+# ModernKeePassLib
+
+This is my adaptation of the KeePassLib (KeePass library) for the Universal Windows Platform and Windows Runtime (WinRT).  
+It aims at introducing as little change as possible to the original library: overall, except for namespace changes and some added classes (see below), there is almost no change.  
+
+Download the Nuget package [here](https://www.nuget.org/packages/ModernKeePassLib)
+
+# Features
+- Custom implementation of the System.Security.Cryptography.HashAlgoritm class by using WinRT equivalents
+- Use of BouncyCastle PCL to implement AES key derivation features
+- Lots of small changes in .NET methods (UTF8 instead of ASCII, string.)
+- Disabled native functions (because not compatible with WinRT)
+- Use of Splat for GfxUtil

-# Introduction
-TODO: Give a short introduction of your project. Let this section explain the objectives or the motivation behind this project. 
+[<img src="https://geogeob.visualstudio.com/_apis/public/build/definitions/04291454-0e79-47a4-9502-5bd374804ccf/2/badge"/>](https://geogeob.visualstudio.com/_apis/public/build/index?definitionId=2)
 
-# Getting Started
-TODO: Guide users through getting your code up and running on their own system. In this section you can talk about:
-1.	Installation process
-2.	Software dependencies
-3.	Latest releases
-4.	API references
+# Introduction
+**ModernKeePass** is port of the classic Windows application KeePass 2.x for the Windows Store.  
+It does not aim to be feature perfect, but aims at being simple to use and user-friendly.
+
+You can get it [here](https://www.microsoft.com/fr-fr/store/p/modernkeepass/9mwq48zk8nhv?rtc=1)
+
+# Features
+- Works on Windows 10, 8.1 and RT
+- Read and write support of KDBX files version 2, 3 and 4
+- Open database with password and key file
+- Create new databases
+- Create, edit and delete groups
+- Create, edit and delete entries
+- Generate passwords for entries
+- Use Recycle Bin
+- Search entries
+- Use Semantic Zoom to see your entries in a grouped mode
+- List recently opened databases
+- Open database from Windows Explorer
+- Change database encryption
+- Change database compression
+- Change database key derivation
+- Displays entry colors and icons (set in KeePass)
 
 # Build and Test
-TODO: Describe and show how to build your code and run the tests. 
+1. Clone the repository
+2. Build the main app (the library reference dll is actually a NuGet dependency, built from the [**ModernKeePassLib** project](../ModernKeePassLib/README.md))
+3. Edit the `.appxmanifest` file to select another certificate (you can create one using Visual Studio or *certutil.exe*)
 
 # Contribute
-TODO: Explain how other users and developers can contribute to make your code better. 
+I'm not the best at creating nice assets, so if anyone would like to contribute some nice icons, it would be awesome :)
+Otherwise, there are still many things left to implement:
+- Entry custom fields
+- Multi entry selection (for delete, or move)
+- Move entries from a group to another
+- Create key files
+- Open database from URL (and maybe some clouds?)
