### Installation Script (`install.sh`)

Here's a simple bash script to automate the installation process. This script will detect the architecture, find the appropriate binary in the `dist` directory, and install it to `/usr/local/bin`.

```bash
#!/bin/bash

# Define the installation directory and binary name
INSTALL_DIR="/usr/local/bin"
BINARY_NAME="haste-it"

# Define supported architectures and corresponding binaries
declare -A binaries
binaries["linux/amd64"]="haste-it_linux_amd64"
binaries["linux/arm64"]="haste-it_linux_arm64"
binaries["linux/arm/v7"]="haste-it_linux_arm"
binaries["darwin/amd64"]="haste-it_darwin_amd64"
binaries["darwin/arm64"]="haste-it_darwin_arm64"

# Detect the OS and architecture
OS="$(uname -s | tr '[:upper:]' '[:lower:]')"
ARCH="$(uname -m)"

case $ARCH in
    x86_64)
        ARCH="amd64"
        ;;
    arm64)
        ARCH="arm64"
        ;;
    aarch64)
        ARCH="arm64"
        ;;
    arm*)
        ARCH="arm/v7"
        ;;
esac

# Construct the key for finding the binary
KEY="${OS}/${ARCH}"

# Check if the binary exists for this architecture
if [[ -z "${binaries[$KEY]}" ]]; then
    echo "No pre-built binary for your system architecture ($KEY)."
    exit 1
fi

# Install the binary
BINARY_PATH="dist/${binaries[$KEY]}"
if [[ -f "$BINARY_PATH" ]]; then
    sudo cp "$BINARY_PATH" "$INSTALL_DIR/$BINARY_NAME"
    sudo chmod +x "$INSTALL_DIR/$BINARY_NAME"
    echo "Installed $BINARY_NAME to $INSTALL_DIR"
else
    echo "Binary file not found: $BINARY_PATH"
    exit 1
fi
