+Code style
+----------
+
+The recommended code style is Qt one. See [this document](https://wiki.qt.io/Qt_Coding_Style)
+for more details. To avoid manual labor there is automatic cmake target named
+`clangformat` (see below). Some additional detail see below.
+
+* Indent is only spaces. 4 spaces.
+* It is highly recommended to name private variables with `m_` prefix (`m_foo`).
+  There is no exceptions for properties.
+* Avoid to create a large methods. Exception: if method contains lambda functions.
+* If some method is called only once, it is recommended to use lambda functions.
+  Exception is `Q_INVOKABLE` methods.
+* STL containers are not recommended, use Qt ones instead.
+* In other hand Qt specific variables types (`qint`, `qfloat`, etc) are not
+  recommended.
+* Do not repeat yourself ([DRY](https://en.wikipedia.org/wiki/Don't_repeat_yourself)).
+* Headers declaration:
+    * Include only those headers which are strictly necessary inside headers. Use
+      forward class declaration instead. Exception is base class header declaration.
+    * In a`*.cpp` file header declaration should have the following order separated
+      by a new line in the alphabet order:
+        1. Class header.
+        2. KDE specific headers.
+        3. Qt specific headers.
+        4. Third party headers.
+        5. Project headers.
+    * Any header should have [include guard](https://en.wikipedia.org/wiki/Include_guard)
+      named as `CLASSNAMECAPS_H`
+* If any `#if` directive is used condition should be mentioned in `#endif`:
+
+  ```
+  #if (FOO)
+  someCodeInside();
+  #endif /* FOO */
+  ```
+
+* `Q_PROPERTY` macro is allowed and recommended for QObject based classes.
+* Qt macros (e.g. `signals`, `slots`, `Q_OBJECT`, etc) are allowed. In other hand
+`Q_FOREACH` (`foreach`) is not allowed use `for (auto foo : bar)` instead.
+* Current project standard is **C++11**.
+* Do not use C-like code:
+    * C-like style iteration if possible. Use `for (auto foo : bar)` and
+      `std::for_each` instead if possible. It is also recommended to use iterators.
+    * C-like casts, use `const_cast`, `static_cast`, `dymanic_Cast` instead. Using
+      of `reinterpret_cast` is not recommended. It is highly recommended to use
+      `dynamic_cast` with the exception catching. It is also possible to use
+      `qvariant_cast` if required. Exception is class constructors, e.g.:
+
+      ```
+      char c = 'c';
+      std::string s = "string";
+      qDebug() << QString("some string") << QChar(c) << QString(s);
+      ```
+
+    * C-like `NULL`, use `nullptr` instead.
+* It is highly recommended to avoid implicit casts.
+* Abstract classes (which have at least one pure virtual method) are allowed.
+* Templates are allowed and recommended. Templates usually should be described
+  inside header not source code file.
+* Hardcode is not recommended. But it is possible to use cmake variables to
+  configure some items during build time.
+* Build should not require any additional system variable declaration/changing.
+* Any line should not end with space.
+* Do not hesitate move public methods to private one if possible.
+* Do not hesitate use `const` modifier. In other hand `volatile` modifier is not
+  recommended.
+* New lines rules:
+    * One line after license header.
+    * One line between header group declaration (see above).
+    * Two lines after header declaration and before declaration at the end of a
+      file.
+    * One line after class and types forward declarations in headers.
+    * One line before each method modifiers (`public`, `public slots`, etc).
+    * Two lines between methods inside source code (`*.cpp`).
+    * One line after `qCDebug()` information (see below).
+    * One line inside a method to improve code reading.
+* Each destructor should be virtual.
+* Class constructor should have default arguments. Use `QObject *parent` property
+  for QObject based classes.
+* QObject based classes constructors should have explicit modifier.
+* Create one file (source and header) per class.
+* `else if` construction is allowed and recommended.
+* 'true ? foo : bar' construction is allowed and recommended for one-line assignment.
+* Any global pointer should be assign to `nullptr` after deletion and before
+  initialization. Exception: if object is deleted into class destructor.
+
+Comments
+--------
+
+Please do not hesitate to use comments inside source code (especially in non-obvious
+blocks). Comments also may use the following keywords:
+
+* **TODO** - indicates that some new code should be implemented here later. Please
+  note that usually these methods should be implemented before the next release.
