+Nanopb example "simple"
+=======================
+
+This example demonstrates the very basic use of nanopb. It encodes and
+decodes a simple message.
+
+The code uses four different API functions:
+
+  * pb_ostream_from_buffer() to declare the output buffer that is to be used
+  * pb_encode() to encode a message
+  * pb_istream_from_buffer() to declare the input buffer that is to be used
+  * pb_decode() to decode a message
+
+Example usage
+-------------
+
+On Linux, simply type "make" to build the example. After that, you can
+run it with the command: ./simple
+
+On other platforms, you first have to compile the protocol definition using
+the following two commands::
+
+  protoc -osimple.pb simple.proto
+  python nanopb_generator.py simple.pb
+
+After that, add the following four files to your project and compile:
+
+  simple.c  simple.pb.c  pb_encode.c  pb_decode.c
+
