 Automatically align polygons with gridded (raster) data such as images and surface models.
 
 ## Detail
-pixelshift is a CLI tool for automatic conflation of a polygon Shapefile with gridded data. The conflation aligns the geometry using Stochastic Gradient Descent (SGD) optimisaiton. 
+pixelshift is a command-line interface (CLI) tool for automatic conflation of a polygon Shapefile with grid data such as images and surface models. The conflation aligns a 2D geometry using Stochastic Gradient Descent (SGD) optimisation.
 
-    pixelshift inputGrid polygonsShapefile maxIterations
-    displacementMagnitude numCores
+    pixelshift inputGrid polygonsShapefile maxIterations displacementMagnitude numCores
 
 The parameters are (order matters):
 
     inputGrid = a geotiff.
     polygonsShapeFile = Shapefile of polygons in partial alignment with the inputGrid.  
     maxIterations = number of iterations for SGD.
     displacementMagnitude = bound for random distribution used in SGD.
-    numCores = number of cores used for the optimisation.
+    numCores = number of cores used for the parallelisation of the optimisation.
+	outputFilePath = path and name of output file (.shp) of adjusted features.
