     """
-    Code generation system developed to support domain-specific languages
-    (DSLs) for finite element, finite volume and finite difference codes.
-    Notably, it is used in the LFRic Project from the UK Met Office, and
-    it also supports the GOcean (2D, finite difference) DSL.
+    A source-to-source Fortran compiler designed to programmatically optimise,
+    parallelise and instrument HPC applications (written in Fortran) via user-
+    provided transformation scripts. Additionally, PSyclone supports the
+    development of kernel-based, Fortran-embedded DSLs and is used in the UK
+    Met Office's next-generation modelling system, LFRic.
