Step-by-step, task-oriented guides — do this, in this order, to get this result.
A complete walkthrough installing a C compiler and assembler on FreeDOS and building your first program — for anyone wanting to write software for DOS rather than just run it.

A complete walkthrough customizing Windows Terminal's settings.json and your PowerShell profile script — so your preferred shell, prompt, and startup behavior are there every time you open a terminal.
A complete walkthrough enabling Remote Desktop the right way — Network Level Authentication, a non-default port, and firewall scoping — rather than exposing RDP openly to the internet.
