**Abstract:** These notes are written for the ‘‘RKHS Learning Seminars’’ at the Institute of Applied Mathematics, METU. It aims to introduce the audience to the fundamental ideas of elementary Hilbert space theory. We assume the participants have good knowledge of linear algebra and advanced calculus. The material covered is relatively standard and contains no new mathematics. The book “A Primer on Reproducing Kernel Hilbert Spaces” by J. H. Manton and P. Amblard (Manton & Amblard, 2015) was chosen as the principal reference for this seminar series. Hence, it shaped the structure of these notes. Additional references used in these notes, plus references that can be used for further studies, are listed below.
