+## OTA Updating
+There is OTA Web based updater built in, see settings.h
+```c++
+  #define HOST "esp8266-MeteoStation"
+  #define UPDATE_PATH "/update"
+  #define UPDATE_USERNAME "admin"
+  #define UPDATE_PASSWORD "admin"
+```
+
+open browser and head to esp8266-MeteoStation/update or IP/update after entering correct username/password combination you will be able to load new firmware and update it remotely.
+Keep in mind that overall sketch should be less than 50% of device memory.
+
+## Handling multi language texts
+There are language files containing strings which are used in UI.
+There are still some strings hardcoded to the weather station library.
+For now there is original English and Slovak file.
+Just include the correct file at the top of code.
+```c++
+  #include <language_EN.h>
+```
+
+As I am not able to reproduce steps for converting custom font files for extended language sets as Latin or Cyrillic, I used function to transliterate these characters which font cannot show to show basic version of there characters.
+
+You can adjust your characters by editing array in function
+```c++
+String Translit(String str) {
+    String special[] = {"Ľ" , "Š" , "Č" , "Ť" , "Ž" , "Ý" , "Á" , "Í" , "É" , "Ô" ,

+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.
