What This Class Covers
- Setting up a Claude project for one business, so its facts are there in every chat.
- Adding your own files: services, service area, policies.
- Writing instructions Claude follows every time, like "never give a price."
- Asking one question that pulls from several files at once.
- Finding an out-of-date file before it puts a wrong answer in front of a customer.
- Keeping the project current when something in your business changes.
Take Claude 101 first. This class uses the same made-up business, Riverbend Lawn Care, and the same habit: you check every answer before you use it.
Four Files for Riverbend Lawn Care
Download all four. They're made up, so you can practice without putting real customer information anywhere. One of them is out of date on purpose.
RIVERBEND LAWN CARE — SERVICES (current) Owner: Dee Service days: Monday, Wednesday, Saturday Services: mowing, edging, blowing off walks and driveways Dee brings her own equipment. Not offered: hedge trimming, leaf removal, tree work. Pricing: Dee quotes after seeing the yard. No set prices are published.
RIVERBEND LAWN CARE — SERVICE AREA (current) Towns served: Riverbend, Millbrook, Oakdale Not served: Cedar Hill, Lake Pines If someone outside the area asks, thank them and say Dee only serves the three towns above.
RIVERBEND LAWN CARE — POLICIES (current) Rain: if it rains on a scheduled day, Dee moves the job to the next service day and texts the customer. Payment: due when the job is done. Cash, check or a payment app. First visit: Dee looks at the yard and gives a quote before any work starts. Contact: customers text Dee; she answers the same day.

Six Lessons
Claude's screens change from time to time. If yours looks a little different, look for the same steps by name.
Make a Home for One Business
A project in Claude is a workspace for one subject. It keeps that business's files, its instructions and its chats together. Everything you add to a project's knowledge is there in every chat you start inside it. Free accounts can make up to five projects.
- Sign in at claude.ai.
- Open Projects from the left side of the screen, then choose + New Project.
- Name it Riverbend Lawn Care. The name and description are for you. Claude doesn't read them.
- Start a chat inside the project and send the prompt below.
Give It Your Files
This is the step that changes everything. Instead of pasting the same facts into every chat, you add them to the project once. Below are four practice files for the made-up business. Download all four. One of them is out of date on purpose; Lesson 5 is about catching it.
- Download the four practice files from the Practice Files section on this page.
- In your project, find the knowledge area and choose + to upload. Add all four files.
- Start a new chat in the project and send the prompt below.
Write Instructions It Follows Every Time
Files hold the facts. Instructions tell Claude how to behave in every chat in the project: the tone to use, what never to do, which file wins. You write them once.
- In your project, choose Set project instructions.
- Paste the instructions in the prompt below, then choose Save instructions.
- Start a new chat and send: "A customer texted: can you come mow Sunday?" Check the reply follows every instruction.
Ask Across Your Files
Now one question can pull from several files at once. That's where a project saves real time: Claude checks the days, the area and the policies together, the way you would.
- Start a new chat in the project.
- Send the prompt below.
- Check each part of the reply against the files yourself: the town, each service, the day, the payment.
Catch the Old File
A project is only as right as its files. The 2025 flyer says Tuesday and Thursday, offers leaf removal and serves Cedar Hill. None of that is true any more. Your instructions told Claude to use only current files, but you should still know how to find a conflict yourself.
- Send the prompt below in a new project chat.
- Compare its list with the files. Did it catch all three conflicts?
- Remove the old flyer from the project's knowledge, or rename it so it's clearly marked old.
Keep It Current
Chats in a project don't remember each other. What carries forward is the project's knowledge. So when something changes in your business, change the file, not just the chat. This is the habit that keeps every answer right.
- Dee now mows Fridays too. Open riverbend-services.txt on your computer, add Friday to the service days and save it.
- In the project, remove the old version of the file and upload the new one.
- Start a new chat and send the prompt below.
Eight Cards, One Class
Tap a card to turn it over. Nothing is scored and nothing is recorded.
Six Questions
Optional, ungraded, never a gate. Nothing is stored. Pick an answer and the reasoning appears.
Where should Dee's service days live so every new chat knows them?
What's the difference between knowledge and instructions?
A customer in Cedar Hill asks for a mow. What should the reply say?
Claude says Dee mows Tuesdays. What's the likely cause?
Dee adds Friday. What's the right fix?
Which is the best habit?
Where It Goes Next
Make one project for your own business this week, with three real files and three rules. The next class in Claudia's Classroom covers handing Claude a longer job and checking the result when it's done.
