 ## Building
 
+This project uses [Just](https://just.systems/) as its command runner to help
+run cargo with a consistent interface. You are recommended to get it with Nix,
+using the default devshell which provides Just.
+
 ```bash
-# Build all compilable crates
+# Build everything (core crates + UI)
+$ just build
+
+# Build only core crates (cargo)
+$ just build-core
+
+# Build only the UI (uses dx - see note below)
+$ just build-ui
+```
+
+> [!IMPORTANT]
+> The Dioxus UI (`pinakes-ui`) must be built with `dx` (Dioxus CLI) to compile
+> SCSS stylesheets. Using `cargo build -p pinakes-ui` will not work correctly as
+> it skips the SCSS compilation step. This was previously "remedied" with an
+> intermediate build wrapper, which turned out to be fragile. It is highly
+> recommended that you prefer `just` to build.
+
+Manual build commands if not using Just:
+
+```bash
+# Core crates (standard cargo)
 $ cargo build -p pinakes-core -p pinakes-server -p pinakes-tui
 
-# The Dioxus UI requires GTK3 and libsoup system libraries:
+# UI (requires Dioxus CLI for SCSS compilation)

 # On Debian/Ubuntu: apt install libgtk-3-dev libsoup-3.0-dev libwebkit2gtk-4.1-dev
 # On Fedora: dnf install gtk3-devel libsoup3-devel webkit2gtk4.1-devel
 # On Nix: Use the dev shell, everything is provided :)
