+
+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 organized `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.

+/*
+6.1.1b 20180715
+** Change default initial wifi config tool **
+Default initial wifi config tool has changed from WPS to Wifi Manager (local Access Point).
+Both WPS and Wifi Smartconfig are now optional and are disabled in user_config.h saving a massive 66k of code space.
+See _changelog.ino how to enable them again.
+Define WIFI_CONFIG_TOOL now contains the default behaviour once a SSID has been configured.
+If no SSID is configured making a wifi connection impossible the new define WIFI_CONFIG_NO_SSID will be used.
+While define WIFI_CONFIG_NO_SSID is set to WIFI_WPSCONFIG in user_config.h the compiler will check for define USE_WPS and if not enabled
+  WIFI_CONFIG_NO_SSID will default to WIFI_MANAGER using the webserver. If define USE_WEBSERVER is also not enabled
+  WIFI_CONFIG_NO_SSID will default to WIFI_SMARTCONFIG. If define USE_SMARTCONFIG is also not enabled
+  WIFI_CONFIG_NO_SSID will default to a new option WIFI_SERIAL allowing to enter wifi parameters to serial which is always possible.
+
+** Introduction _changelog.ino **
+Finally the changes can be found in a changelog where they belong. Release info will now be in _releasenotes.ino
