	Open OnDemand ("OOD") is a web-based service provided by GACRC which provides users an alternative and/or complementary method to access the HPC clusters. It helps computational researchers and students efficiently utilize remote computing resources by making them easy to access from any device, via a convenient web interface. Through Open OnDemand, graphical applications can be utilized on the cluster far more easily and smoothly than using X11 forwarding. It also helps computer center staff support a wide range of clients by simplifying the user interface and experience. A video introduction to ~~Kaltura~~ at UGA can be found '''[https://kaltura.uga.edu/media/t/1_u9d1xrpp/176125031 ~~here~~]'''.

If you would like to edit a file from within OOD, click the three-vertical-dots button to the right of a file name, and then click "Edit". This will open a new tab that allows you to edit and save changes to a file. The OOD file editor has a plethora of different syntax highlighting options.
