+# VST 3 Host Checker
+
+## Introduction
+
+The VST 3 Host Checker plug-in can test a VST 3 host application. It tracks all incoming function calls, monitors calling sequences and performs various other tests.
+
+> See also: [Online Documentation](https://steinbergmedia.github.io/vst3_dev_portal/pages/What+is+the+VST+3+SDK/Plug-in+Examples.html?highlight=host%20checker#hostchecker).
+
+## Getting Started
+
+This plug-in is part of the VST 3 SDK package. It is created with the VST 3 SDK root project.
+
+> See the top-level README of the VST 3 SDK: https://github.com/steinbergmedia/vst3sdk.git
+
+## Getting Help
+
+* Read through the SDK documentation on the **[VST 3 Developer Portal](https://steinbergmedia.github.io/vst3_dev_portal/pages/index.html)**
+* Ask some real people in the official **[VST 3 Developer Forum](https://forums.steinberg.net/c/developer/103)**
