 community.
 
+## Go Slow, Make a Plan
+
+There is nothing really easy about diving into this system administration work
+and getting things up and running but on the other hand there is nothing so
+complicated that it cannot be figured out. In short: you can do it!
+
+The two most important things to take into consideration before starting are
+
+- Choosing a "route" through this documentation (see just below).
+- Reading the [Prerequisites] section very closely and trying to
+  understand, **before you dive in**, how things will work with your Raspberry
+  Pi and how it is setup and connected to the internet.
+
+There are 3 routes you can take through this documentation:
+
+- **Cloning**: Skipping the entire thing and simply cloning a pre-made copy of
+  a Bibliotecha SD-card onto your new SD-card. You can then plug the SD-card
+  into your Raspberry Pi and Bibliotecha will be ready to go. Skip to the
+  [Cloning] section for more. This is the *moving really fast and don't have
+  time* option.
+
+- **Automated**: You follow the documentation below: [Prerequisites],
+  [Pre-installation] and finally [Automated Installation]. This allows you do
+  to the initial setup and then a run convenient installation script which
+  takes care of installing Bibliotecha. This is the *moving fast but still want
+  to be involved with the process* option.
+
+- **Manual**: You follow the documentation below: [Prerequisites],
+  [Pre-installation] and finally [Manual Installation]. You do everything
+  yourself to get from start to finish. Everything that would be done in the
+  automated script, you do yourself. This is the *I have time and want to learn
+  a lot* option.

-system.
 
 You should follow the [official setup documentation] on the Raspberry Pi website
 in order to get your board up and running. You will need it to have access to
 the internet in order to download the necessary packages as well as access to
 the command-line.
 
+!!! warning
+
+    You **must** use an Ethernet cable to connect your Raspberry Pi to your
+    router and not use the Wifi connection. This is because the Bibliotecha
+    install process will overwrite the Wifi configuration. So, you also
+    **must** have access to your router before going further.
+
+Here is an example of what we did.
+
+*Below: Here we plug the gray ethernet cable into the router.*
+
+![Router](img/router.png)
+
+*Below: And then we plug that same gray ethernet cable into the Raspberry Pi.*
+
+![Pi](img/pi.png)
+
+!!! note
+
+    The ethernet cable is not required after you finish the installation
+    of Bibliotecha! Your Bibliotecha can now operate independent of an internet
+    connection and offers its own Wifi access point. So, the ethernet cable is only
+    required for the installation process. Later, if you need to do an update or
+    some maintenance which requires an internet connection, you can plug it back in
+    and [make sure to check this tip].
+
 The current latest [Raspberry Pi 3 B+] model is recommended. This model is
 chosen because it offers a built-in wireless card for convenient networking and
 a sufficient memory allowance of 1GB. It is possible to use other models of
 board but they should at least provide these guarantees.
