A project’s type is determined by the template that was selected when creating the project. After a project is created, its type cannot be modified. - **Category**: Click **Edit**![Icon Description automatically generated](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Pencil%20icon_App%20Builder.png)to enter a category for the project. This field is open ended and can be used to classify Apps in any way that works best for users on your ThreatConnect instance. As you type, a list of existing categories that contain the entered characters will be displayed. Select an existing category by clicking on it, or enter a new category, and then click **Confirm**![](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Confirm%20icon_App%20Builder.png). - **Labels**: Click **Edit**![Icon Description automatically generated](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Pencil%20icon_App%20Builder.png)to enter labels for the project. Labels are keywords that are used to classify projects. For example, labels such as “In Design” and “QA” can be used to track the development or status of a project, and labels such as “Utility” and “Signatures” or the creator’s name or initials can be used to make filtering projects more manageable. Labels also function as searchable tags that enable an App to be returned in the search results when searching for Apps in the **Apps**pane of the **Playbook Designer**. For example, a search for “AMA” will return Apps with this label even when the names of the Apps do not contain “AMA.” As you type, a list of existing labels that contain the entered characters will be displayed. Select an existing label by clicking on it, or create a new label by clicking **Add**![Plus icon_Gray](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Plus%20icon_Gray.png). You can apply more than one label to a project. - **Python Version**: Select the Python® version for the App, which will be stored in the App’s **install.json**file. Available versions include 3.6 and 3.11. For new Apps, **3.11.0**will be selected by default; for existing Apps using Python 3.6 or that were cloned from an App using Python 3.6, **3.6**will be selected by default.ImportantOnly Apps using TcEx 4.0.*x* can use Python 3.11. Apps using a TcEx version older than 4.0.*x* must use Python 3.6. To determine an App's TcEx version, refer to the App's **requirements.txt** file located in the **[](https://knowledge.threatconnect.com/docs/contents-tab)**[](https://knowledge.threatconnect.com/docs/contents-tab)[**Contents**tab](https://knowledge.threatconnect.com/docs/contents-tab)[](https://knowledge.threatconnect.com/docs/contents-tab)**[](https://knowledge.threatconnect.com/docs/contents-tab)**.ImportantIf you change the Python version for an App, you are responsible for resolving any dependency issues and managing the version going forward. - **App Note**: Click **Edit**![Icon Description automatically generated](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Pencil%20icon_App%20Builder.png)to enter general information about the App and its parameters. The **App Note**will be displayed when a user clicks the **Display Documentation**![Playbooks_Display Documentation icon](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Playbooks_Display%20Documentation%20icon.png)icon in the **Edit App**pane of the [Playbook Designer](/v1/docs/the-playbook-designer) while configuring the App. See the [“Creating an App Note”](/docs/metadata-tab#creating-an-app-note) section for more information.
