# Dataset Versions

Versions are point-in-time snapshots of the images and labels in your dataset. When you create a Version, you can apply preprocessing steps and augmentations to your dataset.

To train a model in Roboflow, you need to create a Dataset Version.

This section of our documentation walks through how to prepare to train a model. You will need to:

{% stepper %}
{% step %}
**Open the Versions page and create a new version**

Follow our guide to get to the [page that lets you create a dataset version](/datasets/dataset-versions/create-a-dataset-version.md).
{% endstep %}

{% step %}
**Choose preprocessing steps**

Select the [preprocessing steps](/datasets/dataset-versions/image-preprocessing.md) you need to train your model.
{% endstep %}

{% step %}
**Apply augmentations**

[Apply any augmentations to your dataset](/datasets/dataset-versions/image-augmentation.md). We have a guide that walks through which augmentations are appropriate for different use cases.
{% endstep %}

{% step %}
**Confirm your Version**

Your Version will be created and will now be available for use in training models.
{% endstep %}

{% step %}
**Train a model**

Follow our [model training documentation](/train/train.md) to configure your training job.

You can also [export a dataset version](/datasets/dataset-versions/exporting-data.md).
{% endstep %}
{% endstepper %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.roboflow.com/datasets/dataset-versions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
