Followup to #7566 | Story: https://linear.app/n8n/issue/PAY-926 ### Manual workflow activation and deactivation In a multi-main scenario, if the user manually activates or deactivates a workflow, the process (whether leader or follower) that handles the PATCH request and updates its internal state should send a message into the command channel, so that all other main processes update their internal state accordingly: - Add to `ActiveWorkflows` if activating - Remove from `ActiveWorkflows` if deactivating - Remove and re-add to `ActiveWorkflows` if the update did not change activation status. After updating their internal state, if activating or deactivating, the recipient main processes should push a message to all connected frontends so that these can update their stores and so reflect the value in the UI. ### Workflow activation errors On failure to activate a workflow, the main instance should record the error in Redis - main instances should always pull activation errors from Redis in a multi-main scenario. ### Leadership change On leadership change... - The old leader should stop pruning and the new leader should start pruning. - The old leader should remove trigger- and poller-based workflows and the new leader should add them. |

📺 Here's a 📺 short video (< 4 min) that goes over key concepts of creating workflows in n8n.
Getting Started
There are a couple of ways to get started with n8n.
Use npx
To spin up n8n using npx, you can run:
npx n8n
It will download everything that is needed to start n8n.
You can then access n8n by opening: http://localhost:5678
Note: The minimum required version for Node.js is v14.15. Make sure to update Node.js to v14.15 or above.
Run with Docker
To play around with n8n, you can also start it using Docker:
docker run -it --rm \
--name n8n \
-p 5678:5678 \
docker.n8n.io/n8nio/n8n
Be aware that all the data will be lost once the Docker container gets removed. To persist the data mount the ~/.n8n folder:
docker run -it --rm \
--name n8n \
-p 5678:5678 \
-v ~/.n8n:/home/node/.n8n \
docker.n8n.io/n8nio/n8n
Refer to the documentation for more information on the Docker setup.
Install with npm
To install n8n globally using npm:
npm install n8n -g
After the installation, start n8n running the following command:
n8n
# or
n8n start
Sign-up on n8n.cloud
Sign-up for an n8n.cloud account.
While n8n.cloud and n8n are the same in terms of features, n8n.cloud provides certain conveniences such as:
- Not having to set up and maintain your n8n instance
- Managed OAuth for authentication
- Easily upgrading to the newer n8n versions
Available integrations
n8n has 280+ different nodes that allow you to connect various services and build your automation workflows. You can find the list of all the integrations at https://n8n.io/integrations
Documentation
To learn more about n8n, refer to the official documentation here: https://docs.n8n.io
You can find additional information and example workflows on the n8n.io website.
Create Custom Nodes
You can create custom nodes for n8n. Follow the instructions mentioned in the documentation to create your node: Creating nodes

What does n8n mean, and how do you pronounce it?
Short answer: n8n is an abbreviation for "nodemation", and it is pronounced as n-eight-n.
Long answer: In n8n, you build your automation ("-mation") workflows by connecting different nodes in the Editor UI. The project is also built using Node.js. As a consequence, the project was named nodemation.
However, the name was long, and it wouldn't be a good idea to use such a long name in the CLI. Hence, nodemation got abbreviated as "n8n" (there are eight characters between the first and the last n!).
