-As you may recall from previous lessons, in Python, you declare a variable by writing the variable name on the left side of the assignment operator (`=`) and the value to assign on the right side:
+In this workshop, you will create a program called caesar cipher which is an encryption method that shifts letters in the alphabet to encode messages.
 
-```py
+Start by creating a variable called `shift` and assign the value `5` to your new variable.
-variable_name = value

-In previous lessons, you learned about different data types you can store in a variable. You just assigned an integer value. Now you need to assign a string, which is a sequence of characters enclosed by either single or double quotes:
-
-```py
-string_1 = 'I am a string'
-string_2 = "I am also a string"
-```
-
 Declare another variable called `alphabet` and assign the string `abcdefghijklmnopqrstuvwxyz` to this variable.

-As you can see from the output, the shifted alphabet starts at the letter `f` because `shift` has the value `5`. But now the first five letters of the alphabet – `a`, `b`, `c`, `d` and `e` – are missing from the shifted alphabet, so you'll need to add them at the end of the shifted alphabet.

But now the first five letters of the alphabet – `a`, `b`, `c`, `d` and `e` – are missing from the shifted alphabet, so you'll need to add them at the end of the shifted alphabet. You can use the `+` operator to concatenate the missing portion of the alphabet.

-The `+` operator is used to combine two or more strings together in a process called concatenation like this:
-
-```py
-greeting = 'Hello' + ' ' + 'World'
-print(greeting) # Hello World
-
-```
 
 Modify the existing assignment of the `shifted_alphabet` variable: use the slicing syntax to extract the missing first portion of `alphabet` and concatenate it to `alphabet[shift:]`.

-Now that you've implemented the basic functionalities of the cipher, it's time to add some validation. For that, you'll need an `if` statement. Here's a reminder of the syntax for an `if` statement:

 At the beginning of your function body, create an `if` statement. For now, use `True` as the condition, and within the `if` statement body return the string `Shift must be an integer value.`
