+## Installation
+
+This shows how to install Jirafeau by your own, it's quite simple but you can
+also use a [docker image](https://hub.docker.com/r/mojo42/jirafeau/) or build
+it yourself. Check [docker folder](docker/README.md) for more informations.
+
+System requirements:
+- PHP >= 5.6
+- Optional, but recommended: Git >= 2.7
+- No database required, no mail required

 
 

-# Screenshots
+Installation steps:
+- Clone the [repository](https://gitlab.com/mojo42/Jirafeau/) or download the latest [release](https://gitlab.com/mojo42/Jirafeau/tags) from GitLab onto your webserver
+- 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

-# 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```
+### Troubleshooting

 
 

-# Security
+If you have some troubles, consider the following cases

 
 

-```var``` directory contain all files and links. It is randomly named to limit access but you may add better protection to prevent un-authorized access to it.
+- Check your `/lib/config.local.php` file and compare it with `/lib/config.original.php`, the configuration syntax or a parameter may have changed
+- Check owner & permissions of your files
+- set `debug` option to `true` to check any warning or error

-```RedirectMatch 301 ^/var-.* http://my.service.jirafeau ```
+`RedirectMatch 301 ^/var-.* http://my.service.jirafeau`

 
 

-You should also remove un-necessessary write access once the installation is done (ex: configuration file).
+If you are using nginx, you can add the following to your $vhost.conf:

 
 

-An other obvious basic security is to let access users to the site by https.
+```nginx
+location ~ /var-.* {
+    deny all;
+    return 404;
+}
+```

 
 

-# Few notes about server side encryption
+If you are using lighttpd, you can deny access to `var` folder in your configuration:
+
+```
+$HTTP["url"] =~ "^/var-*" {
+         url.access-deny = ("")
+}
+```
+
+You should also remove un-necessessary write access once the installation is done (ex: configuration file).
+An other obvious basic security is to let access users to the site by HTTPS (make sure `web_root` in you `config.local.php` is set with https).
+
+## Server side encryption

 
 Data encryption can be activated in options. This feature makes the server encrypt data and send the decryt key to the user (inside download URL).

+The decrypt key is not stored on the server so if you lose the download URL, you won't be able to retrieve file content.
+Encryption is configured to use [XChaCha20-Poly1305](https://en.wikipedia.org/wiki/ChaCha20-Poly1305).

 In case of security troubles on the server, attacker won't be able to access files.
 
 By activating this feature, you have to be aware of few things:
 -  Data encryption has a cost (cpu) and it takes more time for downloads to complete once file sent.
 -  During the download, the server will decrypt on the fly (and use resource).

+- https://gitlab.com/mojo42/Jirafeau/blob/master/CONTRIBUTING.md

 
 

-If you have installed Jirafeau using git, it's pretty simple: just make a git pull and chown/chmod files who have the owner changed.
+## FAQ

 
 

-If you have installed Jirafeau just by uploading files on your server, you can take the [last version](https://gitlab.com/mojo42/Jirafeau/repository/archive.zip), overwrite files and chown/chmod files if needed.
+### Can I add a new language in Jirafeau?

 
 

-After upgrading, you can compare your ```lib/config.local.php``` and ```lib/config.original.php``` to see if new configuration items are available.
+Of course ! Translations are easy to make and no technical knowledge is required.

 
 

-If you have some troubles:
-- It should probably come from your ```lib/config.local.php``` (configuration syntax may have changed). Just compare it with ```lib/config.original.php```
-- Check owner/permissions of your files.

-### What is the difference between "delete link" and "delete file and links" in admin interface ?
+In order to know if a newly uploaded file already exist, Jirafeau will hash the file using md5 by default but other methods are available (see `file_hash` documentation in `lib/config.original.php`).

 - The button "delete link" will delete the reference to the file but might not destroy the file.
 - The button "delete file and links" will delete all references pointing to the file and will destroy the file.
