The talk is intended as a gentle introduction to the subject of Higher Spin Gravity with emphasis on general ideas and methods.  I am going to discuss the following topics:

1. L-infinity algebras as a universal approach to classical field theory.
2. The origin of Higher Spin Algebras.
3. Interactions as deformations of L-infinity algebras.
4. Higher Spin Gravity in four dimensions and its integrability.
5. Chiral models of higher spin gravity. (If I have time.)
