Basic info, no guarantees
+We aim to help as many people as possible, but we can't do everything.
+For things we can't install for everyone, we can often provide
+instructions for how you can install it by yourself.
 
-If you know some application which is missing from this list but is
-widely in use (anyone else than you is using it) it would make sense
-install to ``/share/apps/`` directory and create a module file. Send
-your request to the tracker.  We want to support as much software as
-possible, but unfortunately we don't have the resources to do
-everything centrally.

-Software is generally easy to install if it is in `Spack
-<https://packages.spack.io/>`__ (check
-that package list page), a scientific software management and building
-system.  If it has easy-to-install Ubuntu packages,
-it will be easy to do via :doc:`singularity <../usage/singularity>`.
+Software is generally easy to install if it is in the `conda's
+conda-forge channel <https://anaconda.org/search>`__ (for almost any
+software, see our :doc:`conda guide </triton/apps/python-conda>`) or the

+software).  If it has easy-to-install Ubuntu packages, it will be easy
+to do via :doc:`singularity <../usage/singularity>` containers.

+We want to support all software, but unfortunately time is limited.
+If we tried to install everything perfectly, we would in practice not
+be able to support much.  Thus, we try to do the best we can for as
+many people as we can by defining these levels of support.  You don't
+have to know the levels: just ask for what you need, the levels are
+for us to organize our support internally.
