+## Guidelines
+* Use generic formats
+* Where possible, use QVector over QList: 
+http://lists.qt-project.org/pipermail/development/2017-March/029040.html
+
+## Versioning
+
+#### Major version
+Changed infrequently and almost entirely out of foppery and whim.
+
+#### Minor version
+Milestone of multiple features.
+
+#### Revision
+Major bugfixes and each new feature should get a revision.
+
+### Branching
+* master - main branch, should be kept up-to-date, and have only working code
+* next - next stable release preparation, mostly for bugfixes
+* development - development branch, anything goes there
+
+### Folder structure
+
+  folder       | description
+  ------       | -----------
+/src           | source code
+/src/widgets   | subclassed Qt widgets
+/src/formats   | file format parsing (toml, xbel)
+/src/forms     | Qt UI forms and classes
+/src/webengine | QWebEngine subclasses
+/test          | test run location, mainly for QtCreator

+## clazy
+You can use [clazy](https://github.com/KDE/clazy) to check Qt semantics. 
+Requires clang.
+
+To set check levels, set the CLAZY_CHECKS environment variable to 'level0,level1', etc.
+
+### Setting up in QtCreator
+The simplest way to set it up is to use _clazy_ instead of _clang_.
+
+1. Go to Tools » Options » Build & Run » Compilers
+2. Clone the clang compiler of your choice
+3. Set _Compiler path_ to _/usr/bin/clazy_
+
+This will update the qbs profile that QtCreator uses.
+
+### Reducing clazy noise
+If you want to suppress warnings from headers of Qt or 3rd party code, include
+them with -isystem instead of -I. To do this, you have to
+[modify your Qt profile](clazy-sysincludes) like this:
+
+Find the profile's search path:
+```sh
+$ qbs config --list profiles.qt562.preferences
+profiles.qt562.preferences.qbsSearchPaths: "/home/someone/.config/QtProject/qbs/1.9.0/profiles/qt562"
+```
+
+Replace cpp.includePaths with cpp.systemIncludePaths in the Qt modules of that
+profile:
+
+```sh
+$ find /home/someone/.config/QtProject/qbs/1.9.0/profiles/qt562/modules/Qt/ -name '*.qbs' | xargs -n1 sed -i s/cpp\.includePaths/cpp.systemIncludePaths/
+```
