-4. Change theme from User Themes settings
+1. Ensure GNOME Tweaks is installed.
+2. Ensure the GNOME Shell extension ["User Themes"](https://extensions.gnome.org/extension/19/user-themes/) is installed and enabled in [GNOME Extensions](https://apps.gnome.org/en-GB/Extensions/).
+3. Download `E-Ink.zip` from [Releases](https://github.com/fujimo-t/gnome-shell-theme-e-ink/releases).
+4. Place the `gnome-shell.css` file into `~/.themes/E-Ink/gnome-shell/`.

+
+### Additional steps for Ubuntu
+
+The dock styling will work only if the system is running the GNOME Shell extension ["Dash to Dock"](https://extensions.gnome.org/extension/307/dash-to-dock/), of which Ubuntu ships a modified version that is incompatible with this theme. To resolve this,
+
+1. Install ["Dash to Dock"](https://extensions.gnome.org/extension/307/dash-to-dock/).
+
+2. In Gnome Extensions, disable the extension "Ubuntu Dock" in the "System Extensions" section.
+
+3. Enable the extension "Dash to Dock".
+
+4. Open the settings of Dash to Dock. Under the "Appearance" section, ensure that "Use built-in theme" is toggled to the off position.
