+# Introduction
+
+Welcome to the official Jirafeau project, an [Open-Source software](http://en.wikipedia.org/wiki/Open-source_software).
+
+Jirafeau is a web site permitting to upload a file in a simple way and give an unique link to it.
+
+A demonstration of the latest version is available on [jirafeau.net](http://jirafeau.net/)
+

+- Preview content in browser (if possible)
+- Optional Password protection (for uploading or downloading)
+- Time limitation
+- Option to self-destruct after reading
+- Simple language support :gb: :fr: :de: :it:
+- Small administration interface
+- File level [Deduplication](http://en.wikipedia.org/wiki/Data_deduplication) for storage optimization
+- A basic Terms Of Service which can be adapted to your needs
+- Shortened URLs using base 64 encoding

+- Skins
+...
+
+Jirafeau is a fork of the original project [Jyraphe](http://home.gna.org/jyraphe/) based on the 0.5 (stable version) with a **lot** of modifications.
+
+As it's original project, Jirafeau is made in the [KISS](http://en.wikipedia.org/wiki/KISS_principle) way (Keep It Simple, Stupid).
+
+Jirafeau project won't evolve to a file manager and will focus to keep a very few dependencies

+
+# 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```
+
+# Security
+
+```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.
+You have several options:
+- Configure a ```.htaccess```
+- Move var folder to a place on your server which can't be directly accessed
+- Disable automatic listing on your web server config or place a index.html in var's sub-directory (this is a limited solution)
+
+If you are using Apache, you can add the following lineto your configuration to prevent people to access to your ```var``` folder:
+
+```RedirectMatch 301 ^/var-.* http://my.service.jirafeau ```
+
+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.
+
+# Few notes about 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 loose an url, you won't be able to retrieve file content.
+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).
+- This feature needs to have the mcrypt php module.
+- File de-duplication will stop to work (as we can't compare two encrypted files).
+- Be sure you server do not log client's requests.
+- Don't forget to activate https.
+
+In a next step, encryption will be made by the client (in javascript), see issue #10.

+# FAQ
+
+### Can I add a new language in Jirafeau ?
+
+Of-course ! Translations are easy to make and no technical knowledge is required.
+
+Simply go to [Jirafeau's Weblate](https://hosted.weblate.org/projects/jirafeau/master/)
+
+If you want to add a new language in the list, feel free to contact us or leave a comment in #9
+
+### How do I upgrade my Jirafeau ?
+
+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.
+
+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.
+
+After upgrading, you can compare your ```lib/config.local.php``` and ```lib/config.original.php``` to see if new configuration items are available.
+
+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.
+
+Anyway you should off-course make a backup of your current installation before doing anything :)
+
+### How can I limit upload access ?
+
+There are two ways to limit upload access (but not download):
+- you can set one or more passwords in order to access the upload interface, or/and
+- you can configure a list of authorized IP ([CIDR notation](http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#CIDR_notation)) which are allowed to access to the upload page
+
+Check documentation of ```upload_password``` and ```upload_ip``` parameters in [lib/config.original.php](https://gitlab.com/mojo42/Jirafeau/blob/master/lib/config.original.php).
+
+### I found a bug, what should I do ?
+
+Feel free to open a bug in the [gitlab's issues](https://gitlab.com/mojo42/Jirafeau/issues)
+
+### How to set maximum file size ?
+
+If your browser supports HTML5 file API, you can send files as big as you want.
+
+For browsers who does not support HTML5 file API, the limitation come from PHP configuration.
+You have to set [post_max_size](http://php.net/manual/en/ini.core.php#ini.post-max-size) and [upload_max_filesize](http://php.net/manual/en/ini.core.php#ini.upload-max-filesize) in your php configuration.
+
+If you don't want to allow unlimited upload size, you can still setup a maximal file size in Jirafeau's setting (see ```maximal_upload_size``` in your configuration)
+
+### How can I edit an option ?
+
+Documentation of all default options are located in [lib/config.original.php](https://gitlab.com/mojo42/Jirafeau/blob/master/lib/config.original.php)
+If you want to change an option, just edit your ```lib/config.local.php```
+
+### How can I access the admin interface ?
+
+Just go to ```/admin.php```
+
+### How can I use the scripting interface ?
+
+Simply go to ```/script.php``` with your web browser.
+
+### My downloads are incomplete or my uploads fails
+
+Be sure your PHP installation is not using safe mode, it may cause timeouts.
+
+### Why forking ?
+
+The original project seems not to be continued anymore and I prefer to add more features and increase security from a stable version.
+
+### What can we expect in the future ?
+
+Check [issues](https://gitlab.com/mojo42/Jirafeau/issues) to check open bugs and incoming new stuff :)
+
+### What is the Jirafeau's license ?
+
+Jirafeau is licensed under [AGPLv3](https://gitlab.com/mojo42/Jirafeau/blob/master/COPYING)
+
+### How do I modify the TOS (terms of use) ?
+
+Just edit ```tos.php``` and configure ```$org``` and ```$contact``` variables.
+
+### What about this file deduplication thing ?
+
+Jirafeau use a very simple file level deduplication for storage optimization.
+
+This mean that if some people upload several times the same file, this will only store one time the file and increment a counter.
+
+If someone use his delete link or an admin cleans expired links, this will decrement the counter corresponding to the file.
+
+If the counter falls to zero, the file is destroyed.
+
+### What is the difference between "delete link" and "delete file and links" in admin interface ?
+
+As explained in the previous question, files with the same md5 hash are not duplicated and a reference counter stores the number of links pointing to a single file.
+So:
+- 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.
