+# Recitation 1 - Git, Github and TypeScript Starter Code
+
+See recitation handout on the [course website](https://cmu-313.github.io/recitations/reci1-github/)
+
+The starter code is a basic express server with an endpoint that computes fibonacci(n)
+
+## Running the App
+
+The steps below aren't strictly necessary to complete the recitation.
+
+1. Make sure you have TypeScript and npm installed
+2. Run `npm install` to install dependencies
+3. Run `npm start` to start the server
+4. Go to a browser and visit `localhost:3000/fib/n` to see the result for fibonacci(n)
+
+## Running tests and linter
+
+We've setup a GitHub action to run eslint and tests for the fibonacci endpoint.
+
+- You can run the linter locally by running `npm run lint`
+- You can run the tests defined in `tests/fib.test.ts` by running `npm run test`
