 This command goes through positions in the input files and replaces the scores with new ones - generated from static eval - but slightly adjusted based on the scores in the original input file.
 
@@ -19,3 +19,18 @@ Currently the following options are available:
 `relative` - states that the adjustment should be bounded by a value relative in magnitude to the static eval value. After this token follows the maximum relative change - a floating point value greater than 0. For example a value of 0.1 only allows changing the static eval by at most 10% towards the score from the input file.
 
 `interpolate` states that the output score should be a value interpolated between static eval and the score from the input file. After this token follows the interpolation constant `t`. `t` of 0 means that only static eval is used. `t` of 1 means that only score from the input file is used. `t` of 0.5 means that the static eval and input score are averaged. It accepts values outside of range `<0, 1>`, but the usefulness is questionable.

+
+`transform rescore_fen` takes named parameters in the form of `transform rescore_fen param_1_name param_1_value param_2_name param_2_value ...` and flag parameters which don't require values.
+
+This command takes a path to the input file which contains one FEN per line and outputs a .bin or .binpack file with these positions rescored with specified depth search.
+
+Currently the following options are available:
+
+`input_file` - path to the input .epd file. Default: in.binpack.
+
+`output_file` - path to the output .bin or .binpack file. The file is opened in append mode. Default: out.binpack.
+
+`depth` - the search depth to use for rescoring. Default: 3.
