## Building
**Read the developer handbook for a [complete build walkthrough](http://musescore.org/en/developers-handbook/compilation) and a list of dependencies.**
### Getting sources
If using git to download repo of entire code history, type:
git clone https://github.com/musescore/MuseScore.git
cd MuseScore
Else can just download the latest source release tarball from https://github.com/musescore/MuseScore/releases, and then from your download directory type:
tar xzf MuseScore-x.x.x.tar.gz
cd MuseScore-x.x.x
### Release Build
To compile MuseScore, type:
make release
If something goes wrong, then remove the whole build subdirectory with `make clean` and start new with `make release`.
### Running
To start MuseScore, type:
./build.release/mscore/mscore
The Start Center window will appear on every invocation, until you disable that setting via the "Preferences" dialog.
### Installing
To install to default prefix using root user, type:
sudo make install
### Debug Build
A debug version can be built by doing `make debug` instead of `make release`.
To run the debug version, type:
./build.debug/mscore/mscore
### Testing
See [mtest/README.md](/mtest/README.md) or https://musescore.org/en/developers-handbook/testing for instructions on how to run the test suite.
