-command.
+Project as a library
+~~~~~~~~~~~~~~~~~~~~
+
+When project is written as a library (where own examples or testing code use
+it), please use ``--lib="."`` option for :ref:`cmd_ci` command
+
+.. code-block:: yaml
+
+    script:
+        - platformio ci --lib="." --board=TYPE_1 --board=TYPE_2 --board=TYPE_N
+
+Library dependecies
+~~~~~~~~~~~~~~~~~~~
+
+There 2 options to test source code with dependent libraries:
+
+Install dependent library using :ref:`librarymanager`
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: yaml
+
+    install:
+        - pip install -U platformio
+
+        #
+        # Libraries from PlatformIO Library Registry:
+        #
+        # http://platformio.org/#!/lib/show/1/OneWire
+        platformio lib install 1
+
+Manually download dependent library and include in build process via ``--lib`` option
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: yaml
+
+    install:
+        - pip install -U platformio
+
+        # download library to the temporary directory
+        wget https://github.com/PaulStoffregen/OneWire/archive/master.zip -O /tmp/onewire_source.zip
+        unzip /tmp/onewire_source.zip -d /tmp/
+
+    script:
+        - platformio ci --lib="/tmp/OneWire-master" --board=TYPE_1 --board=TYPE_2 --board=TYPE_N
+
+Custom Build Flags
+~~~~~~~~~~~~~~~~~~
+
+PlatformIO allows to specify own build flags using :envvar:`PLATFORMIO_BUILD_FLAGS` environment
+
+.. code-block:: yaml
+
+    env:
+        - PLATFORMIO_CI_SRC=path/to/test/file.c PLATFORMIO_BUILD_FLAGS="-D SPECIFIC_MACROS_PER_TEST_ENV -I/extra/inc"
+        - PLATFORMIO_CI_SRC=examples/file.ino
+        - PLATFORMIO_CI_SRC=path/to/test/directory
+
+    install:
+        - pip install -U platformio
+
+        export PLATFORMIO_BUILD_FLAGS=-D GLOBAL_MACROS_FOR_ALL_TEST_ENV
+
+
+For the more details, please follow to
+:ref:`available build flags/options <projectconf_build_flags>`.
+
+
+Advanced configuration
+~~~~~~~~~~~~~~~~~~~~~~
+
+PlatformIO allows to configure multiple build environments for the single
+source code using :ref:`projectconf`.
+
+Instead of ``--board`` option, please use :option:`platformio ci --project-conf`
+
+.. code-block:: yaml
+
+    script:
+        - platformio ci --project-conf=/path/to/platoformio.ini
