You should choose file -> open… and choose the B16_32_8mm-LCD-112515.ino file.
That should open a bunch of files. Don’t open any more (do not open u8glib.h, arduino should find it for you).
Click Verify, and make sure there are no errors (you can ignore warnings, but errors mean it didn’t finish compiling). It should say “Done Compiling.” in the blue bar above the console output and below the text editor.
Then you can click upload, and at the end it should say “Done Uploading”.
