-> Template to create conversational bots in Java using Microsoft Bot Framework.
+# generator-botbuilder-java
+
+Yeoman generator for [Bot Framework v4](https://dev.botframework.com).  Will let you quickly set up a conversational AI bot
+using core AI capabilities.
+
+## About
+
+`generator-botbuilder-java` will help you build new conversational AI bots using the [Bot Framework v4](https://dev.botframework.com).
+
+## Templates
+
+The generator supports three different template options.  The table below can help guide which template is right for you.
+
+|  Template  |  Description  |
+| ---------- |  ---------  |
+| Echo Bot | A good template if you want a little more than "Hello World!", but not much more.  This template handles the very basics of sending messages to a bot, and having the bot process the messages by repeating them back to the user.  This template produces a bot that simply "echoes" back to the user anything the user says to the bot. |
+| Empty Bot | A good template if you are familiar with Bot Framework v4, and simply want a basic skeleton project.  Also a good option if you want to take sample code from the documentation and paste it into a minimal bot in order to learn. |
+
+### How to Choose a Template
+
+| Template | When This Template is a Good Choice |
+| -------- | -------- |
+| Echo Bot  | You are new to Bot Framework v4 and want a working bot with minimal features. |
+| Empty Bot  | You are a seasoned Bot Framework v4 developer.  You've built bots before, and want the minimum skeleton of a bot. |
+
+### Template Overview
+
+#### Echo Bot Template
+
+The Echo Bot template is slightly more than the a classic "Hello World!" example, but not by much.  This template shows the basic structure of a bot, how a bot recieves messages from a user, and how a bot sends messages to a user.  The bot will "echo" back to the user, what the user says to the bot.  It is a good choice for first time, new to Bot Framework v4 developers.
+
+#### Empty Bot Template
+
+The Empty Bot template is the minimal skeleton code for a bot.  It provides a stub `onTurn` handler but does not perform any actions.  If you are experienced writing bots with Bot Framework v4 and want the minimum scaffolding, the Empty template is for you.
 
 ## Installation
 
-First, install [Yeoman](http://yeoman.io) and generator-botbuilder-java using [npm](https://www.npmjs.com/) (we assume you have pre-installed [node.js](https://nodejs.org/)).
+1. Install [Yeoman](http://yeoman.io) using [npm](https://www.npmjs.com) (we assume you have pre-installed [node.js](https://nodejs.org/)).
+
+    ```bash
+    # Make sure both are installed globally
+    npm install -g yo
+    ```
+
+2. Install generator-botbuilder-java by typing the following in your console:
+
+    ```bash
+    # Make sure both are installed globally
+    npm install -g generator-botbuilder-java
+    ```
+
+3. Verify that Yeoman and generator-botbuilder-java have been installed correctly by typing the following into your console:
+
+    ```bash
+    yo botbuilder-java --help
+    ```
+
+## Usage
+
+### Creating a New Bot Project
+
+When the generator is launched, it will prompt for the information required to create a new bot.
 
 ```bash
-npm install -g yo
-npm install -g generator-botbuilder-java
+# Run the generator in interactive mode
+yo botbuilder-java
 ```
 
-Then generate your new project:
+### Generator Command Line Options
+
+The generator supports a number of command line options that can be used to change the generator's default options or to pre-seed a prompt.
+
+| Command line Option  | Description |
+| ------------------- | ----------- |
+| --help, -h        | List help text for all supported command-line options |
+| --botName, -N     | The name given to the bot project |
+| --packageName, -P | The Java package name to use for the bot |
+| --template, -T    | The template used to generate the project.  Options are `empty`, or `echo`.  See [https://aka.ms/botbuilder-generator](https://aka.ms/botbuilder-generator) for additional information regarding the different template option and their functional differences. |
+| --noprompt        | The generator will not prompt for confirmation before creating a new bot.  Any requirement options not passed on the command line will use a reasonable default value.  This option is intended to enable automated bot generation for testing purposes. |
+
+#### Example Using Command Line Options
+
+This example shows how to pass command line options to the generator, setting the default language to TypeScript and the default template to Core.
 
 ```bash
-yo botbuilder-java
+# Run the generator defaulting the pacakge name and the template
+yo botbuilder-java --P "com.mycompany.bot" --T "echo"
 ```
 
-## Getting To Know Yeoman
+### Generating a Bot Using --noprompt
 
- * Yeoman has a heart of gold.
- * Yeoman is a person with feelings and opinions, but is very easy to work with.
- * Yeoman can be too opinionated at times but is easily convinced not to be.
- * Feel free to [learn more about Yeoman](http://yeoman.io/).
+The generator can be run in `--noprompt` mode, which can be used for automated bot creation.  When run in `--noprompt` mode, the generator can be configured using command line options as documented above.  If a command line option is ommitted a reasonable default will be used.  In addition, passing the `--noprompt` option will cause the generator to create a new bot project without prompting for confirmation before generating the bot.

+| Command line Option  | Default Value |
+| ------------------- | ----------- |
+| --botname, -N     | `echo` |
+| --packageName, -p | `echo` |
+| --template, -T    | `echo` |
+
+#### Examples Using --noprompt
+
+This example shows how to run the generator in --noprompt mode, setting all required options on the command line.
+
+```bash
+# Run the generator, setting all command line options
+yo botbuilder-java --noprompt -N "MyEchoBot" -P "com.mycompany.bot.echo" -T "echo"
+```
+
+This example shows how to run the generator in --noprompt mode, using all the default command line options.  The generator will create a bot project using all the default values specified in the **Default Options** table above.
+
+```bash
+# Run the generator using all default options
+yo botbuilder-java --noprompt
+```
