 ## Is it safe to store my kdbx file in the cloud?
 While it may happen that someone gets access to your kdbx file in the cloud, there is still no need to worry: the purpose of encryption is to protect the data even in case someone gets the kdbx file! As long as you are using a safe master key, you're safe! [Key files](https://keepass.info/help/base/keys.html#keyfiles) can help with securing the database even more. 
 
+## Doesn't Keepass2Android create automatic backups?
+Yes and no. Yes: Keepass2Android stores the last successfully opened file as a read-only backup locally on the phone (unless you disable this is in the settings). This should make sure that even if the file gets destroyed during a save operation or gets deleted by accident, you should always have a version that can be opened. (Don't mix this up with the internal file cache which is not meant as a backup and can easily be overwritten even with a corrupt file. This internal file cache is meant for providing writable access even when the original file is not reachable, e.g. when you're offline.)
+No: The local backup has two shortcomings: It is only one backup and does not allow to revert to older versions. So if you deleted an entry from the database, it might be deleted in the local backup soon as well. The even more important shortcoming is that it is just a local backup. It won't help when your phone gets lost or broken. Please create additional backups on seperate storage!
+
 ## How do I backup the database?
 If you have stored your database on the cloud, you might rely on your cloud storage providers backups. Make sure they allow you to revert to older revisions in case the file gets corrupted for some reason.
 If you are working with a local database file, make sure you create regular backups. I suggest you have an aumotated mechanism, e.g. with FolderSync (Lite) which can copy local files from your device to other locations, e.g. your PC in a local network. You can also use USB or tools like MyPhoneExploror to transfer data to your PC. Or, you use a removable storage like an SD card which you keep in a safe place after making the backup.

+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; }
+}
