-# Getting Started with Create React App
+# Dialogflow Messenger
 
-This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+The Dialogflow Messenger integration provides a customizable chat dialog for your agent that can be embedded in your website. The chat dialog is implemented as a dialog window that can be opened and closed by your end-user. When opened, the chat dialog appears above your content in the lower right side of the screen.
 
-## Available Scripts
+## Run Messenger Locally
 
-In the project directory, you can run:
+In order to run the messenger locally, clone this repo, then run the app in development mode using npm run start.
+The <df-messenger /> tag can be customized, to change the agent or pass additional parameters, in public/index.html.
 
-### `npm start`
+IMPORTANT: Before running locally, add api-uri attribute to <df-messenger /> tag to connect Dialogflow Messenger to agent.
 
-Runs the app in the development mode.\
-Open [http://localhost:3000](http://localhost:3000) to view it in the browser.

-### `npm test`
+## Build Messenger Widget
 
-Launches the test runner in the interactive watch mode.\
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+The messenger can be compiled into a widget using the command npm run build:widget.
 
-### `npm run build`
-
-Builds the app for production to the `build` folder.\
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.\
-Your app is ready to be deployed!
-
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
-
-### `npm run eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
-
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
-
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
