Your changes now do not mention the Contao Manager anymore, wasn't that the original goal?

The aim was to make it clear that the “Install Tool” was only available or necessary up to version 4.13

Yes, but now you are not explaining anymore what to do instead.

Yes, but now you are not explaining anymore what to do instead.

Change the Quickstart part:

• As soon as the Contao Manager has installed all packages, the database must be updated. To do this you can use theContao Install Tool (Contao 4.13 LTS). From Contao 5 onwards, this is no longer necessary, the corresponding information is requested via the Contao Manager.

• Sobald der Contao Manager alle Pakete installiert hat, muss die Datenbank aktualisiert werden. Dazu kannst du
  dasContao Install Tool (Contao 4.13 LTS) verwenden. Ab Contao 5 ist dies nicht mehr notwendig,
  entsprechende Angaben werden über den Contao Manager abgefragt.

Should this be fine, I will take it over again in the other areas?

@fkaminski see my review above, I think that should make it more clear.

Btw., when linking to other articles, it would be better to use{{% ref … %}} instead :)

Thank You. The last commit is based on your Suggestions (incl. ref usage).