+* **FIXME** - some dirty hacks and/or methods which should be done better.
+* **HACK** - hacks inside code which requires to avoid some restrictions and/or
+  which adds additional non-obvious optimizations.
+
+Do not use dots at the end of the comment line.
+
+Development
+-----------
+
+* Officially the latest libraries versions should be used. In addition it is
+  possible to add workarounds for all versions (usually by using preprocessor
+  directives); in this case patches should be placed to `packages` directory.
+* Build should not contain any warning.
+* Try to minimize message in Release build with logging disabled. It is highly
+  recommended to fix KDE/Qt specific warning if possible
+* Do not use dependency to KDE libraries if there are no any strictly necessary.
+  Exceptions are KNotification and KI18n libraries.
+* It is highly recommended to use submodules for third party libraries if possible.
+* The main branch is **development**. Changes in this branch may be merged to the
+  master one only if it is a 'stable' build.
+* For experimental features development new branch `feature-foo` creation is allowed
+  and recommended.
+* Experimental features should be added inside `BUILD_FUTURE` definition:
+
+  ```
+  #ifdef BUILD_FUTURE
+  someTestFunctionInside();
+  #endif /* BUILD_FUTURE */
+  ```
+
+* Any project specific build variable should be mentioned inside `version.h` as
+  well.
+* Recommended compiler is `clang`.
+
+HIG
+---
+
+The recommended HIG is [KDE one](https://techbase.kde.org/Projects/Usability/HIG).
+Avoid to paint interfaces inside plugin because QML and C++ parts may have different
+theming.
+
+Licensing
+---------
+
+All files should be licensed under GPLv3, the owner of the license should be the
+project (i.e. **awesome-widgets**). See **Tools** section for more details.
+
+Logging
+-------
+
+For logging please use [QLoggingCategory](http://doc.qt.io/qt-5/qloggingcategory.html).
+Available categories should be declared in `awdebug.*` files. The following log
+levels should be used:
+
+* **debug** (`qCDebug()`) - method arguments information. Please note that it
+  is recommended to logging all arguments in the one line.
+* **info** (`qCInfo()`) - additional information inside methods.
+* **warning** (`qCWarning()`) - not critical information, which may be caused by
+  mistakes in configuration for example.
+* **critical** (`qCCritical()`) - a critical error. After this error program may
+  be terminated.
+
+The empty log string (e.g. `qCDebug();`) is not allowed because the method names
+will be stripped by compiler with `Release` build type. To log class constructor
+and destructor use `__PRETTY_FUNCTION__` macro.
+
+Testing
+-------
+
+* Any changes should be tested by using `plasmawindowed` and `plasmashell` applications.
+  (It is also possible to use `plasmaengineexplorer` and `plasmoidviewer` in addition.)
+* Any test should be performed on real (not Virtual Machine) system.
+* Test builds should be:
+    1. `-DCMAKE_BUILD_TYPE=Debug`.
+    2. `-DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTING=ON`.
+    3. `-DCMAKE_BUILD_TYPE=Release`.
+* It is recommended to create addition test if possible.
+* Addition test functions should be declated and used only inside `BUILD_TESTING`
+  definition.
+
+Tools
+-----
+
+* For QString concatenation use `QString::arg` method.
+* Any source file should have license header:
+
+  ```

-* sysstat (*for notification*)
+
+* plasma-framework
 
 Optional dependencies

-* music player (amarok, mpd or qmmp)
+* hddtemp
+* smartmontools
+* music player (mpd or MPRIS supported)
 
 Make dependencies
 -----------------
-* automoc4
+
 * cmake
-* kdebase-runtime
+* extra-cmake-modules
 
 Installation
 ------------
+
 * download sources
 * install
 
         mkdir build && cd build
-        cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=`kde4-config --localprefix` ../
-        make && make install
-
-  Also you may install it to `/`:
-
-        mkdir build && cd build
-        cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ../
+        cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr ../
         make && sudo make install
 
+  **NOTE** on Plasma 5 it very likely requires `-DKDE_INSTALL_USE_QT_SYS_PATHS=ON` flag
