-You can go multiple routes to setup and run Paperless:
+# Installation
 
--   [Use the script to setup a Docker install](#docker_script)
--   [Use the Docker compose templates](#docker)
--   [Build the Docker image yourself](#docker_build)
--   [Install Paperless-ngx directly on your system manually ("bare metal")](#bare_metal)
--   A user-maintained list of commercial hosting providers can be found [in the wiki](https://github.com/paperless-ngx/paperless-ngx/wiki/Related-Projects)
-
-The Docker routes are quick & easy. These are the recommended routes.
-This configures all the stuff from the above automatically so that it
-just works and uses sensible defaults for all configuration options.
-Here you find a cheat-sheet for docker beginners: [CLI
-Basics](https://www.sehn.tech/refs/devops-with-docker/)
-
-The bare metal route is complicated to setup but makes it easier should
-you want to contribute some code back. You need to configure and run the
-above mentioned components yourself.
-
-### Use the Installation Script {#docker_script}
-
-Paperless provides an interactive installation script to setup a Docker Compose
-installation. The script asks for a couple configuration options, and will then create the
-necessary configuration files, pull the docker image, start Paperless-ngx and create your superuser
-account. The script essentially automatically performs the steps described in [Docker setup](#docker).
-
-1.  Make sure that Docker and Docker Compose are [installed](https://docs.docker.com/engine/install/){:target="\_blank"}.
-
-2.  Download and run the installation script:
+!!! tip "Quick Start"
 
+    If you just want Paperless-ngx running quickly, use our installation script:
     ```shell-session
     bash -c "$(curl --location --silent --show-error https://raw.githubusercontent.com/paperless-ngx/paperless-ngx/main/install-paperless-ngx.sh)"
     ```

+## Installation Script {#docker_script}
+
+Paperless-ngx provides an interactive script for Docker Compose setups.
+It asks a few configuration questions, then creates the required files,
+pulls the image, starts the containers, and creates your [superuser](usage.md#superusers)
+account. In short, it automates the [Docker Compose setup](#docker) described below.
+
+#### Prerequisites
+
+-   Docker and Docker Compose must be [installed](https://docs.docker.com/engine/install/){:target="\_blank"}.
+-   macOS users will need [GNU sed](https://formulae.brew.sh/formula/gnu-sed) with support for running as `sed` as well as [wget](https://formulae.brew.sh/formula/wget).

+
+#### After installation
+
+Paperless-ngx should be available at `http://127.0.0.1:8000` (or similar,
+depending on your configuration) and you will be able to login with the
+credentials you provided during the installation script.
