There are several ways to download and install Wyam depending on which platform you're using and how much automation and control you want. Note that Wyam currently runs on the .NET Framework 4.6.2 and is therefore Windows-only. It also does not support Mono at this time. Plans to port to .NET Core and enable cross-platform execution are already in the works.

Zip File

To download Wyam as a zip file, visit the Releases page and download the most recent archive. Then unzip it into a folder of your choice. That's it. The zip archive contains an executable wyam.exe as well as all the required libraries. You may also want to add the folder where you unzipped Wyam to your path, but that step is optional.

Note that you may also need to right-click the zip file after download and select "Unblock" in the Security section of the properties dialog, otherwise you could get strange errors when using the application.

Windows Installer

To download Wyam as an installable Windows application, visit the Releases page and download the most recent Setup.exe. That will install Wyam along with a utility application called Wyam.Windows. It will also add Wyam to the Programs and Features control panel and create a Wyam.Windows Start Menu group. It also creates a shortcut that opens a command prompt with the current version of Wyam in the path.

Note that when you install Wyam from the installer, it is placed on your system at %LocalAppData%\Wyam (on most systems this is located at C:\Users\username\AppData\Local\Wyam).

The Wyam.Windows application contains some helpful commands to configure and control your environment:

usage:  <command> [<args>]

    update         Update to the latest version.
    add-path       Add the installation path to the PATH system
                   environment variable.
    remove-path    Remove the installation path from the PATH system
                   environment variable.

Of particular note, run wyam.windows.cmd update to perform an update of Wyam to the latest version. Note that this utility application is different from the main wyam.exe that you should use to actually run Wyam.

Tools Package

One of the NuGet packages provided by Wyam is a "tools package". This means that it includes the wyam executable as well as all other required libraries in a special "tools" subfolder that gets unpacked when the package is downloaded. This is helpful in cases where you want to obtain the Wyam command line application from NuGet (as opposed to downloading it directly). For example, a tools package allows you to easily use Wyam in Cake build scripts.

For more information about how tools packages work, see the excellent blog post How to use a tool installed by Nuget in your build scripts.

Chocolatey

Wyam will be added to Chocolatey soon, see issue #95 for more details. In the meantime, you can use the following command to install Wyam as a tool from Chocolatey:

choco install Wyam -s https://www.nuget.org/api/v2/

Libraries

If you're developing addins or you want to embed Wyam in your own applications you can use Wyam.Common for developing addins and Wyam.Core for embedding the engine. These are both available as packages on NuGet. If you're embedding Wyam and your configuration requires other libraries (such as modules), you may also have to search NuGet for related Wyam libraries and add those too.

Development Builds

You can also get the most recent builds at the MyGet feed:

NuGet V3 clients (VS 2015, Wyam): https://www.myget.org/F/wyam/api/v3/index.json

NuGet V2 clients (VS 2013, Cake): https://www.myget.org/F/wyam/api/v2

To use the development feed inside a Wyam configuration file for a particular module, specify it like this:

#n Wyam.Markdown -s https://www.myget.org/F/wyam/api/v3/index.json -l
