+## App features
+
+*   Start building pipelines right away
+    * Intuitive visual drag and drop interface
+    * No registration required to build. You own your data.
+*   Execute pipelines on your local machine or in Cloud
+    * Easily install the app on local machine or deploy to cloud
+    * Submit pipelines for execution with a single click.
+    * Easily monitor all pipeline task executions, view the artifacts, read the logs.
+*   Fast iteration
+    * Clone any pipeline run and get a new editable pipeline
+    * Create pipeline -> Submit run -> Monitor run -> Clone run -> Edit pipeline -> Submit run ...
+*   Automatic execution caching and reuse
+    * Save time and compute. Don't re-do what's done
+    * Successful and even running executions are re-used from cache
+*   Reproducibility
+    * All your runs are kept forever (on your machine) - graph, logs, metadata
+    * Re-run an old pipeline run with just two clicks (Clone pipeline, Submit run)
+    * Containers and strict component versioning ensure reproducibility
+*   Pipeline Components
+    * Time-proven `ComponentSpec`/`component.yaml` format
+    * A library of preloaded components
+    * Fast-growing public component ecosystem
+    * Add your own components (public or private)
+    * Easy to create your own components manually or using the Cloud Pipelines SDK
+    * Components can be written in [any language](https://github.com/Ark-kun/pipeline_components/tree/master/components/sample) (Python, Shell, R, Java, C#, etc).
+    * Compatible with [Google Cloud Vertex AI Pipelines](https://cloud.google.com/vertex-ai/docs/pipelines/introduction) and [Kubeflow Pipelines](https://www.kubeflow.org/docs/components/pipelines/introduction/)
+    * Lots of pre-built components on GitHub: [Ark-kun/pipeline_components](https://github.com/Ark-kun/pipeline_components/tree/master/components).

 ## Concepts
 
 A **pipeline system** like Tangle orchestrates containerized command-line programs.
