-CUDA_Compression
-================
+CUDA_Compression_tool
+=====================
+
+ To compile, simply 
+ $ make
+ Usage for compression: ./main -i {inputfile} -o {outputfile}
+
+ Usage for decompression: ./main -d 1 -i {inputfile} -o {outputfile}
+
+ ---
+ Default buffer size for the GPU pipeline is set to at the top of the main.c file. 
+ 	  Change BUFSIZE macro to change that variable.
+ MINSIZE defines the minimum size required to make use of the GPU processing. Setting this
+ 	  variable to a lower value can lead program to indefinite behaviour.
