+## Palindrome
+
+### Instructions
+
+In a file named `AlmostPalindrome.java` write a function `isAlmostPalindrome` that returns true if the String in parameter is almost palindrome.
+A word is considered "almost a palindrome" if removing one letter from the word makes it a palindrome.
+
+### Expected Functions
+
+```java
+public class AlmostPalindrome {
+    public static boolean isAlmostPalindrome(String s) {
+        // your code here
+    }
+}
+```
+
+### Usage
+
+Here is a possible `ExerciseRunner.java` to test your function :
+
+```java
+public class ExerciseRunner {
+    public static void main(String[] args) {
+        System.out.println(AlmostPalindrome.isAlmostPalindrome("reviver"));
+        System.out.println(AlmostPalindrome.isAlmostPalindrome("level"));
+    }
+}
+```
+
+and its output :
+
+```shell
+$ javac *.java -d build
+$ java -cp build ExerciseRunner
+true
+false
+$
+```
