+## Usage
+
+Add `wasm-encoder` to your `Cargo.toml`
+
+```sh
+$ cargo add wasm-encoder
+```
+
+And then you can encode WebAssembly binaries via:
+
+```rust
+use wasm_encoder::{
+ CodeSection, ExportKind, ExportSection, Function, FunctionSection, Instruction,
+ Module, TypeSection, ValType,
+};
+
+let mut module = Module::new();
+
+// Encode the type section.
+let mut types = TypeSection::new();
+let params = vec![ValType::I32, ValType::I32];
+let results = vec![ValType::I32];
+types.function(params, results);
+module.section(&types);
+
+// Encode the function section.
+let mut functions = FunctionSection::new();
+let type_index = 0;
+functions.function(type_index);
+module.section(&functions);
+
+// Encode the export section.
+let mut exports = ExportSection::new();
+exports.export("f", ExportKind::Func, 0);
+module.section(&exports);
+
+// Encode the code section.
+let mut codes = CodeSection::new();
+let locals = vec![];
+let mut f = Function::new(locals);
+f.instruction(&Instruction::LocalGet(0));
+f.instruction(&Instruction::LocalGet(1));
+f.instruction(&Instruction::I32Add);
+f.instruction(&Instruction::End);
+codes.function(&f);
+module.section(&codes);
+
+// Extract the encoded Wasm bytes for this module.
+let wasm_bytes = module.finish();
+
+// We generated a valid Wasm module!
+assert!(wasmparser::validate(&wasm_bytes).is_ok());
+```
