Normally, we put descriptions directly into the custom field's description textbox, as demonstrated. You can also put your descriptions into the field configuration settings, such as hiding a field. Doing so offers the following advantages:

• You can have different help text for different project/issue type contexts.
• You can set help text for fields that are not custom fields, such as Summary and Description.

Proceed with the following steps to set field descriptions in the field configuration:

1. Navigate to Administration > Issues > Field Configurations.
2. Click on the Configure link for the field configuration used by the project and issue type.
3. Click on the Edit link for the field.
4. Enter the HTML snippets into the Description field, and click on Update.
