 ## Container (Singularity/Docker)
 For most uses, we recommend instead using a containerized installation with [Singularity](https://singularity.lbl.gov) or [Docker](https://www.docker.com). Containers allow to build entire computing environments, grouping all dependencies required to run the software. This in turn reduces the burden of installing dependencies manually and ensures reproducible behavior of the software. Singularity is generally preferred over Docker since it requires less permission, and can thus be imported from most computing environment (e.g. high performance computing clusters such as Compute Canada.)

 ## Neurodesk
 RABIES is also made available on the [Neurodesk platform](https://neurodesk.github.io/), as part of the [built-in tools](https://neurodesk.github.io/applications/) for neuroimaging. The Neurodesk platform allows for an entirely browser-based neuroimaging computing environment, with pre-built neuroimaging tools from the community, and aims at reducing needs for manual development of computing environments and at improving reproducible neuroimaging. More details on Neurodesk here <https://neurodesk.github.io/docs/>.
