+    copies the config file to /etc/remindme_caldav and sets up the systemd
+    service file. It also sets up the logging dir in /opt/remindme_caldav/logs.
 
   - uninstall: Stops and disables the systemd service, removes the installation
     directory (/opt/remindme_caldav/), and deletes the systemd service file.
 
-  - clean: Deactivates the virtual environment.
+## Logging
+The script uses Python's built-in logging module to handle logging. The
+setup_logging(log_location) function sets up basic configuration for the
+logger, including the log file location and format. 
 
+Log levels are used to categorize logs based on their severity: DEBUG, INFO,
+WARNING, ERROR, CRITICAL. By default, the log level is set to INFO. This can
+be modified by passing a --loglevel argument when running the script.
+
+The setup_log_location(logdir) function sets up the locations for three types
+of logs: log, status, and alert_history. 
+
+ - Log Location: This is where script logs are stored. These logs contain
+   information about the general operation of the script, such as when it
+   starts or stops, what files it's processing, errors etc. The logdir argument
+   specifies the directory where these log files will be created. 
+
+ - Status Location: This file contains information about the current state of
+   each event being monitored by the script. It includes details such as the
+   current time, the name of the event, its recurrence dates, and when the
+   next alert will be triggered. The purpose of this file is to provide a
+   real-time status update on what's happening in the script.
+
+ - Alert History Location: This file logs all alerts that have been sent out
+   by the script. It includes details such as the timestamp when the alert was
+   triggered, and the definition time of the alert. The purpose of this file
+   is to keep a record of all alerts that have been sent.
