  SI Toolbox is a package for estimating the isotropy violation in the CMB sky.
It can be used for estimating the BipoSH coefficients, Dipole modulation, and
Doppler boost parameters etc. Different Fortran subroutines, provided with this
package, can help the users to develop their independent Fortran codes. This
document is an overview of the SI Toolbox installation guide, standalone
facilities, and Fortran subroutines. The SI Toolbox package can be downloaded
from https://github.com/SIToolBox/SIToolBox.
