+    "You are tasked with writing budgetting software, but at this point, things are a mess. You have two files. `budget_prices.txt` has a list of costs for each item separated by new lines (\\n). `budget_items.txt` has a list of the items that were bought. Luckily they are both in order. You need to write a program that will take the files and a value for the overall budget and print out the total spent and how close they are to reaching the budget. In step 2 you will create a new file where the items and prices are in the same document and there is a sum printed out at the end.\n",

+    "## Step 1\n",
+    "1. Create a function called file_to_float_list that takes in a file and returns a list containing a float for each line **Hint** Make sure to remove the newlines when casting as floats.\n",
+    "2. Store the budget of 2000.00 in a variable called budget.\n",
+    "3. Run file_to_float_list on budget_prices.txt and save the result in a variable called prices.\n",
+    "4. Calculate the sum of the prices array and store in a variable called spent.\n",
+    "5. Calculate the percentage of budget spent and store in a variable called percent_spent\n",
+    "6. Print out the results:\n",
+    "\n",
+    "    Budget: 2000.00 Spent: (amt spent) Percentage Spent: (percent spent)\n",
+    "\n",
+    "7. ** Bonus ** Print out a progress bar for the budget. Print out = for every 10% spent and - for every 10% unspent.  =====>-----\n",
+    "\n",
+    "## Step 2\n",
+    "1. Create a function called file_to_string_list that takes in a file and returns a list containing a string for each line with newlines removed.\n",
+    "2. Run file_to_string_list on budget_items.txt and save the result in a variable called stuff_bought.\n",
+    "3. Zip stuff_bought and prices together and store in a varible called  items_and_prices\n",
+    "4. Loop through items and prices and print out the item, then a tab character '\\t' and then the price (use string formatting)\n",
+    "5. Print another line 'Sum\\t(amount spent)'\n",
+    "6. Print a final line 'Budget\\t(budget)'\n",
+    "\n",
+    "7. **Bonus** Print everything you printed for step 2 into a new file. (Then try to open the file in excel.)"
