 ### Description:
 
-The program will open two matplotlib windows, one with a corner plot and another one with a list of CheckButtons and TextBoxes to interactively select the parameters to be plotted in the corner plot, and edit the individual titles/labels shown in the plot.
+The program will open two `matplotlib` windows, one with a corner plot and another one with a list of `CheckButtons` and `TextBoxes` to interactively select the parameters to be plotted in the corner plot, and edit the individual titles/labels shown.
 
-The three last CheckButtons in the list allows to turn on and off the smoothed 2D `contours` in the [Corner Plot](https://corner.readthedocs.io/), and to play with `Titles` and `XYlabels` in the plot.

 The program also displays a summary with the main statistics of the available parameters in the chain file using the samples selected by the user.
 
+In the `tkinter` version, a `tk` window is opened with `buttons` and `textboxes` for every parameter, a `matplotlib` plot embedded, and a button to Update the plot when needed.

 ### Usage:
 
 **Basic:** The user must provide the `path/name` to the MCMC XSPEC chain FITS file.
