To help you install the `haste-it` binaries efficiently on various architectures, I'll provide you with a README guide that includes bash one-liners for installation. Additionally, I'll include a simple bash script for automatic installation and setting up the environment variable for the Hastebin server URL.

# Haste-It Installation Guide

This guide provides instructions for installing the `haste-it` binary on various systems based on the architecture.

## Installation

Before installing, ensure that the binary for your architecture has been built and is located in the `dist` directory.

Run the following command to install the `haste-it` binary:

```bash
bash install.sh
```

This script will automatically detect your system's architecture, choose the correct binary from the `dist` directory, and install it.

## Configuration

After installation, set the environment variable for your Hastebin server by adding the following to your `.bashrc`, `.zshrc`, or equivalent shell configuration file:

```bash
export HASTEBIN_URL="https://your-hastebin-server.com"
```

Replace `https://your-hastebin-server.com` with the URL of your Hastebin server.

## Usage

After installation and configuration, you can use `haste-it` by simply typing:

```bash
haste-it [file]
```

If no file is specified, `haste-it` will read from standard input.
```

### 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`.

## Instructions for Use

    Ensure that install.sh has execute permissions:

```bash
chmod +x install.sh
```
Run the script with sufficient privileges (as it installs to /usr/local/bin):

```bash
sudo ./install.sh
```
Set the environment variable as described in the README.
