This chapter should give you a gentle introduction into data analysis with YODA. It's a sort of ''mini-tutorial'', not a reference. Its best usage is in front of a workstation running both YODA and PAW++. Things are kept very simple to convey the basics. After the principle operation is understood, the reader should then read the section on YODA's full command set and language, probably diving right into his or her ''real'' physical data. Users who are already familiar with YODA's basics should probably skip this section.
