# Launch a diary study

When you're ready to open your study to participants, you'll launch it from the builder.

**To launch your diary study:**

{% stepper %}
{% step %}
Open your study in the builder.
{% endstep %}

{% step %}
Click **Launch study** in the bottom right corner. A study summary modal is displayed.

<div align="left"><figure><img src="https://3976082747-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIKfn7RcT4CW9XaIbqAdd%2Fuploads%2FARL4LPPPyudEUnvgtf0p%2FLaunch_diary.jpg?alt=media&amp;token=0575b2aa-9245-43ef-9b29-d18ab41709f3" alt="" width="563"><figcaption></figcaption></figure></div>

{% hint style="info" %}
**Note:** If you still have unmet requirements, you'll see a **Before you launch** button with a count instead. Open it to see what needs your attention, and resolve each item to launch your study.
{% endhint %}
{% endstep %}

{% step %}
Confirm the displayed summary of your study. If anything looks off, click **Cancel** and make the necessary adjustments to your study.
{% endstep %}

{% step %}
Click **Launch study**.

{% endstep %}
{% endstepper %}

Now, your study is launched—congrats! You're one step closer to getting valuable insights. For information on what happens next, see the section below.

## What happens when I launch my study?

Launching your study results in slightly different behavior depending on how you recruit participants:

* **Adding participants from a screener or previous study:** Participants you've added from a Dscout screener or another Dscout study automatically receive an email inviting them to your study.
* **Inviting your own participants by email:** Participants you've added manually (by name and email) automatically receive an email inviting them to your study.
* **Using a study webpage:** If you're bringing your own participants using a study webpage, launching your study activates the webpage. You can then share the webpage link with anyone you want to invite, and they'll be able to sign up for your study. For more information, see [Diary webpages](/diary-studies/what-are-diary-studies-in-dscout/diary-webpages.md).

Need to invite more participants after launch? For more information, see [Invite participants to a diary study](/diary-studies/manage-a-diary-study/invite-participants-to-a-diary-study.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://help.dscout.com/diary-studies/manage-a-diary-study/launch-a-diary-study.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.
