+The Tekton CLI, `tkn`, is a command-line interface for Tekton Pipelines. It allows you to create, manage, and interact with Tekton resources such as tasks, pipelines, and pipeline runs from your terminal.
+
+Tekton CLI is available for macOS and Linux and supports the Arm architecture.
+
+## What should I consider before installing the Tekton CLI?
+
+This article provides a quick way to install the latest version of the Tekton CLI for Ubuntu on Arm and macOS with Apple Silicon.
+
+Confirm you are using an Arm computer by running:
+
+```bash { target="ubuntu:latest" }
+uname -m
+```
+
+If you are on Arm Linux the output should be:
+
+```output
+aarch64
+```
+
+If you are on macOS with Apple Silicon the output should be:
+
+```output
+arm64
+```
+

+
+## How do I get started with the Tekton CLI?
+
+To use the Tekton CLI effectively, you need access to a Kubernetes cluster with Tekton Pipelines installed. You can check if Tekton is available in your cluster:
+
+```console
+tkn pipeline list
+```
+
+If Tekton Pipelines is not installed, you might see an error message. In that case, you need to install Tekton Pipelines on your cluster first.
+
+### Common Tekton CLI commands
+
+Below are some common commands to get you started.
+
+List pipelines:
+
+```console
+tkn pipeline list
+```
+
+List pipeline runs:
+
+```console
+tkn pipelinerun list
+```
+
+List tasks:
+
+```console
+tkn task list
+```
+
+List task runs:
+
+```console
+tkn taskrun list
+```
+
+Start a pipeline:
+
+```console
+tkn pipeline start <pipeline-name>
+```
+
+Show pipeline run logs:
+
+```console
+tkn pipelinerun logs <pipelinerun-name>
+```
+
+Describe a pipeline:
+
+```console
+tkn pipeline describe <pipeline-name>
+```
+
+You are now ready to use the Tekton CLI to manage your CI/CD pipelines with Tekton Pipelines on Kubernetes or OpenShift.
