-Uno Check tool
+**Uno.Check** is a cross-platform, command-line .NET tool that validates and configures your development environment in a single step.
+Once installed as a global tool, it runs a series of “checkups”, reports any missing or misconfigured components, and can apply automatic fixes.
+Designed to simplify setup and ensures you have everything you need to build and debug Uno apps with confidence.

+
+### Build & install a local version
+
+We include a helper script to pack and install your locally built `uno.check` as a global tool, so you can test changes immediately on your machine:
+
+```powershell
+# From the repo root:
+./pack-and-install.ps1
+```

+.SYNOPSIS
+    Pack a .NET solution (or current folder), generate a LocalOnly.NuGet.Config
+    inside the feed directory (so it won't affect the solution), and install
+    (or reinstall) the Uno.Check global tool from that feed.
+
+.PARAMETER Solution
+    Optional path to a .sln file or project folder.
+    If omitted or empty, `dotnet pack` will run on the current directory.
+
+.PARAMETER LocalFeed
+    Optional directory to emit nupkg files into.
+    If omitted or empty, defaults to `LocalFeed` in the script folder.
+
+.EXAMPLE
+    Packs the solution from the current directory and places all nupkg files in ./LocalFeed
+	Removes any installed Uno.Check versions and installs locally-built version instead.
+    ./pack-and-install.ps1
+
+.EXAMPLE
+    # Packs path/to/MySolution.sln into ./MyFeed folder. 
+	Removes any installed Uno.Check versions and installs locally-built version instead.
