-=========
+Rational Homotopy Theory
+========================
 
-At the time of writing this repo consists of some notes only.
-Will be about rational homotopy theory or something.
+Master thesis on Rational Homotopy Theory, the study of homotopy without
+torsion. The thesis mainly focuses on the Sullivan equivalence, which models
+rational spaces by commutative differential graded algebras (contrary to
+Quillen's dual approach which considers coalgebras). These objects are nice
+since they are very similar to polynomial rings and hence allow for easy
+calculations. The construction which allows us to go back and forth between
+spaces and algebras resembles ideas from differential geometry (namely De Rham's
+cochain complex), but can be applied to any topological space. Applications
+include the calculation of all rational homotopy groups of all spheres (in
+contrast to the integral case where many groups remain unknown as of today) and
+a result towards Adams' theorem (stating that only the spheres S0, S1, S3 and S7
+are H-spaces).
