1. Choose a historical location or site that has changed over time
2. Create a post by clicking the + button and searching for your location
3. In your post:
   • Add a historical image of your chosen location
   • Fill in when the historical image is from
   • Describe what has changed between then and now
   • Explain what this tells us about how the location has developed
