+## Initial code
+
+We start with this procedural code that is mainly using if-else to handle errors.
+
+[Step 0: Procedural Code](src/main/kotlin/com/ropsample/arrow)
+
+## Refactoring steps
+
+### Solving the problem with Kotlin
+
+[Step 1: Method Extraction](src/main/kotlin/com/ropsample/methodExtraction)
+
+[Step 2: Lining up the functions](src/main/kotlin/com/ropsample/liningupthefunctions)
+
+[Step 3: Railway Oriented Programming](src/main/kotlin/com/ropsample/railwayorientedprogramming)
+
+### Using Arrow
+
+[Step 4: Using Either And FlatMap](src/main/kotlin/com/ropsample/arrow)
+
+[Step 5: Extracting error handling](src/main/kotlin/com/ropsample/arrowandinfix)
