Save and publish a lesson
=========================

You can only publish an exploration that follows a clear logical path.
If you're having trouble publishing your lesson, there's likely an issue
with one or more cards.

To save and publish in the **Exploration Editor**:

1. Select **Save Draft** above the **Exploration Editor** navigation
   bar to ensure you publish the most up-to-date version.
2. Select **Publish** above the **Exploration Editor** navigation
   bar.
   * Add additional details about your exploration such as a goal, a category, tags, etc.
3. Select **Save Changes**.

Your lesson is now live on the Oppia platform. You can view or share the
exploration.

**Note:** Your exploration ID is the letters and numbers that appear
*after* “/explore/.”


.. _navigate_publishing_issues_ref:

Navigate publishing issues
============================

If the option to publish is greyed out, there is an unresolved structure
or logic issue. In the **Exploration Editor** panel, review each card's warning
icon. It will highlight issues like:

-  Isolated cards (cards not connected to the main path)
-  Interactions that loop indefinitely

Once you've resolved the lesson's functionality issues, the **Publish**
button turns green, indicating that you can now publish your
exploration.
