+# Shared Dotfiles
+
+System-wide dotfiles for an Arch Linux + Hyprland desktop, stored in a shared
+folder so every user on the machine can read and edit them, and symlink them
+into their own `~/.config`.
+
+Included configs:
+
+| Folder       | Application | Links to                    |
+| ------------ | ----------- | --------------------------- |
+| `hypr`       | Hyprland    | `~/.config/hypr`            |
+| `nvim`       | Neovim (LazyVim) | `~/.config/nvim`       |
+| `quickshell` | Quickshell  | `~/.config/quickshell`      |
+
+---
+
+## 1. Shared folder setup (admin, one time)
+
+The repo lives in `/opt/shared-configs` and is owned by a common group
+(`sharedconfig`) so any member can edit the files.
+
+```bash
+# Create the shared group
+sudo groupadd sharedconfig
+
+# Add each user who should be able to edit the configs
+sudo gpasswd -a <username> sharedconfig   # repeat per user
+
+# Clone (or move) the repo into the shared location
+sudo git clone git@github.com:SamriddhVerma/dotfiles.git /opt/shared-configs
+
+# Give the group ownership of everything
+sudo chgrp -R sharedconfig /opt/shared-configs
+
+# Make it group-writable, and set the setgid bit on all directories so new
+# files/dirs automatically inherit the sharedconfig group
+sudo chmod -R g+rwX /opt/shared-configs
+sudo find /opt/shared-configs -type d -exec chmod g+s {} +
+```
+
+> Group membership only takes effect on a new login — log out/in (or run
+> `newgrp sharedconfig`) after being added.
+
+Optional: set a default ACL so future files stay group-writable regardless of
+each user's umask:
+
+```bash
+sudo setfacl -R -d -m g:sharedconfig:rwX /opt/shared-configs
+```
+
+---
+
+## 2. Install the required packages
+
+All configs target Arch Linux, installed with `pacman` (AUR helper such as
+`yay`/`paru` needed for the AUR items).
+
+```bash
+# Core desktop (Hyprland session)
+sudo pacman -S --needed \
+  hyprland kitty thunar fuzzel \
+  grim slurp wl-clipboard \
+  brightnessctl playerctl \
+  pipewire pipewire-pulse wireplumber \
+  networkmanager upower bluez bluez-utils
+
+# Neovim (LazyVim) + common tooling
+sudo pacman -S --needed neovim git ripgrep fd
+
+# AUR packages
+yay -S quickshell mpvpaper
+```
+
+Optional, only if you run a hybrid NVIDIA setup (the wallpaper autostart uses
+`prime-run`):
+
+```bash
+sudo pacman -S --needed nvidia-prime
+```
+
+Enable the required services:
+
+```bash
+sudo systemctl enable --now NetworkManager bluetooth
+```
+
+---
+
+## 3. Symlink the configs into your `~/.config`
+
+Point your personal config directories at the shared folder. Existing configs
+are backed up first.
+
+```bash
+SRC=/opt/shared-configs
+mkdir -p ~/.config
+
+for cfg in hypr nvim quickshell; do
+  # back up an existing real config if present
+  [ -e ~/.config/$cfg ] && [ ! -L ~/.config/$cfg ] && \
+    mv ~/.config/$cfg ~/.config/$cfg.bak
+
+  ln -sfn "$SRC/$cfg" ~/.config/$cfg
+done
+```
+
+Verify:
+
+```bash
+ls -l ~/.config/hypr ~/.config/nvim ~/.config/quickshell
+```
+
+Because the targets are symlinks into the shared repo, any edit you make (as a
+`sharedconfig` member) is shared with every other user, and can be committed
+back with `git`.
+
+---
+
+## Notes
+
+- **Hyprland** uses the Lua config (`hypr/hyprland.lua`); make sure your
+  Hyprland build supports the Lua configuration API. The `.bak` files are the
+  previous plain-text config kept for reference.
+- **Quickshell** is launched automatically from Hyprland (`qs`) and relies on
+  the Pipewire, UPower, Bluetooth and NetworkManager services above.
+- **Neovim** bootstraps its plugins on first launch via LazyVim; `git`,
+  `ripgrep` and `fd` are required for full functionality.
