+    tracing is set basd on the environment variable RUST_LOG=xxx, depending on the amount of logs to show
+        ERROR > WARN > INFO > DEBUG > TRACE
+    eg. RUST_LOG=info will show info, warn, and error logs
+        RUST_LOG="theseus=trace" will show *all* messages but from theseus only (and not dependencies using similar crates)
+        RUST_LOG="theseus=trace" will show *all* messages but from theseus only (and not dependencies using similar crates)
+
+    Error messages returned to Tauri will display as traced error logs if they return an error.
+    This will also include an attached span trace if the error is from a tracing error, and the level is set to info, debug, or trace
+
+    on unix:
+        RUST_LOG="theseus=trace" {run command}
+
+    The default is theseus=show, meaning only logs from theseus will be displayed, and at the info or higher level.
