Lesson 01: Getting Started with n8n: Interface & Your First Manual Trigger

Hi everyone, welcome to the first post in our n8n Workflow Automation Tutorial series here on QTitHow.com. In this post, we will walk through the n8n interface and create your very first workflow using a Manual Trigger node — the perfect starting point if you are new to n8n for beginners.

What You Will Learn

By the end of this post, you will know how to open the n8n editor, create a new workflow, add a Manual Trigger node, and run it to see your first output. This is Step 1 of our beginner n8n tutorial series, so we are keeping things simple and hands-on.

Before You Start

Make sure you have n8n installed and running locally. You should be able to open it in your browser at http://localhost:5678. If you see the n8n editor load, you are ready to go. If not, please set up n8n first and come back here.

How to do:

  1. Step 1 — Open n8n in your browser

    Go to http://localhost:5678 in your browser. You will see the n8n dashboard with a list of your workflows (empty for now). This is your main workspace for building n8n workflow automation.

  2. Step 2 — Create a new workflow

    Click the + New Workflow button in the top right corner. A blank canvas will open. This is where you will build and connect your nodes. Now click the workflow title at the top (it usually says something like "My workflow") and rename it to T1-B1-Hello-n8n. Using a clear name like this helps you stay organized as your workflow list grows.

  3. Step 3 — Add a Manual Trigger node

    Click the + button in the center of the canvas or the Add first step prompt. In the node search panel that opens, type Manual Trigger and select it from the results. The Manual Trigger node will appear on your canvas. This node is the starting point of your workflow — it tells n8n to run the workflow when you click a button manually, instead of on a schedule or from an outside event.

    One important thing to understand right away: the Manual Trigger node only has an OUTPUT connection. It has no INPUT. That makes sense because it is the very first node — there is nothing coming before it.

  4. Step 4 — Execute the workflow

    Click the Execute Workflow button at the bottom of the canvas (or the Test workflow button, depending on your n8n version). The workflow will run immediately. You will see a small green checkmark appear on the Manual Trigger node, which means it executed successfully.

  5. Step 5 — Read the output

    Click on the Manual Trigger node to open its detail panel. Go to the OUTPUT tab. You will see the result looks like this: [{}]. That means the node produced one item, and that item is empty (no data fields inside it yet).

    This brings up a key concept in n8n: the item. An item is the basic unit of data in n8n. Every node receives items, does something with them, and passes items to the next node. Right now your Manual Trigger produces exactly one empty item — just a signal that says "go". Later nodes will fill those items with real data.

  6. Step 6 — Save your workflow

    Click the Save button in the top right corner to save your workflow. Good habit to save early and often.

Key Concept: What Is an Item in n8n?

If you are new to n8n for beginners, the concept of an item is one of the most important things to understand early. Think of an item as one row of data — like one row in a spreadsheet. When the Manual Trigger runs, it sends out one empty item represented as {}. As your workflow grows, nodes like HTTP Request or a database query can return many items at once, and n8n will process each one automatically. We will see this in action in the next post.

What Is Coming Next

In Step 2 of this n8n tutorial series, we will connect an HTTP Request node after the Manual Trigger and call a real API to pull actual data. We will also add an Edit Fields (Set) node to shape that data — and you will see n8n's built-in iteration in action when it automatically processes multiple items at once. Stay tuned.

Conclusion:

You just created your first workflow in n8n, added a Manual Trigger node, ran it, and understood what the output [{}] means — one empty item ready to flow into the next node. That is a solid foundation for everything else in this n8n workflow automation series.
