+## Changes in v4
+  - The parameter `options.name` has been deprecated. 
+  - The env parameter `ILP_CREDENTIALS` has been deprecated in favour of `ILP_OPTIONS`.
+  - The module now includes type definitions for `Plugin` and related types and therefore exports both the type definitions and the `createPlugin` and `isPlugin` functions.

+## Examples

-First, the script checks whether `ILP_CREDENTIALS` is defined in the environment.
-`ILP_CREDENTIALS` must contain a JSON object with the options passed into the
-constructor of `ilp-plugin-btp` or the module name in `ILP_PLUGIN`.
+TypeScript:
+```typescript
+import createPlugin, { DataHandler } from '..'
+const plugin = createPlugin()
+const echo: DataHandler = (data: Buffer) => {
+  return Promise.resolve(data)
+}
+
+async function run () {
+  plugin.registerDataHandler(echo)
+  await plugin.connect()
+  await plugin.sendData(/* ... */)
+  process.exit(0)
+}
+
+run()
+```
+
+If no parameters are provided it will attempt to find the config in environment variables. If these are not found it will load a plugin that attempts to connect to a local moneyd instance on port 7768.
+
+The Environment variables that can be set are:
+
+`ILP_PLUGIN` : The name/path of the plugin module
+`ILP_PLUGIN_OPTIONS` : The options passed to the constructor, serialized as a JSON object.
 
-By default, a random secret will be generated and the plugin will connect to
-`btp+ws://localhost:7768`.
+The options object passed is a subset of the account configuration object proveded to `ilp-connector`.
