Back already? No matter. Lay out your arms.

# see example ansible/inventory.yaml
ansible-playbook -i <inventory-file> ansible/playbook.yaml [--connection local] [--ask-become-pass]

The org-roam setup is outlined in the official docs. This worked for me: install msys2 and run:

pacman -Syu
# new tty
pacman -Su
pacman -S --needed base-devel mingw-w64-x86_64-toolchain
pacman -S gcc

Then add <msys2 install dir>/usr/bin to the windows %PATH% (Win+R systempropertiesadvanced - Environment Variables - System Variables)

GPG Keys: Problems with gpg keys and elpa if msys2 is installed: gpg --receive-keys 066DAFCB81E42C40 (do not set --homedir to the .emacs.d/elpa/gnupg thing as emacs is confused with the paths; the keys are installed to the msys2 home directory). In .emacs add '(package-gnupghome-dir nil) to use the default dir.
