+How to build PlatformIO based project
+=====================================
+
+1. `Install PlatformIO <http://docs.platformio.org/en/stable/installation.html>`_
+2. Download `development platform with examples <https://github.com/platformio/platform-espressif8266/archive/develop.zip>`_
+3. Extract ZIP archive
+4. Run these commands:
+
+.. code-block:: bash
+
+    # Change directory to example
+    > cd platform-espressif32/examples/espidf-ble-adv
+
+    # Build project
+    > platformio run
+
+    # Upload firmware
+    > platformio run --target upload
+
+    # Build specific environment
+    > platformio run -e esp32dev
+
+    # Upload firmware for the specific environment
+    > platformio run -e esp32dev --target upload
+
+    # Clean build files
+    > platformio run --target clean

+
+This directory is intended for the project specific (private) libraries.
+PlatformIO will compile them to static libraries and link to executable file.
+
+The source code of each library should be placed in separate directory, like
+"lib/private_lib/[here are source files]".
+
+For example, see how can be organised `Foo` and `Bar` libraries:
+
+|--lib
+|  |--Bar
+|  |  |--docs
+|  |  |--examples
+|  |  |--src
+|  |     |- Bar.c
+|  |     |- Bar.h
+|  |--Foo
+|  |  |- Foo.c
+|  |  |- Foo.h
+|  |- readme.txt --> THIS FILE
+|- platformio.ini
+|--src
+   |- main.c
+
+Then in `src/main.c` you should use:
+
+#include <Foo.h>
+#include <Bar.h>
+
+// rest H/C/CPP code
+
+PlatformIO will find your libraries automatically, configure preprocessor's
+include paths and build them.
+
+See additional options for PlatformIO Library Dependency Finder `lib_*`:
+
+http://docs.platformio.org/en/stable/projectconf.html#lib-install

+How to build PlatformIO based project
+=====================================
+
+1. `Install PlatformIO <http://docs.platformio.org/en/stable/installation.html>`_
+2. Download `development platform with examples <https://github.com/platformio/platform-espressif8266/archive/develop.zip>`_
+3. Extract ZIP archive
+4. Run these commands:
+
+.. code-block:: bash
+
+    # Change directory to example
+    > cd platform-espressif32/examples/espidf-coap-server
+
+    # Build project
+    > platformio run
+
+    # Upload firmware
+    > platformio run --target upload
+
+    # Build specific environment
+    > platformio run -e esp32dev
+
+    # Upload firmware for the specific environment
+    > platformio run -e esp32dev --target upload
+
+    # Clean build files
+    > platformio run --target clean

+
+This directory is intended for the project specific (private) libraries.
+PlatformIO will compile them to static libraries and link to executable file.
+
+The source code of each library should be placed in separate directory, like
+"lib/private_lib/[here are source files]".
+
+For example, see how can be organised `Foo` and `Bar` libraries:
+
+|--lib
+|  |--Bar
+|  |  |--docs
+|  |  |--examples
+|  |  |--src
+|  |     |- Bar.c
+|  |     |- Bar.h
+|  |--Foo
+|  |  |- Foo.c
+|  |  |- Foo.h
+|  |- readme.txt --> THIS FILE
+|- platformio.ini
+|--src
+   |- main.c
+
+Then in `src/main.c` you should use:
+
+#include <Foo.h>
+#include <Bar.h>
+
+// rest H/C/CPP code
+
+PlatformIO will find your libraries automatically, configure preprocessor's
+include paths and build them.
+
+See additional options for PlatformIO Library Dependency Finder `lib_*`:
+
+http://docs.platformio.org/en/stable/projectconf.html#lib-install

+How to build PlatformIO based project
+=====================================
+
+1. `Install PlatformIO <http://docs.platformio.org/en/stable/installation.html>`_
+2. Download `development platform with examples <https://github.com/platformio/platform-espressif8266/archive/develop.zip>`_
+3. Extract ZIP archive
+4. Run these commands:
+
+.. code-block:: bash
+
+    # Change directory to example
+    > cd platform-espressif32/examples/espidf-peripherals-uart
+
+    # Build project
+    > platformio run
+
+    # Upload firmware
+    > platformio run --target upload
+
+    # Build specific environment
+    > platformio run -e esp32dev
+
+    # Upload firmware for the specific environment
+    > platformio run -e esp32dev --target upload
+
+    # Clean build files
+    > platformio run --target clean

+
+This directory is intended for the project specific (private) libraries.
+PlatformIO will compile them to static libraries and link to executable file.
+
+The source code of each library should be placed in separate directory, like
+"lib/private_lib/[here are source files]".
+
+For example, see how can be organised `Foo` and `Bar` libraries:
+
+|--lib
+|  |--Bar
+|  |  |--docs
+|  |  |--examples
+|  |  |--src
+|  |     |- Bar.c
+|  |     |- Bar.h
+|  |--Foo
+|  |  |- Foo.c
+|  |  |- Foo.h
+|  |- readme.txt --> THIS FILE
+|- platformio.ini
+|--src
+   |- main.c
+
+Then in `src/main.c` you should use:
+
+#include <Foo.h>
+#include <Bar.h>
+
+// rest H/C/CPP code
+
+PlatformIO will find your libraries automatically, configure preprocessor's
+include paths and build them.
+
+See additional options for PlatformIO Library Dependency Finder `lib_*`:
+
+http://docs.platformio.org/en/stable/projectconf.html#lib-install

+How to build PlatformIO based project
+=====================================
+
+1. `Install PlatformIO <http://docs.platformio.org/en/stable/installation.html>`_
+2. Download `development platform with examples <https://github.com/platformio/platform-espressif8266/archive/develop.zip>`_
+3. Extract ZIP archive
+4. Run these commands:
+
+.. code-block:: bash
+
+    # Change directory to example
+    > cd platform-espressif32/examples/espidf-storage-sdcard
+
+    # Build project
+    > platformio run
+
+    # Upload firmware
+    > platformio run --target upload
+
+    # Build specific environment
+    > platformio run -e esp32dev
+
+    # Upload firmware for the specific environment
+    > platformio run -e esp32dev --target upload
+
+    # Clean build files
+    > platformio run --target clean

+This directory is intended for the project specific (private) libraries.
+PlatformIO will compile them to static libraries and link to executable file.
+
+The source code of each library should be placed in separate directory, like
+"lib/private_lib/[here are source files]".
+
+For example, see how can be organised `Foo` and `Bar` libraries:
+
+|--lib
+|  |--Bar
+|  |  |--docs
+|  |  |--examples
+|  |  |--src
+|  |     |- Bar.c
+|  |     |- Bar.h
+|  |--Foo
+|  |  |- Foo.c
+|  |  |- Foo.h
+|  |- readme.txt --> THIS FILE
+|- platformio.ini
+|--src
+   |- main.c
+
+Then in `src/main.c` you should use:
+
+#include <Foo.h>
+#include <Bar.h>
+
+// rest H/C/CPP code
+
+PlatformIO will find your libraries automatically, configure preprocessor's
+include paths and build them.
+
+See additional options for PlatformIO Library Dependency Finder `lib_*`:
+
+http://docs.platformio.org/en/stable/projectconf.html#lib-install
