 # Calc
 
-Calc is a macOS SwiftUI calculator app with:
-
-- arbitrary-precision decimal calculations
-- mouse-friendly circular controls
-- keyboard input
-- native copy support for the current display
-- parentheses and exponent support
-- standard scientific functions and constants
-- reusable calculation history
-- a custom app icon
+Calc is a macOS calculator app with arbitrary-precision decimal math, scientific functions, keyboard input, native copy support, and calculation history.
 
 ## Requirements
 
 - macOS with Xcode installed
 - Xcode command line tools available
 
-## Common CLI commands
-
-Use the helper scripts from the repo root:

 ## Scientific input
 
-Basic arithmetic uses arbitrary-precision decimal math, so large integers and decimal expressions stay exact instead of falling back to `Double` precision. The display still uses grouped digits for readable values and switches to scientific notation for very large results.
-
-Supported scientific functions:
-
-- `sin`, `cos`, `tan`
-- `asin`, `acos`, `atan`
-- `ln`, `log`, `sqrt`
-- `abs`, `exp`
-- `pi`, `e`
-
-Text input supports the same keywords from the keyboard. For example:
-
-```text
-ln(e)
-sin(pi/2)
-sqrt(16)
-log(1000)
-```

-## Build a Release app
-
-```bash
-./build.sh
-```
-
-## Run a Debug build
-
-Build and launch the Debug app:
-
-```bash
-./debug.sh
-```
-
-Build without launching:
-
-```bash
-./debug.sh --build-only
-```
-
-Run the built binary directly in the terminal:
-
-```bash
-./debug.sh --exec
-```
-
-## Run tests
-
-```bash
-./test.sh
-```
-
-## Install the app
-
-```bash
-./install.sh
-```
-
-Useful install options:
-
-```bash
-./install.sh --system
-./install.sh --user
-./install.sh --install-dir /custom/path
-```
-
-## Raw Xcode commands
-
-If you want to bypass the helper scripts, these are the equivalent commands. The `GIT_CONFIG_*` prefix mirrors the helper scripts so Swift package resolution still works on systems that use `safe.bareRepository=explicit`.
