Pranav Cherukupalli e6ba0f6281 DOCUMENTATION: Moved installation instructions to separate page (#561)
* DOCUMENTATION: Moved installation instructions to separate page

* Added Fedora to contents table
* Added Issue/Bug Report section to README
* Some minor improvements

* DOCUMENTATION: Rename directory doc to docs

* Also move ISSUE_TEMPLATE.md to docs directory

* DOCUMENTATION: Use current repo's files

* This makes it consistent instead  of having few local and few pointing to
  espressif/arduino-esp32 by all linking to local files

* DOCUMENTATION: Fix hyperlink to issue/bug template in contents

* DOCUMENTATION: contents: supress platform specific installation instruction

To use as a component of ESP-IDF
=================================================
- Download and install [esp-idf](https://github.com/espressif/esp-idf)
- Create blank idf project (from one of the examples)
- in the project folder, create a folder called components and clone this repository inside
```bash
mkdir -p components && \
cd components && \
git clone https://github.com/espressif/arduino-esp32.git arduino && \
cd .. && \
make menuconfig
```
- ```make menuconfig``` has some Arduino options
- "Autostart Arduino setup and loop on boot"
- If you enable this options, your main.cpp should be formated like any other sketch
```arduino
//file: main.cpp
#include "Arduino.h"
void setup(){
Serial.begin(115200);
}
void loop(){
Serial.println("loop");
delay(1000);
}
```
- Else you need to implement ```app_main()``` and call ```initArduino();``` in it.
Keep in mind that setup() and loop() will not be called in this case.
If you plan to base your code on examples provided in [esp-idf](https://github.com/espressif/esp-idf/tree/master/examples), please make sure move the app_main() function in main.cpp from the files in the example.
```arduino
//file: main.cpp
#include "Arduino.h"
extern "C" void app_main()
{
initArduino();
pinMode(4, OUTPUT);
digitalWrite(4, HIGH);
//do your own thing
}
```
- "Disable mutex locks for HAL"
- If enabled, there will be no protection on the drivers from concurently accessing them from another thread/interrupt/core
- "Autoconnect WiFi on boot"
- If enabled, WiFi will start with the last known configuration
- Else it will wait for WiFi.begin
- ```make flash monitor``` will build, upload and open serial monitor to your board
