Could you please provide a step-by-step guide on how to install XCAD? I'm new to the world of cryptocurrency and I'm interested in learning how to get started with XCAD. I've tried searching online but I'm finding it difficult to find a clear and concise installation guide. Could you please break it down for me in simple, easy-to-follow steps? I'd appreciate it if you could also mention any system requirements or compatibility issues that I should be aware of before proceeding with the installation. Thank you in advance for your help.
