-## Introduction
+# Introduction
 * This is an ESP32 Arduino/IDF library for HUB75 / HUB75E RGB LED panels. 
 * This library 'out of the box' (mostly) supports HUB75 panels where TWO rows/lines are updated in parallel... referred to as 'two scan' panels within this library's documentation. 
 * 'Four scan' panels are also supported - but please refer to the Four Scan Panel example.
 * The library uses the DMA functionality provided by the ESP32's 'LCD Mode' for faster output.
 
-### Features
+## Features
 -  **Low CPU overhead** - Pixel data is sent directly with the use of hardware-backed DMA, no CPU involvement
 -  **Fast** - Updating pixel data involves only bit-wise logic over DMA buffer memory, no pins manipulation or blocking IO
 -  **Full screen BCM** - Library utilizes [binary-code modulation](http://www.batsocks.co.uk/readme/art_bcm_5.htm) to render pixel color depth / brightness over the entire matrix to give reasonable colour depth

 "*What's the price for those features?*" - It's [memory](/doc/memcalc.md), you pay it all by precious MCU's internal memory (SRAM) for the DMA buffer.

 For all other ESP32 variants (like the most popular ‘original’ ESP32), [only *internal* SRAM can be used](https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-I2S-DMA/issues/55), so you will be limited to the ~200KB or so of 'free' SRAM (because of the memory used for your sketch amongst other things) regardless of how many megabytes of SPIRAM/PSRAM you may have connected.
