-### General rule
 
-- following the approach of presenting the __respective ArcGIS solutions__ to the sample R examples
-    - consequently, providing the links to the esri resourses seems quite meaningfull

+## Some basic text formatting rules for keeping the document consistent.
 
 - formatting with __bold__, in the following cases:
-    - package name (e.g __sf__)
-    - operation (e.g __spatial subsetting__)
     - dataset name (e.g __parking spots in the canton of Zurich__)
 
 - formatting with _italics_, in the following cases:
-    - function name (e.g _st_buffer_)
+    - referring to a tool (e.g `Select By Attributes`) 
+    - operation (e.g __spatial subsetting__)
+
 
 - formatting with this `format`, in the following cases:
-    - referring to a tool (e.g `Select By Attributes`) 
+    - package name (e.g __sf__)
