-=============
-
-Library for high-accuracy 4pi convolution on the sphere, which generates a
-total convolution data cube from a set of sky and beam `a_lm` and computes
-interpolated values for a given list of detector pointings.
-
-Algorithmic details:
-- the code uses `libsharp` SHTs to compute the data cube
-- shared-memory parallelization is provided via standard C++ threads.
-- for interpolation, the algorithm and kernel described in
-  https://arxiv.org/abs/1808.06736 are used. This allows very efficient
-  interpolation with user-adjustable accuracy.
-
-Installation and prerequisites:
-- execute `python3 setup.py install --user`. This requires the `g++` compiler.
-  If you want to compile with `clang`, use
-  `CC="clang -fsized-deallocation" python3 setup.py install --user`
-- `numpy` and `pybind11` are required for the Python interface.
-- For tests and demos, the package `pysharp` (also available in this repository)
-  is required.
-- For the unit tests, `pytest` is required.
