+# Lab 11: Contact List
+
+
+Let's build a program to manage a list of contacts. To start, we'll build a CSV ('comma separated values') together, and go over how to load that file. Headers might consist of `name`, `favorite fruit`, `favorite color`. Open the CSV, convert the lines of text into a **list of dictionaries**, one dictionary for each user. The text in the header represents the **keys**, the text in the other lines represent the **values**.
+
+```python
+with open('contacts.csv', 'r') as file:
+    lines = file.read().split('\n')
+    print(lines)
+```
+
+Once you've processed the file, your list of contacts will look something like this...
+```python
+contacts = [
+    {'name':'matthew', 'favorite fruit':'blackberries', 'favorite color':'orange'},
+    {'name':'sam', 'favorite fruit':'pineapple' ...}
+]
+```
+
+*Note: There is a `csv` library in Python that will do much of this for you. It is what you would use normally in a project, but for this lab you need to write all the logic yourself.*
+
+## Version 2
+
+Implement a CRUD REPL
+
+- **C**reate a record: ask the user for each attribute, add a new contact to your contact list with the attributes that the user entered.
+- **R**etrieve a record: ask the user for the contact's name, find the user with the given name, and display their information
+- **U**pdate a record: ask the user for the contact's name, then for which attribute of the user they'd like to update and the value of the attribute they'd like to set.
+- **D**elete a record: ask the user for the contact's name, remove the contact with the given name from the contact list.
+
+## Version 3
+
+When REPL loop finishes, write the updated contact info to the CSV file to be saved. I highly recommend saving a backup `contacts.csv` because you likely won't write it correctly the first time.
