 CombinePDF is a nifty model, written in pure Ruby, to parse PDF files and combine (merge) them with other PDF files, watermark them or stamp them (all using the PDF file format and pure Ruby code).
 
 # Install
 
 Install with ruby gems:
-```
+
+```ruby
 gem install combine_pdf
 ```
 
 ## Combine/Merge PDF files or Pages
+
 To combine PDF files (or data):
+
 ```ruby
 pdf = CombinePDF.new
 pdf << CombinePDF.new("file1.pdf") # one way to combine, very fast.
 pdf << CombinePDF.new("file2.pdf")
 pdf.save "combined.pdf"
 ```
+
 Or even a one liner:
+
 ```ruby
 (CombinePDF.new("file1.pdf") << CombinePDF.new("file2.pdf") << CombinePDF.new("file3.pdf")).save("combined.pdf")
 ```
+
 you can also add just odd or even pages:
+
 ```ruby
 pdf = CombinePDF.new
 i = 0
 CombinePDF.new("file.pdf").pages.each do |page|
   i += 1

 ## Add content to existing pages (Stamp / Watermark)
 
 To add content to existing PDF pages, first import the new content from an existing PDF file. After that, add the content to each of the pages in your existing PDF.
 
 In this example, we will add a company logo to each page:
+
 ```ruby
 company_logo = CombinePDF.new("company_logo.pdf").pages[0]
 pdf = CombinePDF.new "content_file.pdf"
 pdf.pages.each {|page| page << company_logo} # notice the << operator is on a page and not a PDF object.
 pdf.save "content_with_logo.pdf"
 ```
+
 Notice the << operator is on a page and not a PDF object. The << operator acts differently on PDF objects and on Pages.
 
 The << operator defaults to secure injection by renaming references to avoid conflics. For overlaying pages using compressed data that might not be editable (due to limited filter support), you can use:
+
 ```ruby
 pdf.pages(nil, false).each {|page| page << stamp_page}
 ```
+
 ## Page Numbering
+
 adding page numbers to a PDF object or file is as simple as can be:
+
 ```ruby
 pdf = CombinePDF.new "file_to_number.pdf"
 pdf.number_pages
 pdf.save "file_with_numbering.pdf"
 ```
+
 Numbering can be done with many different options, with different formating, with or without a box object, and even with opacity values - see documentation.
 
 ## Loading PDF data
+
 Loading PDF data can be done from file system or directly from the memory.
 
 Loading data from a file is easy:
+
 ```ruby
 pdf = CombinePDF.new("file.pdf")
 ```
+
 you can also parse PDF files from memory:
+
 ```ruby
 pdf_data = IO.read 'file.pdf' # for this demo, load a file to memory
 pdf = CombinePDF.parse(pdf_data)
 ```
+
 Loading from the memory is especially effective for importing PDF data recieved through the internet or from a different authoring library such as Prawn.
