Walkthroughs & Lab Wiki
The lab wiki contains hints and walkthroughs for a majority of lab machines. In addition there are also video walkthroughs for the bigger labs and you can reach out on Discord to either @xct or the community for additional help & guidance.
Besides direct help you can also find techniques & tools in the wiki that can help you on your learning path. This includes for example custom loaders & various commands & techniques used throughout the lab.
