 # NerdSoloMiner
-The NerdSoloMiner v2
+**The NerdSoloMiner v2**
+
+This is a **free and open source project** that let you try to reach a bitcoin block with a small piece of hardware. 
+
+The main aim of this project is to let you **learn more about minery** and to have a beautiful piece of hardware in your desktop.
+
 
 Original project https://github.com/valerio-vaccaro/HAN

 ## Requirements
 - TTGO T-Display S3
 - 3D BOX [here](3d_files/)
 
-## Description
+### Project description
-ESP32 implementing Stratum protocol to mine on solo pool. Pool can be changed but originally works with ckpool.
+**ESP32 implementing Stratum protocol** to mine on solo pool. Pool can be changed but originally works with ckpool.
 
 This project is using ESP32-S3, uses WifiManager to modify miner settings and save them to SPIFF. 
 
 This miner is multicore and multithreads, each thread mine a different block template. After 1,000,000 trials the block in refreshed in order to avoid mining on old template.
 
-## TUTORIAL
+***Current project is still in developement and more features will be added***
-Create your own miner using the online tool ESPtool and the binary files that you will find in the bin folder.
+
+## Build Tutorial
+### Hardware requirements
+- TTGO T-Display S3 > Buy it on aliexpress or amazon
+- 3D BOX
+
+### Flash firmware
+Create your own miner using the online tool **ESPtool** and the **binary files** that you will find in the src/bin folder.
 If you want you can compile the entire project using Arduino, PlatformIO or Expressif IDF.
 
 1. Get a TTGO T-display S3
 1. Download this repository
 1. Go to ESPtool online: https://espressif.github.io/esptool-js/
-1. Load the firmware with the binaries from the bin folder.
+1. Load the firmware with the binaries from the src/bin folder.
+1. Plug your board and select each file from src/bin with its address 
 
-Complete tutorial on YouTube:
+#### Build troubleshooting
+1. Online ESPtool works with chrome, chromium, brave
+1. ESPtool recommendations: use 115200bps
+1. Build errors > If during firmware download upload stops, it's recommended to enter the board in boot mode. Unplug cable, hold right bottom button and then plug cable. Try programming
 
+### NerdMiner configuration
+After programming, you will only need to setup your Wifi and BTC address.
+
+1. Connect to NerdMinerAP
+1. Setup your Wifi Network
+1. Add your BTCaddress
+
+Optional you can select other pool:
+
+| Pool URL                 | Port | URL |
+|---                       |---   |---  | 
+| solo.ckpool.org          | 3333 | https://solo.ckpool.org/ |
+| btc.zsolo.bid            | 6057 | https://zsolo.bid/en/btc-solo-mining-pool |
+| eu.stratum.slushpool.com | 3333 | https://braiins.com/pool |
+
+**If you need to reboot your currentConfig**, hold right top button during 5 seconds and config will be deleted.
+
+#### Build video

-## DEVELOPMENT
+## Developers
-You can use platformio pltaform to develop this project.
+### Project guidelines
+- Current project was addapted to work with PlatformIO
+- Current project works with ESP32-S3 but any ESP32 can be used.
+- Partition squeme should be build as huge app
+- All libraries needed shown on platform.ini
+
+### On process
+- [x]  Move project to platformIO
+- [x]  Bug rectangle on screen when 1milion shares
+- [x]  Bug memory leaks
+- [x]  Bug Reboots when received JSON contains some null values
+- [ ]  Improve hashrate using Blockstream Jade miner code
+- [ ]  Add blockHeight to screen
+- [ ]  Add new screen with global mining stats
+- [ ]  Add support to control BM1397
+
+Enjoy

+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the usual convention is to give header files names that end with `.h'.
+It is most portable to use only letters, digits, dashes, and underscores in
+header file names, and at most one dot.
+
+Read more about using header files in official GCC documentation:
+
+* Include Syntax
+* Include Operation
+* Once-Only Headers
+* Computed Includes
+
