+## Build and run
+
+Run directly:
+
+```bash
+go run ./cmd/vcom
+```
+
+Build local binary:
+
+```bash
+go build -o vcom ./cmd/vcom
+```
+
+## Installation
+
+### NixOS / Nix
+
+Run directly from the flake:
+
+```bash
+nix run github:vrubelroman/vcom?ref=v0.1.9
+```
+
+Install into user profile:
+
+```bash
+nix profile add github:vrubelroman/vcom?ref=v0.1.9
+```
+
+The Nix package wraps `vcom` with `ueberzugpp` in `PATH`, so image preview works in non-`kitty` terminals out of the box.
+
+### Debian / Ubuntu
+
+Download the release `.deb` for `v0.1.9`, then install:
+
+```bash
+sudo apt install ./vcom_0.1.9_amd64.deb
+```
+
+The Debian package declares `ueberzug` (or `ueberzugpp` where available) as a dependency for image preview outside `kitty`.
+
+### Arch Linux
+
+A `PKGBUILD` is included in the repository:
+
+```bash
+makepkg -si
+```
+
+The Arch package depends on `ueberzugpp`, so non-`kitty` image preview is installed together with `vcom`.

 ## Font requirement (icons)
 
 For file icons, `vcom` expects a Nerd Font in your terminal profile.
