 ### Samples
+All updated to work with dotnetcore 3.1
 
-*TODO*
+1. update the appsettings.json file (note: enter the host without protocol prefix, and set the use of ssl)
+2. Alternative 1, create an appsettings.Development.json file and optionally other env settings files, which you don't want source controlled.
+Then run the sample project with `DOTNETCORE_ENVIRONMENT=Development dotnet run`
+3. Alernative 2, use env variables instead of appsetting values when starting the sample project. Example:
+`OdooConnection__Host=my.odoohost.com OdooConnection__Password=mypassword dotnet run`
+
+The above commands are for UNIX, if you are on windows, command-line env vars are set like `set ENV_VAR=value && dotnet run`
