-# Eink
+# EInk
 
-**TODO: Add description**
+An Elixir library for driving E-Ink (Electronic Paper Display) screens. This library provides high-level abstractions for controlling E-Ink displays through SPI communication, with built-in support for multiple display controllers and integrated image processing capabilities.
+
+## Features
+
+- **Multiple Controller Support**: Built-in drivers for UC8179 and UC8276 controllers
+- **Full & Partial Refresh**: Support for both full screen updates and fast partial refresh modes
+- **Integrated Image Processing**: Powered by a Rust NIF for high-performance dithering, resizing, and grayscale conversion
+- **Hardware Abstraction**: Clean driver interface for easy extension to additional controllers
+- **SPI Communication**: Efficient communication using [Elixir Circuits](https://github.com/elixir-circuits) (Circuits.SPI and Circuits.GPIO)
+
+## Supported Hardware
+
+### Display Controllers
+
+- **UC8179**: Typically found in larger displays (7.5", 5.83")
+  - Resolution: 800x600
+  - Partial refresh support
+  
+- **UC8276**: Common in medium-sized displays (4.2")
+  - Resolution: 400x300
+  - Partial refresh support
+
+### Compatible Display Brands
+
+This library works with E-Ink displays from manufacturers using the supported controllers, including:
+- Waveshare e-Paper displays
+- GoodDisplay e-Paper modules
+- Other displays using UC8179 or UC8276 controllers
+
+## Architecture
+
+EInk uses a hybrid architecture combining Elixir and Rust:
+
+- **Elixir Drivers** (`lib/eink/driver/`): Handle SPI communication, display initialization, and command sequences using [Elixir Circuits](https://github.com/elixir-circuits)
+- **Rust NIF** (via `dither` dependency): Provides high-performance image processing (dithering, resizing, grayscale conversion)
+
+The Rust NIF is **precompiled** using `rustler_precompiled`, so you don't need the Rust toolchain installed. The correct binary for your platform is automatically downloaded during compilation.
 
 ## Installation
 
-If [available in Hex](https://hex.pm/docs/publish), the package can be installed
-by adding `eink` to your list of dependencies in `mix.exs`:

-Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
-and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
-be found at <https://hexdocs.pm/eink>.
+## Usage
+
+### Basic Example
+
+```elixir
+# Initialize the display driver with hardware configuration
+{:ok, display} = EInk.new(EInk.Driver.UC8276, [
+  spi_device: "spidev0.0",
+  dc_pin: 25,      # Data/Command pin
+  reset_pin: 17,   # Reset pin
+  busy_pin: 24     # Busy signal pin
+])
+
+# Clear the screen to white
+EInk.clear(display, :white)
+
+# Load and process an image
+{:ok, image} = Dither.load("path/to/image.png")
+
+# Get display capabilities
+%{width: width, height: height} = EInk.Driver.UC8276.capabilities()
+
+# Resize image to match display resolution
+{:ok, image} = Dither.resize(image, width, height)
+
+# Convert to grayscale
+{:ok, image} = Dither.grayscale(image)
+
+# Apply dithering for 1-bit black and white display
+{:ok, image} = Dither.dither(image, algorithm: :sierra, bit_depth: 1)
+
+# Convert to raw binary format
+{:ok, raw_data} = Dither.to_raw(image)
+
+# Draw to the display with full refresh
+EInk.draw(display, raw_data, refresh_type: :full)
+```
+
+### Partial Refresh
+
+For faster updates on supported displays:
+
+```elixir
+# Draw with partial refresh (faster, but may have ghosting)
+EInk.draw(display, raw_data, refresh_type: :partial)
+```
+
+### Dithering Algorithms
+
+The `Dither` library supports multiple algorithms:
+
+- `:floyd_steinberg` - Classic error diffusion (good general-purpose)
+- `:sierra` - Sierra-3 algorithm (default, good quality)
+- `:atkinson` - Atkinson dithering (high contrast)
+- `:stucki` - Stucki algorithm (smooth gradients)
+- `:burkes` - Burkes algorithm
+- `:jarvis` - Jarvis-Judice-Ninke algorithm
+
+Example:
+
+```elixir
+{:ok, dithered} = Dither.dither(image, algorithm: :floyd_steinberg, bit_depth: 1)
+```
+
+## Hardware Configuration
+
+### Raspberry Pi Example
+
+When connecting an E-Ink display to a Raspberry Pi:
+
+1. **Enable SPI**: Run `sudo raspi-config` and enable SPI under Interface Options
+2. **Connect the display**:
+   - VCC → 3.3V
+   - GND → Ground
+   - DIN → MOSI (GPIO 10)
+   - CLK → SCLK (GPIO 11)
+   - CS → CE0 (GPIO 8)
+   - DC → GPIO 25 (configurable)
+   - RST → GPIO 17 (configurable)
+   - BUSY → GPIO 24 (configurable)
+
+3. **Configure in your code**:
+
+```elixir
+{:ok, display} = EInk.new(EInk.Driver.UC8276, [
+  spi_device: "spidev0.0",  # Use spidev0.1 for CE1
+  dc_pin: 25,
+  reset_pin: 17,
+  busy_pin: 24
+])
+```
+
+## Display Drivers
+
+### Creating a Custom Driver
+
+To support additional display controllers, implement the `EInk.Driver` behavior:
+
+```elixir
+defmodule EInk.Driver.MyController do
+  use EInk.Driver, 
+    width: 640, 
+    height: 384, 
+    palette: :bw, 
+    partial_refresh: true
+
+  @impl EInk.Driver
+  def new(opts), do: {:ok, state}
+
+  @impl EInk.Driver
+  def reset(state), do: {:ok, state}
+
+  @impl EInk.Driver
+  def init(state, _opts), do: {:ok, state}
+
+  @impl EInk.Driver
+  def draw(state, image, opts), do: {:ok, state}
+
+  @impl EInk.Driver
+  def sleep(state), do: {:ok, state}
+
+  @impl EInk.Driver
+  def wake(state), do: {:ok, state}
+end
+```
+
+## Dependencies
