 GEOS is a simulation framework focused solving tightly-coupled multi-physics problems with an initial emphasis subsurface reservoir applications.
 Currently GEOS actively supports implementations for studying carbon sequestration, geothermal energy, hydrogen storage, and similar subsurface applications.
 The unique aspect of GEOS that differentiates it from existing reservoir simulators is the ability to provide tightly-coupled compositional flow, poromechanics, faults and fractures slip, and thermal effects, etc.
-The GEOS repository is hosted on GitHub [@GEOS:2024], and extensive documentation is available on Read the Docs [@GEOS_RTD].
+Extensive documentation is available on Read the Docs [@GEOS_RTD].
 Note that the version of GEOS described here should be considered a separate work form the previous incarnation of GEOS referred to in [@Settgast:2017].
