 Functions that start other functions(or processes) should log the start & end events themselves, and delegate the rest of the logging to the called function.

+- Logging level standards
+
+    - Trace level
+
+    Simple and straightforward verbose messages
+
+    ```go
+    log.Trace("this is a trace message")
+    ```
+
+    - Debug level
+
+    Logging should report the caller
+
+    ```go
+    log.SetReportCaller(true)
+    log.Debug("function called")
+    ```
+
+    - Info level
+
+    Meaningful messages that the end user should receive.
+
+    ```go
+    log.Info("finished the process")
+    ```
+
+    - Warn level
+
+    Warn level should use `.WithError(err)` is there is an error that can be handled or should be ignored.
+
+    ```go
+    log.WithError(err).Warn("encountered an error when doing something")
+    ```
+
+    - Error level
+
+    Error level should use `.WithError(err)` is there is an error that cannot be ignored.
+
+    ```go
+    log.WithError(err).Error("encountered an error when doing something")
+    ```
