 ## Binary installation
 
-This section describes how to compile and install the binary packages built from the robotology-superbuild on conda on Windows, macOS and Linux. 
-The binary packages are hosted in the [`robotology` conda channel](https://anaconda.org/robotology) . Only packages that are built as part of the profiles and options that are supported on Conda (see [documentation on CMake options](cmake-options.md)) are available as conda binary packages in the `robotology` channel.

+Depending on the speficic package, the binary packages are hosted either in [`conda-forge`](https://anaconda.org/conda-forge) or [`robotology`](https://anaconda.org/robotology). Only packages that are built as part of the profiles and options that are supported on Conda (see [documentation on CMake options](cmake-options.md)) are available as conda binary packages.

+The following conda platforms are supported by all packages of the robotology-superbuild:
+
+* `linux-64` (Linux on x86-64)
+* `osx-64` (macOS on x86-64)
+* `win-64` (Windows on x86-64)
+
+Some packages are also available for:
+* `linux-aarch64` (Linux on ARM 64-bit)
+* `osx-arm64` (macOS on ARM 64-bit)
+
+If you need a binary package on a platform in which it is not available, feel free to [open an issue](https://github.com/robotology/robotology-superbuild/issues/new) requesting it.

 Even if you are not using `mambaforge` and you are using instead a different `conda` distribution, to follow the instructions on this document you need to install the `mamba` package in your `base` environment. [`mamba`](https://github.com/mamba-org/mamba) is a re-implementation of some functionalities of the `conda` package manager, that is much faster.

+### Create an environment
 Differently from `apt` and `homebrew`, the `conda` package manager is an `environment`-oriented package manager, meaning that packages are not 
 installed in some global location, but rather you install packages in an `environment` (that is just a directory in your filesystem), so that you
 can easily have multiple different environments with different packages installed on your system. To read more about this, check https://docs.conda.io/projects/conda/en/4.6.1/user-guide/tasks/manage-environments.html .
