+# Reproject
+
+Implementation in [Julia](https://julialang.org/) of the
+[`reproject`](https://github.com/astropy/reproject) package by Thomas
+Robitaille, part of the Astropy project.
+
+This package can be used to reproject Astronomical Images from one world coordinate to another. By reproject we mean re-gridding of images using interpolation (i.e changing the pixel resolution, orientation, coordinate system).
+
+Installation
+-------
+
+Reproject.jl is avilable for Julia 1.0 and later versions and can be installed with [Julia built-in package manager](https://docs.julialang.org/en/v1/stdlib/Pkg/).
+
+```julia-repl
+julia> import Pkg; Pkg.add("Reproject")
+```
+
+Usage
+-------
+
+After installing the package, you can start using it with
+
+```julia-repl
+julia> using Reproject
+
+julia> result = reproject(input_data, output_projection)
+```
+
+This returns a tuple of reprojected Image and footprint.
+
+
+Reprojecting Images
+-------
+
+To reproject Astronomical Images, primary requirements are Image data (2D Matrix), world cordinate frame of input Image and required output frame in which it needs to be reprojected.
+
+The Image data and input frame is given together as an [ImageHDU](http://juliaastro.github.io/FITSIO.jl/latest/index.html) or [FITS](https://github.com/JuliaAstro/FITSIO.jl) file or name of the FITS file in `input_data`. A keyword argument `hdu_in` can be given while using FITS or FITS file name to specify specific HDU in FITS file.
+
+The `output_projection` is the output world coordinate frame and needs to be a a [WCSTransform](https://github.com/JuliaAstro/WCS.jl) or an [ImageHDU](http://juliaastro.github.io/FITSIO.jl/latest/index.html) or [FITS](https://github.com/JuliaAstro/FITSIO.jl) file or name of the FITS file. A keyword argument `hdu_out` can be given while using FITS or FITS file name to specify specific HDU in FITS file.
+WCS information is extracted from header when ImageHDU or FITS file is given as `output_projection`.
+
+Order of Interpolation can be specified by keyword `order` (i.e 0, 1(default), 2).
+The dimensions of output Image can be given by keyword `shape_out`. This can be used to change resolution.
+
+
+Example
+-------
+```julia-repl
+julia> using Reproject, FITSIO
+
+julia> input_data = FITS("gc_msx_e.fits")
+
+julia> output_projection = FITS("gc_2mass_k.fits")
+
+julia> result = reproject(input_data, output_projection, shape_out = (1000,1000), order = 2, hdu_in = 1, hdu_out = 1)
+```
