 First of all we need a Schema. Each schema maps to a MongoDB collection. It defines the shape of the documents within that collection. Schemas are building block for Models. They can be nested to create complex models, but in this case we'll keep things simple. A model allows you to create instances of your objects, called documents.
 
-Repl.it is a real server, and in real servers the interactions with the database happen in handler functions. These functions are executed when some event happens (e.g. someone hits an endpoint on your API). We’ll follow the same approach in these exercises. The `done()` function is a callback that tells us that we can proceed after completing an asynchronous operation such as inserting, searching, updating, or deleting. It's following the Node convention, and should be called as `done(null, data)` on success, or `done(err)` on error.

-In this challenge, you will import the required projects, and connect to your Atlas database.
+Working on these challenges will involve you writing your code using one of the following methods:
+
+- Clone [this GitHub repo](https://github.com/freeCodeCamp/boilerplate-mongomongoose/) and complete these challenges locally.
+- Use [our Replit starter project](https://replit.com/github/freeCodeCamp/boilerplate-mongomongoose) to complete these challenges.
+- Use a site builder of your choice to complete the project. Be sure to incorporate all the files from our GitHub repo.
+
+When you are done, make sure a working demo of your project is hosted somewhere public. Then submit the URL to it in the `Solution Link` field.
+
+In this challenge, you will set up a MongoDB Atlas database and import the required packages to connect to it.
+
+Follow <a href='https://www.freecodecamp.org/news/get-started-with-mongodb-atlas/' rel='noopener noreferrer' target='_blank'>this tutorial</a> to set up a hosted database on MongoDB Atlas.

-Add `mongodb` and `mongoose` to the project’s `package.json`. Then, require mongoose as `mongoose` in `myApp.js`. Store your MongoDB Atlas database URI in a private `.env` file as `MONGO_URI`. Surround the the URI with single or double quotes, and make sure no space exists between both the variable and the `=`, and the value and `=`. Connect to the database using the following syntax:

Its value should be your MongoDB Atlas database URI. Be sure to surround the URI with single or double quotes, and remember that you can't use spaces around the `=` in environment variables. For example, `MONGO_URI='VALUE'`. When you are done, connect to the database using the following syntax:
 
 ```js
 mongoose.connect(<Your URI>, { useNewUrlParser: true, useUnifiedTopology: true });
