+## API
+
+### WasmModule
+
+The constructor is going to return an instance of *WasmModule* which is an extension of the original WasmModule returned by the underlying <a href="https://www.npmjs.com/package/wabt">wabt</a> package.
+
+Additional helper methods:
+
+ #### *readString*(index: `number`, length?: `number`): `string`
+ Returns a string, provided an index, which should be a pointer in the module memory. 
+ #### *createString*(string: `string`, memoryLocation: `number`): `number`
+ Creates a string in the module memory and returns a pointer to it.
