# Add Variables to Steps

When using linked files (like your Attributes or regulatory databases), Protege AI automatically creates variables you can insert into policy steps for dynamic, context-aware reviews.

These variables can be used in multiple fields within a step, including:

* Explanation
* Prompt
* Keywords

#### To Add a Variable:

1. In the step editor, place your cursor in the field where you’d like to insert the variable (e.g., Explanation).

1. Press the $ key to open the list of available variables.
2. Select the appropriate variable from the dropdown list — this variable pulls matching data from the linked file.
3. Once inserted correctly, the variable name will turn green, indicating it’s properly connected.
