	Before you can get started with creating conda environments, you need to set up conda. Some clusters provide a centrally installed conda module and others require you to install conda yourself. The following table provides an overview of the necessary initial steps depending on the cluster.		Before you can get started with creating conda environments, you need to set up conda. Some clusters provide a centrally installed conda module and others require you to install conda yourself. The following table provides an overview of the necessary initial steps depending on the cluster.

			In general, there are three options for installing conda (Miniforge, Miniconda, Anaconda Distribution). We recommend the usage of Miniforge as it uses open source software packages by default. With the other two options, the default is to install packages from Anaconda's default channels which are subject to Anaconda's Terms of Service.

	If no conda module is available, you can install conda yourself. There are different options on how to do this but we recommend to install Miniforge. The installation is described below. Afterwards, conda and mamba commands can be used. The default channel is conda-forge.		If no conda module is available, you can install conda yourself.

 [https://conda.io/docs/index.html Conda] helps to manage software environments and packages. Installing software packages into independent environments improves programming flexibility and leads to a higher reproducibility of research results. A majority of the scientific software is available as conda package, which allows for convenient installations.
