Currently the PC is linux, ubuntu CLI.
My experience with linux is newbie level, about 3 months in.
Can I ask for some newbie help with regards to mining in a stratum pool?
#1: What is stratum?
#2: Which client should I use to mine for different algorithms? What is the best client to use?
#3: How do I install a project from github?
Thank you!
For number three you need a github account - then you can "clone" the project to your own account and that creates a copy.
But you're only copying the raw code, not an actual program.
To actually install something depends on what you're cloning - you'll need a compiler to convert the code into a program, or some code you can run through terminal if you have the right software installed.
