+# Requirements
 MAGICIAN is a Snakemake pipeline that uses conda or mamba to manage dependencies.
 Thus, it primarily requires Snakemake and conda or mamba to be used (mamba is recommended). \

 In order to get started with MAGICIAN, simply clone the repository:
 ```commandline
 git clone https://github.com/KatSteinke/magician
 ```
 
 You will also have to adapt the config file given under [config/default_config.yml](config/default_config.yml).

 MAGICIAN requires the following files to run:
 * genome sequences of the organisms the simulated community should consist of, in genbank or fasta format
 * a tab-separated file of sample distributions.
