 ## Guide to basic functionality
+
 ### Opening the file
 
 You can open ODS file (OpenDocument Spreadsheet) like this
-````ruby
+
+```ruby
 workbook = Rspreadsheet.open('./test.ods')
 workbook = Rspreadsheet.open('./test.fods') # gem supports flast OpenDocument format
-````
+```
+
 and access its first sheet like this
-````ruby
+
+```ruby
 sheet = workbook.worksheet(1)
-````
+```
+
 ### Accessing cells
 
 you can get and set contents of cells using "verbatim" syntax like
-````ruby
+
+```ruby
 sheet.row(5).cell(4).value 
 sheet.row(5).cell(4).value = 10
-````
+```
+
 or using "brief" syntax like
-````ruby
+
+```ruby
 sheet[5,4]
 sheet[5,4] = 10
-````
+```
 
 You can mix these two at will, for example like this
-````ruby
+
+```ruby
 row = sheet.row(5)
 row[4] = 10
-````
+```
 
 ### Working with images
+
+```ruby
 sheet.insert_image_to('10.21mm','15mm','image.png')
 i = sheet.images.first
 i.move_to('100mm','99.98mm')
+```
+
+### Saving
+
+The file needs to be saved after doing changes.

-The file needs to be saved after doing changes. 
-````ruby
+```ruby
 workbook.save
 workbook.save('new_filename.ods')    # changes filename and saves
 workbook.save(any_io_object)         # file can be saved to any IO like object as well
 workbook.to_io                       # coverts it to IO object which can be used to 
 anotherIO.write(workbook.to_io.read) # send file over internet without saving it first
-````
+```
 
 ### Creating fresh new file
+
 You may name the spreadsheet on creation or at first save.
 
-````ruby
+```ruby
 workbook = Rspreadsheet.new
 workbook.save('./filename.ods')      # filename nust be provided at least on first save
 workbook2 = Rspreadsheet.new('./filename2.fods', format: :flat)
@@ -57,21 +72,23 @@ workbook2.save
 If you want to use the fods flat format, you must create it as such.
 
 ### Date and Time
+
 OpenDocument and ruby have different models of date, time and datetime. Ruby containg three different objects. Time and DateTime cover all cases, Date covers dates only. OpenDocument distinguishes two groups - time of a day (time) and everything else (date). To simplify things a little we return cell values containg time of day as Time object and cell values containg datetime of date as DateTime. I am aware that this is very arbitrary choice, but it is very practical. This way and to some extend the types of values from OpenDocument are preserved when read from files, beeing acted upon and written back to spreadshhet.
 
-### Merged cells 
-Even when a cell spans more rows and collumns, you must access by coordinates of its topleft corner. In fact, the "hidden" cells under are still there and their content is usually preserved.

 ## Conventions
-  * **all indexes are 1-based**. This applies to rows, cells cordinates, and all array like structures like list od  worksheets etc. Spreadsheet world is 1-based, ruby is 0-based so I had to make a decision. I intend to make an global option for this, but in early stage I need to keep things simple.
-  * with numeric coordinates row always comes before col as in  (row,col)
-  * with alphanumerical col always comes before row as in F12
-  * Shorter syntax worksheet[x,y] returns value, longer syntax worksheet.cell(x,y) return cell objects. This allows to work conviniently with values using short syntax and access the cell object if needed (to access formatting for example).
-  * Singular and plural like sheet/sheets, row/rows, cell/cells can be used intergangebly.
