-- QT 5.12 *(lower versions might work but it wasn't tested)*
-- CMake 3.4 or higher
+- QT 5 or 6
+- CMake 3.10 or higher
 - qxmpp 1.1.0 or higher

 - KDE Frameworks: kwallet (optional)
@@ -108,6 +108,7 @@ Here is the list of keys you can pass to configuration phase of `cmake ..`:
 - `WITH_KIO` - `True` builds the `KIO` capability module if `KIO` is installed and if not goes to `False`. `False` disables `KIO` support (default is `True`)
 - `WITH_KCONFIG` - `True` builds the `KConfig` and `KConfigWidgets` capability module if such packages are installed and if not goes to `False`. `False` disables `KConfig` and `KConfigWidgets` support (default is `True`)
 - `WITH_OMEMO` - `True` builds the OMEMO encryption, requires `qxmpp` of version >= 1.5.0 built with OMEMO support. `False` disables OMEMO support (default is `False`)
+- `QT_VERSION_MAJOR` - `6` builds against Qt 6, `5` builds against Qt 6, corresponding version of lmdbal and qxmpp should be installed. By default it picks your system default Qt

-/**
- @ short Simple encrypt*ion and decryption of strings and byte arrays
- 
- This class provides a simple implementation of encryption and decryption
- of strings and byte arrays.
- 
- @warning The encryption provided by this class is NOT strong encryption. It may
- help to shield things from curious eyes, but it will NOT stand up to someone
- determined to break the encryption. Don't say you were not warned.
- 
- The class uses a 64 bit key. Simply create an instance of the class, set the key,
- and use the encryptToString() method to calculate an encrypted version of the input string.
- To decrypt that string again, use an instance of SimpleCrypt initialized with
- the same key, and call the decryptToString() method with the encrypted string. If the key
- matches, the decrypted version of the string will be returned again.
- 
- If you do not provide a key, or if something else is wrong, the encryption and
- decryption function will return an empty string or will return a string containing nonsense.
- lastError() will return a value indicating if the method was succesful, and if not, why not.
- 
- SimpleCrypt is prepared for the case that the encryption and decryption
- algorithm is changed in a later version, by prepending a version identifier to the cypertext.

+  <description>
+    <p>
+      Squawk is a lightweight XMPP desktop messenger.
+      The primary objective of this project is to offer
+      you a fast and user-friendly messaging experience
+      that closely aligns with your system’s style, while
+      also minimizing resource consumption.
+    </p>
+    <p>
+      Squawk is still at a very early stage and might not suit
+      everyone but you are welcome to try it out.
