+KDSingleApplication
 -----------------
 This is a small static library used by Strawberry to prevent it from starting twice per user session.
 If the user tries to start strawberry twice, the main window will maximize instead of starting another instance.
-If you dynamically link to your systems version, you'll need two versions, one defined as QApplication and
+It is also used to pass command-line options through to the first instance.
-one as a QCoreApplication.
-It is included here because it is not packed by distros and is also used on macOS and Windows.

+# KDSingleApplication
+
+`KDSingleApplication` is a helper class for single-instance policy applications
+written by [KDAB](https://www.kdab.com).
+
+## Usage
+
+Currently the documentation is woefully lacking, but see the examples or tests
+for inspiration. Basically it involves:
+
+1. Create a `Q(Core|Gui)Application` object.
+2. Create a `KDSingleApplication` object.
+3. Check if the current instance is *primary* (or "master") or
+   *secondary* (or "slave") by calling `isPrimaryInstance`:
+    * the *primary* instance needs to listen from messages coming from the
+      secondary instances, by connecting a slot to the `messageReceived` signal;
+    * the *secondary* instances can send messages to the primary instance
+      by calling `sendMessage`.

-SingleApplication
-=================
-[![CI](https://github.com/itay-grudev/SingleApplication/workflows/CI:%20Build%20Test/badge.svg)](https://github.com/itay-grudev/SingleApplication/actions)
-
-This is a replacement of the QtSingleApplication for `Qt5` and `Qt6`.
-
-Keeps the Primary Instance of your Application and kills each subsequent
-instances. It can (if enabled) spawn secondary (non-related to the primary)
-instances and can send data to the primary instance from secondary instances.
-
-Usage
------
-
-The `SingleApplication` class inherits from whatever `Q[Core|Gui]Application`
-class you specify via the `QAPPLICATION_CLASS` macro (`QCoreApplication` is the
-default). Further usage is similar to the use of the `Q[Core|Gui]Application`
-classes.
-
-You can use the library as if you use any other `QCoreApplication` derived
-class:
-
-```cpp
-#include <QApplication>
-#include <SingleApplication.h>
-
-int main( int argc, char* argv[] )
-{
-    SingleApplication app( argc, argv );
-
-    return app.exec();
-}
-```
-
-To include the library files I would recommend that you add it as a git
-submodule to your project. Here is how:
-
-```bash
-git submodule add https://github.com/itay-grudev/SingleApplication.git singleapplication
-```
-
-**Qmake:**
-
-Then include the `singleapplication.pri` file in your `.pro` project file.
-
-```qmake
-include(singleapplication/singleapplication.pri)
-DEFINES += QAPPLICATION_CLASS=QApplication
-```
-
-**CMake:**
-
-Then include the subdirectory in your `CMakeLists.txt` project file.
-
-```cmake
-set(QAPPLICATION_CLASS QApplication CACHE STRING "Inheritance class for SingleApplication")
-add_subdirectory(src/third-party/singleapplication)
-target_link_libraries(${PROJECT_NAME} SingleApplication::SingleApplication)
-```
-
-
-The library sets up a `QLocalServer` and a `QSharedMemory` block. The first
-instance of your Application is your Primary Instance. It would check if the
-shared memory block exists and if not it will start a `QLocalServer` and listen
-for connections. Each subsequent instance of your application would check if the
-shared memory block exists and if it does, it will connect to the QLocalServer
-to notify the primary instance that a new instance had been started, after which
-it would terminate with status code `0`. In the Primary Instance
-`SingleApplication` would emit the `instanceStarted()` signal upon detecting
-that a new instance had been started.
-
-The library uses `stdlib` to terminate the program with the `exit()` function.
-
-Also don't forget to specify which `QCoreApplication` class your app is using if it
-is not `QCoreApplication` as in examples above.
-
-The `Instance Started` signal
------------------------------
-
-The SingleApplication class implements a `instanceStarted()` signal. You can
-bind to that signal to raise your application's window when a new instance had
-been started, for example.
-
-```cpp
-// window is a QWindow instance
-QObject::connect(
-    &app,
-    &SingleApplication::instanceStarted,
-    &window,
-    &QWindow::raise
-);
-```
-
-Using `SingleApplication::instance()` is a neat way to get the
-`SingleApplication` instance for binding to it's signals anywhere in your
-program.
