@@ -14,155 +14,3 @@ A native desktop application for calculating dice statistics for tabletop RPGs.
 - **Standard Dice Support**: d4, d6, d8, d10, d12, d20, d100
 - **Custom Dice**: Use `dx` to define custom dice (e.g., `d24`, `d30`)
 - **Calculator-Style Interface**: Familiar button layout resembling a traditional calculator
-
-## Building
-
-### Prerequisites
-
-- Go 1.25.7 or later
-- [Fyne GUI library](https://fyne.io/) (automatically fetched by `go mod`)
-
-### Build Instructions
-
-```bash
-cd desktop_dice_statistics_calculator
-go build -o dice_calculator
-```
-
-This creates an executable named `dice_calculator` in the current directory.
-
-### Running
-
-```bash
-./dice_calculator
-```
-
-On Windows, use:
-```bash
-dice_calculator.exe
-```
-
-## Application Structure
-
-### main.go
-The main application file containing all UI logic:
-- Window setup and layout management
-- Dice control bar with quick-access buttons (d4, d6, d8, d10, d12, d20, d100, dx, H, L)
-- Calculator-style number pad and operation buttons
-- Input field for dice expressions
-- Output display for results
-- Event handlers for button clicks
-
-### calculations.go
-The calculation engine containing all dice logic:
-- **CalculateDice()**: Main entry point for evaluating dice expressions
-- **expandDiceNotations()**: Parses and rolls dice notation (e.g., `2d20H`)
-- **rollDiceSet()**: Rolls a specified number of dice with a given number of sides
-- **evaluateMathExpression()**: Evaluates mathematical expressions with proper operator precedence
-- **ExpressionParser**: Recursive descent parser handling +, -, *, /, and parentheses
-
-## Usage Examples
-
-### Basic Dice Rolls
-- `d20` - Roll a single d20
-- `2d6` - Roll two d6s and sum them
-- `3d4` - Roll three d4s and sum them
-
-### With Modifiers
-- `2d20H` - Roll two d20s, take the highest (advantage in D&D 5e)
-- `2d20L` - Roll two d20s, take the lowest (disadvantage in D&D 5e)
-- `4d6L` - Roll four d6s, take the lowest (typical stat rolling method)
-
-### With Arithmetic
-- `2d6 + 5` - Roll 2d6 and add 5
-- `3d6 + 2d4 + 3` - Multiple dice and modifiers
-- `2d6 * 2` - Roll 2d6 and multiply by 2
-- `(2d6 + 1) * 3` - Using parentheses for complex calculations
-
-### Custom Dice
-- `d24` - Roll a 24-sided die
-- `3d30` - Roll three 30-sided dice
-- `d100` - Roll a percentile die
-

-## Supported Operations
-
-### Dice Notation
-- `[count]d[sides]` - Standard dice notation (count defaults to 1)
-- `H` - Take highest result (when count > 1)
-- `L` - Take lowest result (when count > 1)
-
-### Arithmetic Operations
-- `+` Addition
-- `-` Subtraction
-- `*` Multiplication
-- `/` Division (integer division)
-- `()` Parentheses for grouping
-
-### Operator Precedence
-1. Parentheses
-2. Unary minus (e.g., `-5`)
-3. Multiplication and Division (left-to-right)
-4. Addition and Subtraction (left-to-right)
-
-## Error Handling
-
-The calculator provides error messages for:
-- Invalid dice notation (e.g., `d0`, `0d6`)
-- Division by zero
-- Malformed expressions
-- Unexpected characters
-
-When an error occurs, it displays in the result field with an "Error: " prefix.
-
-## Dependencies
-
-- `fyne.io/fyne/v2` - Cross-platform GUI library
-- Go standard library (math/rand, regexp, strconv, strings, time, etc.)
-
-## Cross-Platform Support
-
-This application is built with Fyne, which supports:
-- **Linux** - All major distributions
-- **Windows** - Windows 7 and later
-- **macOS** - (Can be built, but not tested in this project scope)
-
-To build for a different platform, use Go's cross-compilation flags:
-```bash
-GOOS=windows GOARCH=amd64 go build
-GOOS=linux GOARCH=amd64 go build
-```
-
-## Future Enhancement Ideas
-
-- History of recent rolls
-- Statistics display (average, min, max for dice rolls)
-- Save/load custom dice definitions
-- Keyboard shortcuts for common operations
-- Dark/light theme support
-- Sound effects for dice rolls
