 ## Prerequisites
 
 ℹ️ Read the [prerequisites section](https://github.com/invoiceninja/dockerfiles/wiki/prerequisites) carefully as you need all of these information for a proper setup.
 
-Additionally you need to have proper [TLD (Top Level Domain)](https://en.wikipedia.org/wiki/Top-level_domain) on a server that is publicly reachable (with a public IP). This is necessary for Caddy to correctly obtain the TLS certificate.  
-Also check the [Caddy automatic https requirements](https://caddyserver.com/docs/automatic-https).

 ⚠️ If you are missing either one of these additional prerequisites, then this setup does not work for you. Please check the [setup with nginx](https://github.com/invoiceninja/dockerfiles/wiki/docker-composee-with-nginx) instead.
 
+Even if not preferred, you can also use `https://localhost` to run IN. With that you only get a self-signed certificate and issues in your browser. Make sure you know the risk and consequences and how to tackle them.

 ## Guide for Invoice Ninja 4
 
+### 📁 Create a new folder
+
+First we need an empty folder where our docker files for IN 4 will reside.
+
+_Command_: `mkdir ~/invoiceninja5; cd ~/invoiceninja4`
+
+### 💻 Clone this repository
+
+Now we need to clone this repository to get all the files necessary to corretctly configure and run IN 4 with Docker Compose.
+
+_Command_: `git clone https://github.com/invoiceninja/dockerfiles.git .`
+
+### 🔨 Configure your installation
+
+To get the complete overview what things can be configured please check the [`docker-compose.yml`](https://github.com/invoiceninja/dockerfiles/blob/master/docker-compose.yml). Each section and value that can or should be configured is commented.
+
+Things you definately should check and change:
+
+* `APP_URL`: Environment variable where to reach your installation. This should be your valid TLD domain.
+* Ports: Ports are configured for `80` and `443`. Make sure they are open and not blocked by some other service.
+* Image: Set this to `invoiceninja/invoiceninja:alpine-4` to get the most recent version of IN 4
+* Database settings: You can find the default settings in the [`docker-compose.yml` file at the db service](https://github.com/invoiceninja/dockerfiles/blob/master/docker-compose.yml#L54). So for the `app` service the environment variables that should be added are:
+  * `DB_HOST`=db
+  * `DB_USERNAME`=ninja
+  * `DB_PASSWORD`=ninja
+  * `DB_DATABASE`=db-ninja-01
+
+### 🚀 Run your installation
+
+After you finished the afore mentioned steps you can now run your installation.
+
+_Command_: `docker-compose up -d`
+
+This will run Invoice Ninja 4 with the configuration made. You should now be able to reach your installation at the `APP_URL` configured.
