 Once the TSP is running, you can experiment with this example Node program. It illustrates the basics of how
 to use the Tenant Security Client (TSC) SDK to log security events. The example code shows two scenarios:
 
--   logging a login security event with additional metadata
--   logging an admin create security event with minimal metadata
+- logging a login security event with additional metadata
+- logging an admin create security event with minimal metadata
 
 To run the example, you will need to have Node installed on your computer. Try a `node -v` to see
 what version you are using. We tested the example code using v10.22.0 and v12.0.0.
