+## DISCLAMER
+
+This project is a fork of the [discontinued project](https://gitlab.com/mojo42/Jirafeau/) by [Jérôme Jutteau](https://gitlab.com/mojo42/).
+
+If you've also forked the original project, feel free to mention it in [comments](https://gitlab.com/mojo42/Jirafeau/-/issues/360). Jérôme will add it there.
+
+In this repository we are aiming to continue development of the original Jirafeau project. Feel free to contribute to this fork by participating in discussions and providing merge requests, so we can build the best version of Jirafeau together!

 ## Installation
 

--  [Download](https://gitlab.com/mojo42/Jirafeau/repository/archive.zip) the last version of Jirafeau from GitLab
--  Upload files on your web server
--  Don't forget to set owner of uploaded files if you need to
--  Get your web browser and go to you install location (e.g. ```http://your-web-site.org/jirafeau/```) and follow instructions
--  Some options are not configured from the minimal installation wizard, you may take a look at option documentation in ```lib/config.original.php``` and customize your ```lib/config.local.php```
-
-Note that ```lib/config.local.php``` is auto-generated during the installation.
-
-If you don't want to go through the installation wizard, you can just copy ```config.original.php``` to ```config.local.php``` and customize it.
-
-## Upgrade
-
-### General procedure for all versions
-
-1. Backup your Jirafeau installation!
-2. Block access to Jirafeau
-3. Checkout the new version with Git using the [tagged release](https://gitlab.com/mojo42/Jirafeau/tags)
-   * If you have installed Jirafeau just by uploading files on your server, you can download the desired version, overwrite/remove all files and chown/chmod files if needed. Keep a backup of your local configuration file tough.
-4. With you browser, go to your Jirafeau root page
-5. Follow the installation wizard, it should propose you the same data folder or even update automatically
-7. Check your ```/lib/config.local.php``` and compare it with the ```/lib/config.original.php``` to see if new configuration items are available
-
-### From version 1.0 to 1.1
-
-1. The download URL changed
-   * Add a rewrite rule in your web server configuration to rename ```file.php``` to ```f.php``` to make older, still existing links work again
-1. The default skin changed
-   * Optionally change the skin in ```lib/config.local.php``` to »courgette«
-
-### From version 1.2.0 to 2.0.0
-
-1. The "Terms of Service" text file changed
-   * To reuse previous changes to the ToS, move the old ```/tos_text.php``` file to ```/lib/tos.local.txt``` and remove all HTML und PHP Tags, leaving a regular text file

+- Set owner & group according to your webserver
+- A) Setup with the installation wizard (web):
+  - Open your browser and go to your installed location, eg. `https://example.com/jirafeau/`
+  - The script will redirect to you to a minimal installation wizard to set up all required options
+  - All optional parameters may be set in `lib/config.local.php`, take a look at `lib/config.original.php` to see all default values
+- B) Setup without the installation wizard (cli):
+  - Just copy `lib/config.original.php` to `lib/config.local.php` and customize it
