 If you store important information using Keepass2Android, you should know a little bit about what's going on:
 * Keepass2Android stores your password in an encrypted file. It is *your responsibility* to backup this file regularly and safely.
 * There is no way for anyone, including the app's author, to access the information stored in your password database without 
-  * having the database file
-  * knowing the master password (and additional second factor if you chose one)
-  This means that **if you forget the master password, your database is lost**! So make sure you remember the password and retain any second factor method (if one is used).
-* You might also want to think about:
-  * What happens if I have an accident? Should any trusted person be able to access my database?
-  * What happens if my phone gets lost or stolen? Do I know how to recover my database from a backup or the cloud?

 on how to set up a Keepass 2 database with Yubikey/OTP protection.<br>
 <br>
 After successful setup you should have the database file, e.g. yubi.kdbx, and the OTP auxiliary file, e.g. yubi.otp.xml, both in the same folder.<br>

 <p>Make sure you make <strong>both files</strong> available to Keepass2Android, e.g. by placing them both in your Dropbox.</p>
 <p>Now you should check your NDEF setup of the Yubikey NEO. Therefore, go to the Tools menu in the Yubico Personalization Utility. Select the same slot as used for OTPs with Keepass 2. The default setting for NDEF type and payload should work. If you experience
 problems, you may use the configuration as shown in this screenshot or simply press the &ldquo;Reset&rdquo; button:</p>

 In the password screen under &quot;Select master key type&quot; select &quot;Password &#43; OTP&quot;.</p>

 After loading the OTP auxiliary file, you should see a few text fields for entering the OTPs. Now swipe your YubiKey NEO at the back of your Android device. If you have multiple apps which can handle NFC actions, you might be prompted to select which app to
 use. Select Keepass2Android in this case. Swipe your YubiKey again until all OTP fields are filled. Note: You don't need to select the next text field, this is done automatically!<br>

 Don't forget to also enter your password and click OK. You will see the &ldquo;Saving auxiliary OTP file&hellip;&rdquo; dialog. Note that there is some encryption envolved which is probably fast on your PC but might take some time on your mobile device. You
 can reduce the look-ahead window length to speed this up.<br>

 <h2>&nbsp;</h2>
 <h2>A note about offline access</h2>
 <p>If your database is stored in the cloud or on the web, you can still access it if you have enabled file caching (which is on by default). With OTPs, this becomes a little bit more complicated: If you repeatedly open your datbase while being offline, the
 OTP counter stored on the Yubikey will be increased. Don&rsquo;t forget to synchronize the database (which will also synchronize the OTP auxiliary file) as soon as possible to avoid problems with accessing your database on other devices! If you often need
 to open the database while you&rsquo;re offline, consider increasing the look-ahead window length!</p>

 # What is Keepass2Android?
 Keepass2Android is a password manager app. It allows to store and retrieve passwords and other sensitive information in a file called "database". This database is secured with a so-called master password. The master password typically is a strong password and can be complemented with a second factor for additional security.
 The password database file can be synchronized across different devices. This works best using one of the built-in cloud storage options, but can also be performed with third-party apps. Keepass2Android is compatible with Keepass 1 and Keepass 2 on Windows and KeepassX on Linux.

-Additions allow you to add arbitrary C# to the generated classes
-before they are compiled.  This can be helpful for providing convenience
-methods or adding pure C# classes.
-
-== Adding Methods to Generated Classes ==
-
-Let's say the library being bound has a Rectangle class with a constructor
-that takes an x and y position, and a width and length size.  It will look like
-this:
-
-public partial class Rectangle
-{
-    public Rectangle (int x, int y, int width, int height)
-	{
-	    // JNI bindings
-	}
-}
-
-Imagine we want to add a constructor to this class that takes a Point and
-Size structure instead of 4 ints.  We can add a new file called Rectangle.cs
-with a partial class containing our new method:
-
-public partial class Rectangle
-{
-    public Rectangle (Point location, Size size) :
-	    this (location.X, location.Y, size.Width, size.Height)
-	{
-	}
-}
-
-At compile time, the additions class will be added to the generated class
-and the final assembly will a Rectangle class with both constructors.
-
-
-== Adding C# Classes ==
-
-Another thing that can be done is adding fully C# managed classes to the
-generated library.  In the above example, let's assume that there isn't a
-Point class available in Java or our library.  The one we create doesn't need
-to interact with Java, so we'll create it like a normal class in C#.
-
-By adding a Point.cs file with this class, it will end up in the binding library:
-
-public class Point
-{
-    public int X { get; set; }
-	public int Y { get; set; }

