 This project aims to be a wireless terminal emulator that'll work with the likes of 
 Arduino, AVR, PIC, STM8, STM32, mbed etc, anything with UART, even your USB-serial dongle will work.

+Connect it to the master device via UART and use the terminal on the built-in web page for debug logging, 
 remote control etc. It works like a simple LCD screen, in a way.
 
 It lets you make simple UI (manipulating the screen with ANSI sequences) and receive input from buttons on
-the webpage (and keyboard on PC). Touch input is a possibility but not currently implemented.

 ## Project status
 
-*Still far from finished and also there's like zero documentation, but you can give it a spin if you wish.*
+*Almost finished, still possibly buggy, but it looks promising. Most of the features are there now.*
 
 - We have a working **2-way terminal** (UART->ESP->Browser and vice versa) with real-time update via websocket.
   
   This means that what you type in the browser is sent to UART0 and what's received on UART0 is processed by the 
-  ANSI parser and applied to the internal screen buffer. You'll also immediately see the changes in your browser.

+  There's a filter in the way that discards garbage characters (like unicode and most ASCII outside 32-126).
   
-  For a quick test, try connecting the UART0 Rx and Tx to make a loopback interface.

-  You should then see what you type & can even try out the ANSI sequences.
+  *NOTE: Use the bare module, not something like LoLin or NodeMCU with a FTDI, it'll interfere*. 
-  
+  You should then directly see what you type & can even try some ANSI sequences, right from the browser.
-  Arrow keys generate ANSI sequences, ESC sends literal ASCII code 27 - should be all you need to get started.
   
 - All ANSI sequences that make sense, as well as control codes like Backspace and CR / LF are implemented.
-  Set colors with your usual `\e[31;1m` etc (see Wikipedia). `\e` is the ASCII code 27 (ESC).

+- To resize the screen, send `\e]W<rows>;<cols>\a` (it's an OSC code, terminated by ST).
