+[Wasmtime][github] is a standalone runtime for WebAssembly, WASI, and the
+Component Model by the [Bytecode Alliance][BA].
+
+[WebAssembly] (abbreviated Wasm) is a binary instruction format that is designed
+to be a portable compilation target for programming languages. Wasm binaries
+typically have a `.wasm` file extension. In this documentation, we'll also use
+the textual representation of the binary files, which have a `.wat` file
+extension.
+
+[WASI] (the WebAssembly System Interface) defines interfaces that provide a
+secure and portable way to access several operating-system-like features such as
+filesystems, networking, clocks, and random numbers.
+
+[The Component Model] is a Wasm architecture that provides a binary format for
+portable, cross-language composition. More specifically, it supports the use of
+interfaces via which components can communicate with each other. WASI
+is defined in terms of component model interfaces.
+
+Wasmtime runs WebAssembly code [outside of the Web], and can be used both as a

+strives to be
+
+- **Fast**: Wasmtime is built on the optimizing [Cranelift] code generator.
+- **Secure**: Wasmtime's development is strongly focused on correctness and
+  security.
+- **Configurable**: Wasmtime uses sensible defaults, but can also be configured
+  to provide more fine-grained control over things like CPU and memory
+  consumption.
+- **Standards Compliant**: Wasmtime passes the official WebAssembly test suite
+  and the Wasmtime developers are intimately engaged with the WebAssembly
+  standards process.
