 ## Installation
 
 Install with
-```r
+
+``` r
 # install.packages("pak")
 pak::pak("SystemsBioinformatics/dataSheetParcr")
 ```
 
 ## Usage
+
 The package exports only one function: `parse_sheet()`, which parses one sheet and returns a list of named tables. The structure of a data sheet should be as follows
 
-```
-# Comment rows start with a hash in the left most cell
-# Blank lines are ignored, also if they contain tabs
-# The name of a table is printed above a table behind the > symbol
-# A table starts with a column header row in the left-most cell of a line
-
-> name_of_table
-# more optional comments or blank lines
-var1  var2  var3
-1     2     3
-4     5     6
-
-# more comments if needed
-> other_table
-var5  var6  var7
-1     2     3
-4     5     6
-```

 This sheet will be parsed by `parse_sheet()` and returns a list object with two named `tibble` objects:
 
-```
+```         
 $name_of_table
 # A tibble: 2 × 3
   var1  var2  var3
