+# Build Instructions
+
+## Option 1: GitHub Actions (Easiest — No Setup Required)
+
+1. Create a GitHub account if you don't have one
+2. Create a new repo called `vulcast-vertical` (public is fine)
+3. Push this code to GitHub:
+
+```bash
+git remote add github https://github.com/YOUR_USERNAME/vulcast-vertical.git
+git push -u github main
+```
+
+4. Go to the repo → **Actions** tab → Click "Build Windows DLL" → **Run workflow**
+5. Wait ~5 minutes for the build to finish
+6. Click the workflow run → **Artifacts** section → Download `vulcast-vertical-windows-x64`
+7. Extract the zip — the `vulcast-vertical.dll` is inside
+
+## Option 2: Local Build (Requires Visual Studio 2022)
+
+See BUILD-WINDOWS.md for local build instructions.