-
-__Note:__ On Windows the ability to bring the application windows to the
-foreground is restricted. See [Windows specific implementations](Windows.md)
-for a workaround and an example implementation.
-
-
-Secondary Instances
--------------------
-
-If you want to be able to launch additional Secondary Instances (not related to
-your Primary Instance) you have to enable that with the third parameter of the
-`SingleApplication` constructor. The default is `false` meaning no Secondary
-Instances. Here is an example of how you would start a Secondary Instance send
-a message with the command line arguments to the primary instance and then shut
-down.
-
-```cpp
-int main(int argc, char *argv[])
-{
-    SingleApplication app( argc, argv, true );
-
-    if( app.isSecondary() ) {
-        app.sendMessage(  app.arguments().join(' ')).toUtf8() );
-        app.exit( 0 );
-    }
-
-    return app.exec();
-}
-```
-
-*__Note:__ A secondary instance won't cause the emission of the
-`instanceStarted()` signal by default. See `SingleApplication::Mode` for more
-details.*
-
-You can check whether your instance is a primary or secondary with the following
-methods:
-
-```cpp
-app.isPrimary();
-// or
-app.isSecondary();
-```
-
-*__Note:__ If your Primary Instance is terminated a newly launched instance
-will replace the Primary one even if the Secondary flag has been set.*
-
-Examples
---------
-
-There are three examples provided in this repository:
-
-* Basic example that prevents a secondary instance from starting [`examples/basic`](https://github.com/itay-grudev/SingleApplication/tree/master/examples/basic)
-* An example of a graphical application raising it's parent window [`examples/calculator`](https://github.com/itay-grudev/SingleApplication/tree/master/examples/calculator)
-* A console application sending the primary instance it's command line parameters [`examples/sending_arguments`](https://github.com/itay-grudev/SingleApplication/tree/master/examples/sending_arguments)
-
-API
----
-
-### Members
-
-```cpp
-SingleApplication::SingleApplication( int &argc, char *argv[], bool allowSecondary = false, Options options = Mode::User, int timeout = 100, QString userData = QString() )
-```
-
-Depending on whether `allowSecondary` is set, this constructor may terminate
-your app if there is already a primary instance running. Additional `Options`
-can be specified to set whether the SingleApplication block should work
-user-wide or system-wide. Additionally the `Mode::SecondaryNotification` may be
-used to notify the primary instance whenever a secondary instance had been
-started (disabled by default). `timeout` specifies the maximum time in
-milliseconds to wait for blocking operations. Setting `userData` provides additional data that will isolate this instance from other instances that do not have the same (or any) user data set.
-
-*__Note:__ `argc` and `argv` may be changed as Qt removes arguments that it
-recognizes.*
-
-*__Note:__ `Mode::SecondaryNotification` only works if set on both the primary
-and the secondary instance.*
-
-*__Note:__ Operating system can restrict the shared memory blocks to the same
-user, in which case the User/System modes will have no effect and the block will
-be user wide.*
-
----
-
-```cpp
-bool SingleApplication::sendMessage( QByteArray message, int timeout = 100 )
-```
-
-Sends `message` to the Primary Instance. Uses `timeout` as a the maximum timeout
-in milliseconds for blocking functions. Returns `true` if the message has been sent
-successfully. If the message can't be sent or the function timeouts - returns `false`.
-
----
-
-```cpp
-bool SingleApplication::isPrimary()
-```
-
-Returns if the instance is the primary instance.
-
----
-
-```cpp
-bool SingleApplication::isSecondary()
-```
-Returns if the instance is a secondary instance.
-
----
-
-```cpp
-quint32 SingleApplication::instanceId()
-```
-
-Returns a unique identifier for the current instance.
-
----
-
-```cpp
-qint64 SingleApplication::primaryPid()
-```
-
-Returns the process ID (PID) of the primary instance.
-
----
-
-```cpp
-QString SingleApplication::primaryUser()
-```
-
-Returns the username the primary instance is running as.
-
----
-
-```cpp
-QString SingleApplication::currentUser()
-```
-
-Returns the username the current instance is running as.
-
-### Signals
-
-```cpp
-void SingleApplication::instanceStarted()
-```
-
-Triggered whenever a new instance had been started, except for secondary
-instances if the `Mode::SecondaryNotification` flag is not specified.
-
----
-
-```cpp
-void SingleApplication::receivedMessage( quint32 instanceId, QByteArray message )
-```
-
-Triggered whenever there is a message received from a secondary instance.
