##### Older changes



Changes before this repository's creation can be found on [the project's website](http://www.codersnotes.com/programs/sleepy).



### Building



#### Prerequisites



* Visual C++ 2010 or newer

* [CMake](https://cmake.org/) (for Dr. MinGW)

* [7-Zip](http://www.7-zip.org/) (for unpacking MinGW)

* [InnoSetup 5](http://www.jrsoftware.org/isinfo.php) (for building an installer)



#### Instructions



Third party dependencies are registered using git submodules, so you will need to either clone with the `--recursive` flag, or run `git submodule update --init` after cloning.



The `build.cmd` batch file will attempt to build Very Sleepy and its dependencies.



Alternatively, you can build Dr. MinGW using the `thirdparty/drmingw_build_mingw.cmd` batch file, then use the Visual Studio solution file (`sleepy.sln`) to build everything else.



### Contributing



If you'd like to contribute a patch, please [open a pull request](https://github.com/VerySleepy/verysleepy/pulls). I'll try to review and merge it as soon as my time will allow.



Bug reports and feature requests are welcome as well -- please file them as [GitHub issues](https://github.com/VerySleepy/verysleepy/issues).
