 # remindme_caldav
-## A Calendar Alerting Daemon
-
-## Purpose
-This script is a simple calendar alerting daemon written in Python. It monitors
-.ics files for changes and sends alerts based on the events' start times,
-recurrence rules, and alert triggers defined within these files. The main
-purpose of this script is to provide reminders or notifications about upcoming
-events.
-
-## How it Works
-The script works by parsing .ics files using the `icalendar` library, which
-converts them into a Python dictionary format for easier manipulation. It then
-processes each event and calculates when the next alert should be triggered
-based on the event's start time, recurrence rules, and alert triggers. If an
-alert is due to trigger, it sends a notification via email or XMPP (an instant
-messaging protocol).
-
-The script also monitors for changes in the directory containing .ics files
-using the `watchdog` library. When a file is modified, created, or deleted, it
-updates its internal list of events accordingly.
-
-## How to Use It
-This script should be used with a calendar syncing service such as vdirsyncer.
-vdirsyncer can be scheduled using cron to sync regularly from the CalDav
-server.
-
-To use this script, you need Python 3 installed on your system. You can install
-the required libraries by running:
-
-```bash
-pip install -r requirements.txt
-```
-
-You also need a .toml configuration file with the following structure:
-```toml
-[app]
-calendar_dir = "/path/to/your/ics/files"
-email_address = "your-email@example.com"
-smtp_server = "smtp.example.com"
-smtp_port = 587
-smtp_username = "your-username"
-smtp_password = "your-password"
-...
-```
-The config file is passed to the script with the `--config` argument.
-
-You can then run the script with:
-```bash
-python3 remindme_caldav.py --config /path/to/your/config.toml
-```
-
-## Installation
-A Makefile and systemd service file is also included for Debian/Ubuntu based
-systems. Make sure to modify the config file in the source directory before
-installation. Also, please ensure that the calendar_dir exists and syncing
-from a CalDav server before running the script.
-
-This Makefile does the following:
-  - install: Installs Python 3.11, creates a virtual environment in
-    /opt/remindme_caldav/.venv, installs dependencies from requirements.txt
-    into this virtual environment, copies the script to /opt/remindme_caldav/,
-    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.
-
-## 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.
 
+A simple script to send alerts/reminders for caldav events.
