Step 1: Create a new Phoenix app

Type this in the terminal:

mix test_app

The command’s output is a list of the files it creates, which will be fairly long. We’ll go into detail about what these files are later.

Then it will ask you to fetch and install dependencies, type Y to do this. If there’s an error at this point, grab a volunteer to help you.

Change into the project directory:

cd test_app

Step 2: Get Dependencies

Type the following into your terminal:

mix deps.get

Step 6: Install nm and node

npm install && node node_modules/brunch/bin/brunch build

Step 3: Create the database

Type this in a terminal:

mix ecto.create

Then, type this in a terminal:

mix phoenix.server

If phoenix server starts up with no errors, you’re golden! It’ll look something like this:
