A tour of Evennia and how to use the tools, including an introduction to Python.
- Part 2: [What We Want](../Part2/Beginner-Tutorial-Part2-Overview.md)
Planning our tutorial game and what to consider when planning your own.
- Part 3: [How We Get There](../Part3/Beginner-Tutorial-Part3-Overview.md)
Getting down to the meat of extending Evennia to make your game.
- *Part 4: [Using What We Created](./Beginner-Tutorial-Part4-Overview.md)*
Building a tech-demo and world content to go with our code.
- Part 5: [Showing the World](../Part5/Beginner-Tutorial-Part5-Overview.md)
Taking our new game online and letting players try it out.
```
We now have the code underpinnings of everything we need. We have also tested the various components and has a simple tech-demo to show it all works together. But there is no real coherence to it at this point - we need to actually make a world. In part four we will expand our tech demo into a more full-fledged (if small) game by use of batchcommand and batchcode processors.
