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

  ## Installation
  
  **From Nuget.org:**
  
  You can get the stable versions of all BioFSharp packages from nuget:
  
  <pre>
  Install-Package BioFSharp
  paket add BioFSharp
  </pre>
  
  All associated packages can be found [here](https://www.nuget.org/profiles/CSBiology)
  
  **Prerelease packages from the nuget branch:**
  
  Unstable/Experimental packages only.
  
  If you are using paket, add the following line to you `paket.dependencies` file:
  
  `git https://github.com/CSBiology/BioFSharp.git nuget Packages: /`
  
  you can then access the individual packages:
  
  `nuget BioFSharp`
  
  `nuget BioFSharp.BioContainers`
  
  `nuget BioFSharp.IO`
  
  `nuget BioFSharp.Stats`
  
  `nuget BioFSharp.ML`
  
  `nuget BioFSharp.BioDB`
  
  `nuget BioFSharp.Vis`
  
  
  **Build the binaries yourself:**
  
  **Windows**:
  
  - Install [.Net Core SDK](https://www.microsoft.com/net/download) 3.0 +
  - go to the project folder
  - `.\build.cmd`
  
  **Linux(using Mono)**:
  
  - BioDB is excluded from this build.
  
  - Install [.Net Core SDK](https://www.microsoft.com/net/download/linux-package-manager/ubuntu14-04/sdk-current)
  - go to the project folder
  - ./build.sh -t monoBuildChainLocal
  
  **Linux(Dotnet Core only)**:
  
  - this does only build projects targeting netstandard2.0 (Core, BioContainers, IO, Stats, ML)
  
  - Install [.Net Core SDK](https://www.microsoft.com/net/download/linux-package-manager/ubuntu14-04/sdk-current)
  - go to the project folder
  - ./build.sh -t dotnetBuildChainLocal

  ## Example
  
  The following example shows how easy it is to start working with sequences:
  
negative.code: // Create a nucleotide sequence 
  let nucleotideSequence = "ATGC" |> BioSeq.ofNucleotideString
  (***include-value:nucleotideSequence***)
