+===== New Project =====
+  * Create a new Arduino Project
+  * rename your .ino file into .cpp

+Now you are ready to go! \\
+If you want to open this project in Arduino IDE, rename the .cpp file back to .ino

 This should be great, since it has the sublime autocompletion, which is really missing in the original Arduiono IDE.

 **Important:** Don't forget to define the arduino-dist for both, the build and the upload command. Otherwise the upload command doesn't find the correct build-path, which as a suffix which is generated from the arduino-dist-dir.
+==== Error when moving host platform ====
+Today I moved my ino-project to a new computer, and forgot to erase the .build directory.
+I got nothing-saying error messages like this:

 ==== Compile existing project ====
 If we have an existing folder, with it's source files, we have to do a little adoption, so we can compile it with **ino**:\\
