+# Org2Ics - Bidirectional Org/iCalendar Converter
+
+A C# console application that provides bidirectional conversion between .org diary files and .ics (iCalendar) format.
+
+## Description
+
+This tool converts between .org files containing diary entries and iCalendar (.ics) files. It supports:
+- **Org to ICS**: Convert diary entries to all-day calendar events named "Chronolog"
+- **ICS to Org**: Convert calendar events back to org diary format with proper date headers
+
+## Features
+
+- **Bidirectional conversion** between .org and .ics formats
+- **Auto-detection** of input file format based on file extension
+- **Org to ICS conversion**:
+  - Parses .org files with level 3 headings (***) containing dates in YYYY-MM-DD format
+  - Extracts diary content for each date entry
+  - Creates all-day events with the title "Chronolog"
+  - Includes diary content as event descriptions
+- **ICS to Org conversion**:
+  - Parses standard .ics calendar files
+  - Extracts event dates and descriptions
+  - Organizes entries by year and month
+  - Creates proper org-mode structure with level 3 date headers
+- **Proper character escaping** for both formats
+- **Round-trip compatibility** for seamless conversion between formats
+
+## Usage
+
+```bash
+dotnet run <input.org|input.ics> [output.ics|output.org]
+```
+
+### Parameters
+
+- `input.org|input.ics`: Path to the input file (required)
+  - `.org` files will be converted to `.ics` format
+  - `.ics` files will be converted to `.org` format
+- `output.ics|output.org`: Path to the output file (optional, auto-determined if not specified)
+
+### Examples
+
+```bash
+# Convert diary.org to diary.ics
+dotnet run diary.org
+
+# Convert calendar.ics to calendar.org
+dotnet run calendar.ics
+
+# Specify custom output filename
+dotnet run diary.org my-calendar.ics
+dotnet run calendar.ics my-diary.org
+
+# Round-trip conversion
+dotnet run diary.org calendar.ics
+dotnet run calendar.ics diary-restored.org
+```
+
+## File Format Support
+
+### Org File Format (.org → .ics)
+
+The converter expects .org files with the following structure:
+
+```org
+* My Diary
+
+** Month Section
+
+*** 2025-01-15
+
+This is the diary content for January 15th, 2025.
+It can span multiple lines and paragraphs.
+
+*** 2025-01-16
+
+Another diary entry for the next day.
+
+** Another Section
+
+*** 2025-02-01
+
+February entry content here.
+```
+
+**Requirements:**
+- Level 3 headings (starting with `***`) must contain dates in `YYYY-MM-DD` format
+- Everything after a date heading until the next heading becomes the diary content for that date
+- Non-date headings are ignored
+
+### ICS File Format (.ics → .org)
+
+The converter can parse standard iCalendar files and extracts:
+- Event dates (both all-day and timed events)
+- Event descriptions or summaries as diary content
+- Events are organized chronologically and grouped by month
+
+**Supported:**
+- `DTSTART;VALUE=DATE:` (all-day events)
+- `DTSTART:` (timed events - date portion used)
+- `DESCRIPTION:` field content
+- `SUMMARY:` field content (when no description available)
+- Proper unescaping of iCalendar text formatting
+
+## Output Formats
+
+### Generated .ics Files (from .org)
+- Standard iCalendar format (RFC 5545 compliant)
+- All-day events spanning from the diary date to the next day
+- Event title: "Chronolog"
+- Event description: The diary content for that date
+- Unique identifiers for each event
+
+### Generated .org Files (from .ics)
+- Proper org-mode structure with hierarchical headings
+- Level 1: "Diary" (root heading)
+- Level 2: Month and year groupings (e.g., "January 2025")
+- Level 3: Individual date entries (e.g., "*** 2025-01-15")
+- Content: Event descriptions properly formatted for org-mode
+
+## Building
+
+```bash
+dotnet build
+```
+
+## Requirements
+
+- .NET 8.0 or higher
+- No additional dependencies required
