High harmonic generation (HHG) in atomic and molecular gases builds the foundation of attosecond science. In recent experiments HHG has been demonstrated in solids for the first time. A theoretical analysis has revealed that one of the mechanisms driving HHG in semiconductors is similar to the one in atomic and molecular gases. As a result, many of the processes developed for attosecond science in gases can be adapted and applied to the condensed matter phase. In this tutorial, the connection between atomic and solid HHG is summarized with covering both theoretical and experimental work, and some implications for attosecond science in solids are presented.
