+
+It provides a function that takes two string arguments and returns a hash like this:
+
+``` javascript
+{
+  steps: 5,       // Levenstein demerau distance
+  relative: 0.7,  // steps / length of the longer string
+  similarity: 0.3 // 1 - relative
+}
+```
+
+## Install
+
+```sh
+npm install damerau-levenshtein
+```
+
+## Use with ES6 modules
+
+```js
+import * as levenshtein from 'damerau-levenshtein';
+
+const lev = levenshtein('hello world', 'Hello World!');
+// { steps: 4, relative: 0.3076923076923077, similarity: 0.6923076923076923 }
+```
+
+Please see [tests](./test/test.js) for more insights.
+
+## Use with TypeScript
+
+```ts
+import * as levenshtein from 'damerau-levenshtein';
+
+interface LevenshteinResponse {
+  steps: number;
+  relative: number;
+  similarity: number;
+}
+
+const lev: LevenshteinResponse = levenshtein('hello world', 'Hello World!');
+
+console.log(lev.steps);
+// 2
+console.log(lev.foo);
+// TypeScript Error: Property 'foo' does not exist on type 'LevenshteinResponse'.
+```
