 ## Features
 
 - AHP algorithm implementation
 - User-friendly interface
 - Three types of sensitivity analysis:
-  - Weighted criteria attribute chart
-  - Small changes simulation
-  - One way sensitivity analysis
+  - Weighted criteria attribute chart[^1]
+  - Small changes simulation[^2]
+  - One way sensitivity analysis[^3]
 - Project saving and loading
 - Exporting project to csv
 
+[^1]: Calculates the contribution of each criterion and subcriterion to the overall priority value of alternatives and visualizes the contributions in a bar chart.
+[^2]: Calculates the program results with random adjustments to comparisons, records the alternative with the highest priority for each adjustment set, and presents the frequency of each alternative's "wins" in a bar chart.
+[^3]: Allows users to select a comparison in the AHP model and visualize how changing its value affects alternative priorities in a graph.
