-# Spatial Data Science across Languages workshops
+# Spatial Data Science across Languages Community
 
-The ‘Spatial Data Science across Languages’ (SDSL) workshops provide a space for bridging the 
-communities and establishing cross-language interaction between developers and users.
-SDSL seeks to bring together the communities from the common and emerging programming languages used
-for data science such as R, Python and Julia, to discuss interoperability, methodological developments, 
-and shared challenges such as interfacing upstream libraries (including GDAL, GEOS, and PROJ), packaging
-and distributing software, and managing user and developer communities.

-The SDSL workshops aim to identify commonalities and differences between spatial data science languages, 
-to bridge language barriers and to bring the different communities together to discuss, cooperate, and
-synchronise the development efforts. 
+## Annual Workshop
 
+Our main activity since 2023 has been annual workshops which provide a space for
+bridging the various programming-language communities and establishing
+cross-language interaction between developers and users.
