# Getting Started with Worldbuilding

Worldbuilding is the process of constructing an imaginary world, sometimes associated with a whole fictional universe.

## Key Elements

1. **Geography**: Define the physical layout of your world
2. **History**: Create a timeline of major events
3. **Culture**: Develop societies and their customs
4. **Magic/Technology**: Establish the rules of your world

Start small and expand gradually. You don't need to build everything at once!
