 # PDF Scrub
 
-Scrubs encrypted compressed PDF files for text watermarks and metadata.
+_Scrubs encrypted compressed PDF files for text watermarks and metadata._
+
+1. Decrypts the PDF if it's encrypted
+2. Uncompresses the PDF
+3. Removes metadata (Xpacket)
+4. Tries to naively remove text based watermarks by matching objects which number of occurrences, is the same as the PDF page count. If multiple objects match, produce a pdf for each.
+5. Optionally compresses the PDF again if `--no-compress` is not given as a command line argument.
