+# Spell Check Middleware
+
+The Spell Check Middleware offers Bot Framework middleware components for the Cognitive Services Bing Spell Check API. You will need an Azure account, as well as a Cognitive Services resource created on Azure. Take a look at the [Bing Spell Check API documentation](https://azure.microsoft.com/en-us/services/cognitive-services/spell-check/) for details.
+
+## Installing
+
+    npm install @botbuildercommunity/spell-check-middleware --save
+
+## Usage
+
+All middleware is created and use in the same way. For example, for spell check, import the `SpellCheck` class from the package, and add it to your bot adapter:
+
+```typescript
+import { SpellCheck } from '@botbuildercommunity/spell-check-middleware';
+
+adapter.use(new SpellCheck(YOUR_BING_SPELL_CHECK_KEY));
+```
+
+When used, the `turnState` on the `TurnContext` will have a property named `suggestion` which is the actual suggestion. Furthermore `turnState` will have a property `token` which is the phrase which has been classified by the service to be replaced by the suggestion. A full example can be seen in the [`bot.js`](test/bot.js) bot test file.
+
+Supported middleware classes include:
+
+* `SpellCheck`
+
+Each class takes the one required parameter like in the example usage above.
+
+In each case, properties are added to the `turnState` of the `TurnContext` You can retrieve them in your bot via:
+
+* `context.turnState.get("token")` //This is the token which you could replace by `suggestion`
+* `context.turnState.get("suggestion")` //This is the suggestion which the `token` could be replaced with
