 ## Easily compile and flash binaries for the ESP32 and ESP31b
 You might also be interested in the branch for the ESP8266 and ESP8266EX: https://github.com/T-vK/docker-esp-sdk/
 
-## !!! This branch is completely untested for now!
-
 ## How to install
 
 If you don't have docker, install docker first: https://docs.docker.com/engine/installation/linux/
 
 ``` bash
 git clone -b esp32 https://github.com/T-vK/docker-esp-sdk.git
 cd docker-esp-sdk
-sudo docker build -t tavk/esp-sdk:0.1 .
+sudo docker build -t tavk/esp32-sdk:0.1 .
 ```
 
-## How to use
+## How to use examples
 
 ### Compiling binaries
 
 ``` bash
 sudo docker run -t -i -u esp \
--v /home/ubuntu/esp8266/esp-open-sdk/examples/blinky:/home/esp/shared_project \
-tavk/esp-sdk:0.1 \
-make
+-v /home/debian/esp-idf/examples/01_hello_world:/home/esp/shared_project \
+tavk/esp32-sdk:0.1 \
+make all
 ```
 
- - Replace `/home/ubuntu/esp8266/esp-open-sdk/examples/blinky` with the absolute path to the directory of the project oyu want to compile.
- - Replace `make` with whatever command is necessary to compile your binary/binaries.
+ - Replace `/home/debian/esp-idf/examples/01_hello_world` with the absolute path to the directory of the project oyu want to compile.
+ - Replace `make all` with whatever command is necessary to compile your binary/binaries.

 -v /home/ubuntu/esp8266/esp-open-sdk/examples/blinky:/home/esp/shared_project \
-tavk/esp-sdk:0.1 \
-esptool.py --port /dev/ttyUSB0 write_flash 0x00000 blinky-0x00000.bin 0x40000 blinky-0x40000.bin
+tavk/esp32-sdk:0.1 \
+make flash
 ```
 
- - Replace `/home/ubuntu/esp8266/esp-open-sdk/examples/blinky` with the absolute path to the directory that contains the files you want to flash.
+ - Replace `/home/debian/esp-idf/examples/01_hello_world` with the absolute path to the directory that contains the files you want to flash.
  - Replace `/dev/ttyUSB0` with the COM port that your ESP is connected to.
- - Replace `esptool.py --port /dev/ttyUSB0 write_flash 0x00000 blinky-0x00000.bin 0x40000 blinky-0x40000.bin` with whatever command is necessary to flash your binaries.

-### Flashing bootloaders
+ - Replace `make flash` with whatever command is necessary to flash your binaries.
 
-``` bash
-sudo docker run -t -i -u esp \
---device=/dev/ttyUSB0 \
--v /home/ubuntu/projects/esp-bootloader:/home/esp/shared_project \
-tavk/esp-sdk:0.1 \
-esptool.py --port /dev/ttyUSB0 write_flash --flash_mode dio --flash_size 32m 0x0 bootloader.bin
-```
+### Please refer to https://github.com/espressif/esp-idf for more indepth information on how to compile/flash for your ESP32
 
- - Replace `/home/ubuntu/projects/esp-bootloader` with the absolute path to the directory that contains the files you want to flash.
- - Replace `/dev/ttyUSB0` with the COM port that your ESP is connected to.
- -Replace `esptool.py --port /dev/ttyUSB0 write_flash --flash_mode dio --flash_size 32m 0x0 bootloader.bin` with whatever command is necessary to flash your binaries.
-
-### If the make file takes care of compiling AND flashing
-
-``` bash
-sudo docker run -t -i -u esp \
---device=/dev/ttyUSB0 \
--v /home/debian/espusb:/home/esp/shared_project \
-tavk/esp-sdk:0.1 \
-make ESP_ROOT=/home/esp/esp-open-sdk burn
-```
+## Testing
+I have compiled one example project successfully.  
+Since I don't have my ESP32 yet, I can't test if the flashing actually works.  
+But I'm sure you will tell me in the issues if something doesn't work. :)
 
- - Replace `/dev/ttyUSB0` with the COM port your esp is connected to.
- - Replace `/home/debian/espusb` with the absolute path to directory of the project you want to compile/flash.
- - Replace `make ESP_ROOT=/home/esp/esp-open-sdk burn` with the command necessary to compile and flash your project.
+I don't really know how to change the config wihtout going through menuconfig manually,  
+so that might be a problem.. I haven't really looked into it too much though.
