+Debian setup script
+
+This repository contains a simple idempotent-ish script to provision a Debian-based machine after a rebuild.
+
+Files
+- setup-debian.sh: main script to run (creates/updates ~/.bashrc entries)
+
+Usage
+1. Make the script executable and run it as your user (it will use sudo when needed):
+
+```bash
+chmod +x ~/setup-debian.sh
+~/setup-debian.sh
+```
+
+Optional: set your global Git identity during setup:
+
+```bash
+GIT_USER_NAME="Your Name" GIT_USER_EMAIL="you@example.com" ~/setup-debian.sh
+```
+
+or run with sudo:
+
+```bash
+sudo bash ~/setup-debian.sh
+```
+
+What the script does
+- Updates apt and installs requested packages (curl, net-tools, ncdu, tmux, htop, nala, neofetch, nfs-common, git, neovim, etc.)
+- Installs `snapd` and installs Bitwarden via snap
+- Attempts to detect a unix socket (ssh/bitwarden) and export `SSH_AUTH_SOCK` to `~/.bashrc`
+- Installs VS Code via snap
+- Installs latest `kubectl` binary and enables bash completion + aliases (`k`)
+- Adds a `fgk` alias for `flux get kustomizations all`
+- Adds arrow-key history search (type prefix then Up/Down)
+
+Notes
+- The script attempts to detect a Bitwarden SSH agent socket but may not find it automatically depending on how Bitwarden exposes it; if needed, manually set `SSH_AUTH_SOCK` in your shell to the socket path.
+- `flux` must be installed separately if you need `fgk` to work.
