-A high-performance **k32-only**, Chia (XCH) plotter supporting in-RAM and disk-based plotting.
+A high-performance **k32-only**, Chia (XCH) plotter.
+
+Bladebit supports 3 plotting modes:
+ - Fully In-RAM (no drives required), CPU-based mode.
+ - GPU (CUDA-based) mode. Both fully in-RAM or disk-hybrid mode.
+ - Disk-based mode
+
+## Usage
+Run `bladebit --help` to see general help. For command-specific help, use `bladebit help <command_name>`.
+
+## Requirements
+
+**CUDA**
+
+An NVIDIA GPU is required for this mode. This mode is exposed via the `cudaplot` command in a separate executable "bladebit_cuda". This mode has mainly been tested on consumer cards from the **10xx** series and up. 
+
+| Mode                           | OS             | DRAM | VRAM | CUDA capability 
+|--------------------------------|----------------|------|------|----------------
+| In-RAM                         | Linux, Windows | 256G | 8G   | 5.2 and up
+| Disk-hybrid 128G               | Linux, Windows | 128G | 8G   | 5.2 and up
+| Disk-hybrid 16G (WIP)          | Linux          | 16G  | 8G   | 5.2 and up
+
+> *NOTE: 16G mode currently a work in progress and at this stage it only works in Linux and direct I/O is unavailable in this mode.*
+
+
+**CPU RAM-Only**
+
+Available on Linux, Windows and macOS.
+Requires at least **416G** of system DRAM.
+
+
+**Disk**
+
+Available on Linux, Windows and macOS.
+
+A minimum of **4 GiB of RAM** is required, with lower bucket counts requiring up to 12 GiB of RAM. Roughly **480 GiB of disk space** is required in the default mode, or around **390 GiB of disk space** with `--alternate` mode enabled.
+
+The exact amounts of RAM and disk space required may vary slightly depending on the system's page size and the target disk file system block size (block-alignment is required for direct I/O).
+
+SSDs are highly recommended for disk-based plotting.
+
+
+## Compressed Plots
+
+Compressed plots are supported in CUDA mode and in RAM-only mode. CPU Disk-based mode does **NOT** currently support compressed plots.
+
+Compressed plots are currently supported for compression levels from **C1** to **C7**. Note that bladebit compression levels are not compatible with other plotter compression levels. These compression levels are based on the *number of bits dropped from an entry excluding the minimum bits required to fully drop a table*. At `k=32` a the first table is fully excluded from the plot at 16 bits dropped.
+
+> *NOTE: Although higher compression levels are available, support for farming them has not been currently implemented and are therefore disabled. They will be implemented in the future.*
+
+Compression levels are currently roughly equivalent to the following plot sizes.
+
+| Compression Level | Plot Size
+|-------------------|-------------
+| C1                | 87.5 GiB
+| C2                | 86.0 GiB
+| C3                | 84.4 GiB
+| C4                | 82.8 GiB
+| C5                | 81.2 GiB
+| C6                | 79.6 GiB
+| C7                | 78.0 GiB
+
+These might be optimized in the future with further compression optimizations.
