 Alternatively, most of the more developed forks (such as InvokeAI) come with their own user interfaces.
 
+To get up and running, one usually needs:
+- A GUI or CLI based installation on a supported platform (usually NVIDIA GPU but support for Apple Silicon, AMD GPUS and even CPU exists in some branches)
+- The weights (.ckpt files) for the model downloaded from Huggingface
+- Sufficent RAM/VRAM available on the system.
