+# Z3 NuGet packaging
+
+## Creation
+
+ 1. After tagging a commit for release, sign Microsoft.Z3.dll and libz3.dll (both x86 and x64 versions) with Microsoft's Authenticode certificate
+ 2. Test the signed DLLs with the `Get-AuthenticodeSignature` PowerShell commandlet
+ 3. Create the following directory structure for the x64 package (for x86, substitute the "x64" strings for "x86" and use x86 DLLs):
+ ```
+ +-- Microsoft.Z3.x64
+ |   +-- Microsoft.Z3.x64.nuspec
+ |   +-- lib
+ |       +-- net40
+ |           +-- Microsoft.Z3.dll
+ |   +-- build
+ |       +-- Microsoft.Z3.x64.targets
+ |       +-- libz3.dll
+ ```
+ 4. Open the nuspec file and fill in the appropriate macro values (note that for all URLs, preserve link integrity by linking to a specific commit):
+    * $(releaseVersion) - the Z3 version being released in this package
+    * $(iconUrlFromReleaseCommit) - URL for the Z3 icon file
+    * $(licenseUrlFromReleaseCommit) - URL for the Z3 repo license
+    * $(releaseCommitHash) - hash of the release commit
+ 5. Run `nuget pack Microsoft.Z3.x64\Microsoft.Z3.x64.nuspec`
+ 6. Test the resulting nupkg file (described below) then submit the package for signing before uploading to NuGet.org
+
+## Testing
+
+ 1. Create a directory on your machine at C:\nuget-test-source
+ 2. Put the Microsoft.Z3.x64.nupkg file in the directory
+ 3. Open Visual Studio 2017, create a new C# project, then right click the project and click "Manage NuGet packages"
+ 4. Add a new package source - your C:\nuget-test-source directory
+ 5. Find the Microsoft.Z3.x64 package, ensuring in preview window that icon is present and all fields correct
+ 6. Install the Microsoft.Z3.x64 package, ensuring you are asked to accept the license
+ 7. Build your project. Check the output directory to ensure both Microsoft.Z3.dll and libz3.dll are present
+ 8. Import Microsoft.Z3 to your project then add a simple line of code like `using (var ctx = new Context()) { }`; build then run your project to ensure the assemblies load properly
