-All packages released will be labeled with date of release in format RRRR-MM-DD and released as often as

+# Installation
+
+CMake project files in main and data repositories are integrated and when invoked during compilation,
+produce output files to be installed. As of 0.1.2-alpha, the generated files are different from source
+files. Consequently, running the game with data files directly from this source repository is not supported.
+Please see the [INSTALL.md](https://github.com/colobot/colobot/blob/master/INSTALL.md) instructions
+in main repository for details.
+
+Some details of how data file translation is achieved can be found in
+[README.i18n.md](https://github.com/colobot/colobot-data/blob/master/README.i18n.md) file.
