-# Caveats
+## Caveats
 While this may very well solve all possible Sudoku puzzles (including the one [designed against brute force algorithms](https://en.wikipedia.org/wiki/Sudoku_solving_algorithms)), the blanks in the puzzle, the harder it is, the more possible solutions there are, the more solutions it needs to parse, the longer it takes. As this is a computational heavy program, the more CPU you throw against it the faster it will solve issues.
+
+## Generating your own blocks
+To generate your own blocks, you could use the following code:
+```go
+func (solver *Solver) generate_blocks() []int {
+
+	var blocks []int
+	decvals := [9]int{49, 50, 51, 52, 53, 54, 55, 56, 57}
+
+	for counter := 123456789; counter <= 987654321; counter++ {
+
+		// Convert number to string ([]byte)
+		digits := strconv.Itoa(counter)
+
+		// Check if every number is only represented only once
+		var valid bool
+		valid = true
+		for decval := range decvals {
+			var count int
+			for digit := range digits {
+				if digits[digit] == byte(decvals[decval]) {
+					count = count + 1
+				}
+			}
+
+			if count != 1 {
+				valid = false
+			}
+		}
+
+		if valid {
+			blocks = append(blocks, counter)
+		}
+	}
+
+	return blocks
+
+}
+```
