-The JavaScript version of [binaryen](https://github.com/WebAssembly/binaryen)'s C-API with TypeScript support.
+binaryen.js
+===========
+
+**binaryen.js** is a port of [Binaryen](https://github.com/WebAssembly/binaryen) to the Web, allowing you to generate WebAssembly using a JavaScript API.
+
+[![Build Status](https://travis-ci.org/dcodeIO/binaryen.js.svg?branch=master)](https://travis-ci.org/dcodeIO/binaryen.js)
+
+Usage
+-----
+
+```
+$> npm install binaryen
+```
+
+```js
+var binaryen = require("binaryen");
+
+var myModule = new binaryen.Module();
+myModule.addFunction("main", mod.addFunctionType("i", binaryen.i32, []), [], mod.return(mod.i32.const(0)));
+myModule.addExport("main", "main");
+
+var textData = myModule.emitText();
+var wasmData = myModule.emitBinary();
+...
+```
+
+The buildbot also publishes nightly versions once a day. The latest nightly can be installed through
+
+```
+$> npm install binaryen@nightly
+```
+
+or you can use one of the [previous versions](https://github.com/dcodeIO/binaryen.js/tags) instead if necessary.
+
+API
+---
+
+The API is documented in the rest of this document.
+
+### Types
+
+ * `binaryen.none`: The none type.
+ * `binaryen.i32`: The i32 type.
+ * `binaryen.i64`: The i64 type.
+ * `binaryen.f32`: The f32 type.
+ * `binaryen.f64`: The f64 type.
+
+### Modules
+
+ * `binaryen.Module()`: Constructor for a Binaryen WebAssembly module. You need to create one of these first.
+
+`Module` instances have the following properties.
+
+Module property operations:
+
+  * `addFunctionType(name, resultType, paramTypes)`: Add a function type to the module, with a specified name, result type, and param types.
+  * `getFunctionTypeBySignature(resultType, paramTypes)`: Gets an existing function type by its signature. Returns `0` if there is no such function type yet.
+  * `addFunction(name, functionType, varTypes, body)`: Add a function, with a name, a function type, an array of local types, and a body.
+  * `addImport(internalName, externalModuleName, externalBaseName, functionType)`: Add an import, with an internal name (used by other things in the module), an external module name (the module from which we import), an external base name (the name we import from that module), and a function type (for function imports).
+  * `removeImport(internalName)`: Removes an import by its internal name.
+  * `addExport(internalName, externalName)`: Add an export, with an internal name and an external name (the name the outside sees it exported as).
+  * `removeExport(externalName)`: Removes an export by its external name.
+  * `setFunctionTable(funcs)`: Sets the function table to a array of functions.
+  * `setMemory(initial, maximum, exportName, segments)`: Sets the memory to having an initial size, maximum size, optional export name, and array of data segments.
+  * `setStart(start)`: Sets the start function (called when the module is instantiated) to a specified function.
+
+Module operations:
+
+  * `emitBinary()`: Returns a binary for the module, which you can then compile and run in the browser.
+  * `emitText()`: Returns a text representation of the module, in s-expression format.
+  * `validate()`: Validates the module, checking it for correctness. Returns `1` if the module is valid, otherwise `0`.
+  * `optimize()`: Optimize the module.
+  * `autoDrop()`: Automatically inserts `drop` operations. This lets you not worry about dropping when creating your code.
+  * `interpret()`: Run the module in the Binaryen interpreter (creates the module, and calls the start method). Useful for debugging.
+  * `dispose()`: Cleans up the module. If the Binaryen object can be garbage-collected anyhow, you don't need to do this, but if it stays around - e.g. if you create multiple `Module`s over time - then you should call this once a `Module` is no longer needed. (As binaryen.js uses compiled C++ code, we can't just rely on normal garbage collection to clean things up internally.)

+(now done with `Module`s, returning to the `Binaryen` object)
+
+  * `Binaryen.readBinary(data)`: Reads a binary wasm module and returns a Binaryen `Module` object created from it.
+  * `Binaryen.parseText(text)`: Parses a module in text representation and returns a Binaryen `Module` object created from it.
+  * `Binaryen.emitText(expression)`: Returns a text representation of an individual expression, in s-expression format. Because Binaryen expression do not depend on their function or module, you can do this at any time.
+  * `setAPITracing(on)`: Sets whether API tracing is on. When on, this emits C API commands for everything you do. This can be very useful for filing bug reports.
+  * `Binaryen.Relooper()`: Constructor for a Binaryen Relooper instance. This lets you provide an arbitrary CFG, and the Relooper will structure it for WebAssembly.
+
+Relooper instances have the following methods:
+
+  * `addBlock(code)`: Adds a new block to the CFG, containing the provided code (expression) as its body.
+  * `addBranch(from, to, condition, code)`: Adds a branch from a block to another block, with a condition (or nothing, if this is the default branch to take from the origin - each block must have one such branch), and optional code to execute on the branch (useful for phis).
+  * `addBlockWithSwitch(code, condition)`: Adds a new block, which ends with a switch/br_table, with provided code and condition (that determines where we go in the switch).
+  * `addBranchForSwitch(from, to, indexes, code)`: Adds a branch from a block ending in a switch, to another block, using an array of indexes that determine where to go, and optional code to execute on the branch.
+  * `renderAndDispose(entry, labelHelper, module)`: Renders and cleans up the Relooper instance. Call this after you have created all the blocks and branches, giving it the entry block (where control flow begins), a label helper variable (an index of a local we can use, necessary for irreducible control flow), and the module. This returns an expression - normal WebAssembly code - that you can use normally anywhere.
