 ## Prerequisites
 
-This pipeline was developed using [CASA](https://casa.nrao.edu/casa_obtaining.shtml) [v5.4.2-5](https://casa.nrao.edu/download/distro/casa/release/el7/casa-release-5.4.2-5.el7.tar.gz). It also requires the [Analysis Utilities](https://casaguides.nrao.edu/index.php/Analysis_Utilities) library. All of the Python dependencies are listed in [environment.yml](https://github.com/AMIGA-IAA/hcg_hi_pipeline/blob/master/conda_env.yml) which defines a [Conda](https://docs.conda.io/en/latest/) environment that can be constructed as described [here](https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#creating-an-environment-from-an-environment-yml-file).
