-S2FFT: JAX accelerated spin-spherical harmonic transforms
+Differentiable and accelerated spherical transforms with JAX
 =================================================================================================================
 
-Add some basic discussion about ``S2FFT`` here.
+`S2FFT` is a JAX package for computing Fourier transforms on the sphere
+and rotation group. It leverages autodiff to provide differentiable
+transforms, which are also deployable on hardware accelerators
+(e.g. GPUs and TPUs).
 
-Installation
-============
+More specifically, `S2FFT` provides support for spin spherical harmonic
+and Wigner transforms (for both real and complex signals), with support
+for adjoint transformations where needed, and comes with different
+optimisations (precompute or not) that one may select depending on
+available resources and desired angular resolution $L$.
 
-Add some basic installation instructions here.

+With this recursion to hand, the spherical harmonic coefficients of an 
+isolatitudinally sampled map may be computed as a two step process. First, 
+a 1D Fourier transform over longitude, for each latitudinal ring. Second, 
+a projection onto the real polar-d functions. One may precompute and store 
+all real polar-d functions for extreme acceleration, however this comes 
+with an equally extreme memory overhead, which is infeasible at L ~ 1024. 
+Alternatively, the real polar-d functions may calculated recursively, 
+computing only a portion of the projection at a time, hence incurring 
+negligible memory overhead at the cost of slightly slower execution. The
