   In the near future we will start to provide a cookbook like tutorial in the [CSBlog](https://csbiology.github.io/CSBlog/).

  BioFSharp aims to be a user-friendly functional library for bioinformatics written in F#. It contains the basic data structures for common biological objects like amino acids and nucleotides based on chemical formulas and chemical elements.
