# Setup DB Action

A reusable Gitea Action that sets up the Trivy vulnerability database, restoring from cache if available.

**Note:** This action only sets up the database. Trivy itself must be installed separately (e.g., using the `setup-trivy` action).

## Usage

### Basic Usage

```yaml
- name: Setup DB
