# OOoLilyPond OOoLilyPond (OLy) is a LibreOffice/OpenOffice extension to include LilyPond music fragments in text documents. ## Installation Being a [LibreOffice]/[OpenOffice] extension, you need a version of LibreOffice / OpenOffice installed on your computer, first. And the music engraving software [LilyPond] must be installed on your system. Then just download the latest OLy release from the [download] page. The extension can be installed either by opening it with LibreOffice or by following these steps in the menu: *Extras > Extension Manager… > Add…* and then choosing the downloaded extension file (.oxt). Your toolbars in Writer, Impress and Draw should now have a new "OLy" button which launches the extension. ## Usage [LilyPond] is powerful musical typesetting software that compiles given source code into graphical output, just like LaTeX does with mathematical formulas. OOoLilyPond enables you to enter LilyPond code from within your Office document. Both the resulting image and its source code will be embedded within the document. No need to keep any additional files other than the Writer/Draw/Impress document itself. To create a new OLy object, just click the "OLy" button and an editor window will open.
