+# WebAssembly Proposals Support
+
+The following table summarizes Wasmtime's support for WebAssembly proposals as
+well as the command line flag and [`wasmtime::Config`][config] method you can
+use to enable or disable support for a proposal.
+
+If a proposal is not listed, then it is not supported by Wasmtime.
+
+Wasmtime will never enable a proposal by default unless it has reached phase 4
+of [the WebAssembly standardizations process][phases] and its implementation in
+Wasmtime has been [thoroughly
+vetted](./contributing-supporting-new-wasm-proposals.html).
+
+| WebAssembly Proposal                        | Supported in Wasmtime?           | Command Line Flag      | [`Config`][config] Method |
+|---------------------------------------------|----------------------------------|------------------------|---------------------------|