-Additions allow you to add arbitrary C# to the generated classes
-before they are compiled.  This can be helpful for providing convenience
-methods or adding pure C# classes.
-
-== Adding Methods to Generated Classes ==
-
-Let's say the library being bound has a Rectangle class with a constructor
-that takes an x and y position, and a width and length size.  It will look like
-this:
-
-public partial class Rectangle
-{
-    public Rectangle (int x, int y, int width, int height)
-	{
-	    // JNI bindings
-	}
-}
-
-Imagine we want to add a constructor to this class that takes a Point and
-Size structure instead of 4 ints.  We can add a new file called Rectangle.cs
-with a partial class containing our new method:
-
-public partial class Rectangle
-{
-    public Rectangle (Point location, Size size) :
-	    this (location.X, location.Y, size.Width, size.Height)
-	{
-	}
-}
-
-At compile time, the additions class will be added to the generated class
-and the final assembly will a Rectangle class with both constructors.
-
-
-== Adding C# Classes ==
-
-Another thing that can be done is adding fully C# managed classes to the
-generated library.  In the above example, let's assume that there isn't a
-Point class available in Java or our library.  The one we create doesn't need
-to interact with Java, so we'll create it like a normal class in C#.
-
-By adding a Point.cs file with this class, it will end up in the binding library:
-
-public class Point
-{
-    public int X { get; set; }
-	public int Y { get; set; }

-== Input Jar ==
-
-This is the jar that bindings should be generated for.

-For example, if you were binding the Google Maps library, this would

-== Reference Jars ==
-
-These are jars that are referenced by the input jar.  C# bindings will

-# How to build Keepass2Android
-
-## Overview
-
-Keepass2Android is a Mono for Android app. This means that you need Xamarin's Mono for Android to build it. However, it also uses several components written in Java, so there are also Android-Studio projects involved. To make things even worse, parts of the keyboard and kdb-library are written in native code.
-The current build-scripts assume that the native libraries are already built (they are included in the repo). 
-
-To build KP2A from scratch, make sure that you have Xamarin's Mono for Android installed and also install Android Studio. Make sure that both point to the same Android SDK location.
-
-## Prerequisites
-
- Install Xamarin.Android
- Fetch all submodules (`git submodule init && git submodule update`)
-
-## Build
-
-### On Windows
-
-```bat
-cd build-scripts
-build-java.bat
-build-xamarin.bat
-```
-
-build-java.bat will call gradlew for several Java modules. build-xamarin.bat will first make sure that you have all files at their place. (There is a "secret" file for Dropbox SDK keys which is not in the repo, this is replaced with a dummy file. There are also different Android Manifest files depending on the configuration which is selected by calling the appropriate script.)
-
-**Notes:**
-
- - For building the java parts, it is suggested to keep a short name (e.g. "c:\projects\keepass2android") for the root project directory. Otherwise the Windows path length limit might be hit when building.
- - Before building the java parts, make sure you have set the ANDROID_HOME variable or create a local.properties file inside the directories with a gradlew file. It is recommended to use the same SDK location as that of the Xamarin build.
-
-### On Linux
-
- Install [Mono](https://www.mono-project.com/)
- Install Xamarin.Android
-  - Option 1: Use the mono-project [CI builds](https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android-linux/lastSuccessfulBuild/Azure/)
-  - Option 2: [Build it from source](https://github.com/xamarin/xamarin-android/blob/master/Documentation/README.md#building-from-source)
- Setup your environment:
-  - Add `xabuild` to your path: `export PATH=/path/to/xamarin.android-oss/bin/Release/bin/:$PATH`
-  - Setup your `ANDROID_HOME` if it's not already: `export ANDROID_HOME=/path/to/android/`
-  - Alternatively, you can set your `ANDROID_SDK_PATH` and `ANDROID_NDK_PATH`.
- Build [jar2xml](https://github.com/xamarin/jar2xml) and copy `jar2xml.jar` to `/path/to/xamarin.android-oss/bin/Release/lib/xamarin.android/xbuild/Xamarin/Android/`
- Install [libzip](https://libzip.org/) for your distribution.
-  - Note: Xamarin seems to require `libzip4`, yet most distributions only ships `libzip5`. As a dirty workaround, it's possible to symlink `libzip.so.5` to `libzip.so.4`. Luckily, it appears to be working.
-  - `sudo ln -s /usr/lib/libzip.so.5 /usr/lib/libzip.so.4`
- Install NuGet dependencies:
-  - `cd src/ && nuget restore KeePass.sln`
- Build:
-  - Option 1: `cd build-scripts && ./build-all.sh`
-  - Option 2:
-    - Build the Java parts: `cd build-scripts/ && ./build-java.sh`
-    - Build the Xamarin parts: `./build-xamarin.sh`
-    - Build the signed APK: `./build-apk.sh`
- Enjoy:
-  - `adb install ../keepass2android/bin/Debug/keepass2android.keepass2android_debug-Signed.apk`