-
----
-
-### Flags
-
-```cpp
-enum SingleApplication::Mode
-```
-
-*   `Mode::User` - The SingleApplication block should apply user wide. This adds
-    user specific data to the key used for the shared memory and server name.
-    This is the default functionality.
-*   `Mode::System` – The SingleApplication block applies system-wide.
-*   `Mode::SecondaryNotification` – Whether to trigger `instanceStarted()` even
-    whenever secondary instances are started.
-*   `Mode::ExcludeAppPath` – Excludes the application path from the server name
-    (and memory block) hash.
-*   `Mode::ExcludeAppVersion` – Excludes the application version from the server
-    name (and memory block) hash.
-
-*__Note:__ `Mode::SecondaryNotification` only works if set on both the primary
-and the secondary instance.*
-
-*__Note:__ Operating system can restrict the shared memory blocks to the same
-user, in which case the User/System modes will have no effect and the block will
-be user wide.*
-
----
-
-Versioning
-----------
-
-Each major version introduces either very significant changes or is not
-backwards compatible with the previous version. Minor versions only add
-additional features, bug fixes or performance improvements and are backwards
-compatible with the previous release. See [`CHANGELOG.md`](CHANGELOG.md) for
-more details.
-
-Implementation
---------------
-
-The library is implemented with a QSharedMemory block which is thread safe and
-guarantees a race condition will not occur. It also uses a QLocalSocket to
-notify the main process that a new instance had been spawned and thus invoke the
-`instanceStarted()` signal and for messaging the primary instance.
-
-Additionally the library can recover from being forcefully killed on *nix
-systems and will reset the memory block given that there are no other
-instances running.
-
-License
--------
-This library and it's supporting documentation are released under
-`The MIT License (MIT)` with the exception of the Qt calculator examples which
-is distributed under the BSD license.

+# Contribution guidelines
+
+Strawberry is an free and open-source project, it is possible and encouraged to participate in the development.
+You can also participate by answering questions, reporting bugs or helping with documentation.
+
+
+## Submitting a pull request
+
+You should start by creating a fork of the Strawberry repository using the GitHub
+fork button, after that you can clone the repository from your fork.
+Replace "username" with your own.
+
+
+### Clone the repository
+
+    git clone git@github.com:username/strawberry.git
+    cd strawberry
+
+
+### Setup the remote
+
+    git remote add upstream git@github.com:strawberrymusicplayer/strawberry.git
+
+
+### Create a new branch
+
+This creates a new branch from the master branch that you use for specific
+changes.
+
+    git checkout -b your-branch
+
+
+### Stage changes
+
+Once you've finished working on a specific change, stage the changes for
+a specific commit.
+
+Always keep your commits relevant to the pull request, and each commit as
+small as possible.
+
+    git add -p
+
+
+### Commit changes
+
+    git commit
+
+
+### Commit messages
+
+The first line should start with "Class:", which referer to the class
+that is changed. Don't use a trailing period after the first line.
+If this change affects more than one class, omit the class and write a
+more general message.
+You only need to include a main description (body) for larger changes
+where the one line is not enough to describe everything.
+The main description starts after two newlines, it is normal prose and
+should use normal punctuation and capital letters where appropriate.
+
+An example of the expected format for git commit messages is as follows:
+
+```
+class: Short explanation of the commit
+
+Longer explanation explaining exactly what's changed, why it's changed,
+and what bugs were fixed.
+
+Fixes #1234
+```
+
+
+### Push the changes to GitHub
+
+Once you've finished working on the changes, push the branch
+to the Git repository and open a new pull request.
+
+
+    git push origin your-branch
+
+
+### Update your fork's master branch
+
+    git checkout master
+    git pull --rebase origin master
+    git fetch upstream
+    git merge upstream/master
+    git push origin master
+
+
+### Update your branch
+
+    git checkout your-branch
+    git fetch upstream
+    git rebase upstream/master
+    git push origin your-branch --force-with-lease
+
+
+### Rebase your branch
+
+If you need fix any issues with your commits, you need to rebase your
+branch to squash any commits, or to change the commit message.
+
+    git checkout your-branch
+    git log
+    git rebase -i commit_sha~
+    git push origin your-branch --force-with-lease
+
+
+### Delete your fork
+
+If you do not plan to work more on Strawberry, please delete your fork from GitHub
+once the pull requests are merged.
