+# Packages
+
+A *package* groups related code — modules, classes, controls, and enumerations — under a single namespace, and is referenced from a project as a single dependency. See [Features → Packages](../../Features/Packages/) for how packages are built and distributed in general; the pages below document the *built-in* packages that ship with twinBASIC itself.
+
+## Default Packages
+
+These packages are included in every project by default.
+
+- [VB Package](VB/) -- standard controls (**CheckBox**, **CommandButton**, **TextBox**, …), forms, and the application-level singletons (**App**, **Screen**, **Clipboard**, **Printer**, …)
+- [VBA Package](VBA) -- the standard runtime library — **MsgBox**, **CStr**, **Mid**, **Format**, … grouped into modules, plus the **Collection** and **Err** intrinsics and twinBASIC's runtime expression engine
+- [VBRUN Package](VBRUN/) -- runtime-only types — ambient properties, asynchronous-read state, structured error context, the **PropertyBag**, the clipboard / drag-and-drop container, and the enumerations used by classic VB6 forms and controls
+
+## Built-In Packages
+
+These packages are built into twinBASIC and are always available, even offline. To use them, add them to Project → References (Ctrl-T) → Available Packages.
+
+- [Assert Package](Assert/) -- assertion functions for unit tests — three modules (**Exact**, **Strict**, **Permissive**) sharing the same fifteen-member API with different comparison strictness
+- [WebView2 Package](WebView2/) -- the **WebView2** control wrapping the Microsoft Edge runtime, plus its surrounding wrapper objects (request / response / headers / environment options) and the `wv2…` enumerations
