+# `Geekeey.Extensions.Process`
+
+## Features
+
+## Getting Started
+
+
+### Install the NuGet package:
+
+```
+dotnet add package Geekeey.Extensions.Process
+```
+
+You may need to add our NuGet Feed to your `nuget.config` this can be done by adding the following lines
+
+```xml
+<packageSources>
+	<add key="geekeey" value="https://git.geekeey.de/api/packages/geekeey/nuget/index.json" />
+</packageSources>
+```
+
+### Configure
+
+The package adds a global using for the functions in the `Prelude` class when the `ImplicitUsings` is enabled in
+the `.csproj` file. This global using is recommended but can also be removed, by removing
+the `Geekeey.Extensions.Process.Prelude` value from the item group `<Usings>`. For more information about that see
+the `Project.props` file inside the project tree.
+
+### Usage
+
+```csharp
+public static Task<int> Main()
+{
+	var stdout = new StringBuilder();
+	var cmd = Run("git").WithArguments(["config", "--get", "user.name"]) | stdout;
+	await cmd.ExecuteAsync();
+	Console.WriteLine(stdout.ToString());
+	return 0;
+}
+```
+
+```csharp
+public static Task<int> Main()
+{
+	var cmd = Run("cat").WithArguments(["file.txt"]) | Run("wc");
+	await cmd.ExecuteAsync();
+	Console.WriteLine(stdout.ToString());
+}
+```
