First of all we need to set up Löve. Then we will dive right in to development and create a SHMUP and later a small rpg.
But first: What do we need to install?
Hint: This book covers the whole development process from begin to end. But if you want to find more learning resources on Löve wiki is a great place to start. You could for example read the Getting Started Guide. See also the Learning Lua section in the Appendix.
