initial commit; toolchains got left out bc of size reasons

DevEnviromentSetup.txt

+1.  To be able to compile projects for the ESP8266 and ESP32 microcontrollers, one
+    first needs to prepare the system:
+
+    - sudo apt-get install make unrar-free autoconf automake libtool gcc g++ gperf \
+        flex bison texinfo gawk ncurses-dev libexpat-dev python-dev python python-serial \
+        sed git unzip bash help2man wget bzip2
+
+    Users of Ubuntu/Debian versions higher than 14.04 may additionally require to
+
+    - sudo apt-get install libtool-bin
+
+2.  The toolchain needed to compile projects is the
+    - xtensa-lx106 (ESP8266)
+    - xtensa-esp32 (ESP32)
+
+    Those can be installed either through
+
+    - https://github.com/esp8266/esp8266-wiki/wiki/Toolchain for the ESP8266
+
+    or through
+
+    - esp-idf.readthedocs.io/en/latest/linux-setup.html (step 1) for the ESP32.
+
+3.  To flash the microcontrollers, a tool called "esptool" from Espressif itself
+    is needed. It (as well as the documentation) can be found at
+
+    - https://github.com/espressif/esptool
+
+4.  The last thing needed to develop your own programs for the ESP8266 or the
+    is the SDK you want to use. All official SDKs can be found at:
+
+    - espressif.com
+
+Alternative 1: For the ESP32, it is possible to combine to use
+
+- https://github.com/espressif/esp-idf
+
+which is the official development framework for the ESP32, instead of step 3 and
+which allready implements "esptool".
+
+Alternative 2: For the ESP8266 exists a community-project (which is officially
+recognized and linked to by Espressif itself) named "ESP-Open-SDK", which does
+steps 2 and 3 for you. It can be found at
+
+- https://github.com/pfalcon/esp-open-sdk
+
+Building your own projects: A great makefile that can easily be adjusted to your
+own projects settings can be found at
+
+- https://github.com/esp8266/source-code-examples
+
+=> Users of SDK-version 2.0.0 or higher have to add "crypto" to LIBS!
+   Furthermore, FW_FILE_2_ADDR has to be changed to 0x10000!
+
+Notes:  - If not configured otherwise in your program, the ESP8266 uses a
+          baudrate of 74880 baud to communicate via serial by default!
