+## NuGet Build
+
+To build the NuGet package run the following command to build a debug flavor, preview package into the **artifacts** folder.
+
+    dotnet pack
+
+When building the officially released version run: (see Note below about current `git` repository)
+
+    dotnet pack -c Release -p:VersionSuffix=''
+
+Which will build the final/stable package.
+
+NOTE: When building the officially released version, ensure that your `git` repository has the `origin` remote set to `https://github.com/apache/arrow.git`, which will ensure Source Link is set correctly. See https://github.com/dotnet/sourcelink/blob/master/docs/README.md for more information.
+
+There are two output artifacts:
+1. `Apache.Arrow.<version>.nupkg` - this contains the exectuable assemblies
+2. `Apache.Arrow.<version>.snupkg` - this contains the debug symbols files
+
+Both of these artifacts can then be uploaded to https://www.nuget.org/packages/manage/upload.
+
+## Docker Build
 
 Build from the Apache Arrow project root.
 
     docker build -f csharp/build/docker/Dockerfile .
 
-# Testing
+## Testing
