+# LevenshteinSimilarity Class
+
+**Static class providing extension methods for calculating the Levenshtein similarity between two strings.**
+
+## Class Members
+
+```csharp
+CalculateLevenshteinSimilarity(
+    string source,
+    string target)
+```
+
+Calculates the Levenshtein similarity between two strings.
+
+### Parameters
+
+- `source` (Type: `string`): The source string for comparison.
+- `target` (Type: `string`): The target string for comparison.
+
+### Returns
+
+- Type: `int`
+- Description: An integer representing the Levenshtein similarity between the two strings.
+
+### Example
+
+```csharp
+using NetPlus.Algorithms.Comparison;
+
+// Example strings
+string source = "Hello World";
+string target = "Hello";
+
+// Calculating Levenshtein similarity
+int similarity = source.CalculateLevenshteinSimilarity(target);
+
+// Displaying similarity
+Console.WriteLine(similarity);
+```
+
+### Usage
+
+To use the `LevenshteinSimilarity` class, simply call the `CalculateLevenshteinSimilarity` method with the appropriate parameters.
+
+```csharp
+// Example usage
+int similarity = source.CalculateLevenshteinSimilarity(target);
+```
+
+### Remarks
+
+The `LevenshteinSimilarity` class uses the Levenshtein algorithm to calculate the similarity between two strings. It returns an integer value representing the similarity between the two strings.
