+
+all '\newcommand' are applied to the cell of the tabular and the tabular is parsed to extract data
+
+## General rules
+
+The general rules to extract data correctly are:
+
+- A `$` must not follow another `$` put space between them.
+
+- The column number must be the same on each line in `tabular`
+
+- Please respect the format of each tabular
+
+- Use standard $\LaTeX$ for the  `multicolumn ` command and not a wrapper
+
+- In general use standard $\LaTeX$ instead of dirty form for example
+
+  ```latex
+  $A''$ % Bad
+  $A^"$ % Bad
+  $A^{\prime\prime}$ %Good
+  ```
+
+- D'ont put comment at the end of  `tabular `  row (this cause a TexSoup bug)
+- Only  `tabular ` environment is supported please convert `longtable ` and  other table format to  `tabular 
+- Only  `\newcommand ` are supported please  convert  `\def ` and  `\NewDocumentCommand `
+- After executing all commands the basis and methods name must be $\LaTeX$ free (only plan text)
+
+### Unsafe values
+
+Unsafe value (value that must not included in the statistics table and graph) must be in emphasis like
+
+$\emph{6.2}$
+
+```latex
+\emph{6.2}
+```
+
