## Create a new project

A single command sets up a complete project for you with some example training data.

```
rasa init
```

This creates the following files:

```
.
├── __init__.py
├── actions.py
├── config.yml
├── credentials.yml
├── data
│   ├── nlu.md
│   └── stories.md
├── domain.yml
├── endpoints.yml
└── models
    └── <timestamp>.tar.gz
```

## Train a Model

The main command is:

```
rasa train
```

This command trains a Rasa model that combines a Rasa NLU and a Rasa Core model. If you only want to train an NLU or a Core model, you can run `rasa train nlu` or `rasa train core`.

## Interactive Learning

To start an interactive learning session with your assistant, run:

```
rasa interactive
```

## Talk to your Assistant

To start a chat session with your assistant on the command line, run:

```
rasa shell
```

## Start a Server

To start a server running your Rasa model, run:

```
rasa run
```

## Start an Action Server

To run your action server run:

```
rasa run actions
```

## Visualize your Stories

To open a browser tab with a graph showing your stories:

```
rasa visualize
```

## Evaluating a Model on Test Data

To evaluate your model on test data, run:

```
rasa test
```

## Create a Train-Test Split

To create a split of your NLU data, run:

```
rasa data split nlu
```

## Convert Data Between Markdown and JSON

To convert NLU data from various formats to JSON or Markdown, run:

```
rasa data convert nlu
```

## Export Conversations to an Event Broker

To export events from a tracker store using an event broker, run:
