-        Move the mouse pointer to the data plot to highlight (yellow).  When right clicking and holding, a pop-up (context) menu will appear. 
-        Select from the context menu <b>Select Data for fitting</b>.
-        A new tab with the name of the data selected will appears. Select a model used for the fit
-        from the combo box. Model's parameters will be display.Set initial parameters if need.
-        Check at least one parameter to fit.Click on <b> Fit</b> button.
-        New parameters values will be displayed as well as error and new chi square associated
-        with the fit operation.
-        The model will be replotted with its new values.
-        Errors will be display on the statusbar.
-        Single fit can also be perform on the "<b>simultaneous fit </b>" tab is parameters are previously 
-        selected on the page corresponding to a model name check. if one model is check, click 
-        on <b> constraint fit </b> button to perform a single fit. results will be displayed on 
-        the appropriate tab.
+        One of two fit-engines can be chosen from the Fitting menu bar. The Simple Fit-engine uses Scipy's leasqr 
+        and the Complex Fit-Engine is a custom optimizer that provides a better chance 
+        to find the global minimum of the chi2 but that requires longer computation time.
+        In order to set a data to a control panel (FitPage), see the "DataLoader Help".
+        Once a data set to the FiPage, select a model from the combo box. 
+        The default parameters of the model will be display. Set initial parameters if need.
+        Check and uncheck parameters to fit/fix. Click the <b> 'Fit'</b> button.
+        When the fitting is finished, the resultant parameter values will be displayed with the errors. If a error is missing, it generally means 
+        that the corresponding parameter is not very depending on the model. The chisq/Npt_fit and the plot associated
+        with the fit operation will be also updated.
