+This [image](https://hub.docker.com/r/naskio/n8n-python) includes Python 3.10 by default. it can be used to run python
+scripts inside n8n using the [Execute Command](https://docs.n8n.io/nodes/n8n-nodes-base.executeCommand/) node or code
+snippets using the custom node [Python Function](https://www.github.com/naskio/n8n-nodes-python).

-n8n is an extendable workflow automation tool. With a [fair-code](http://faircode.io) distribution model, n8n will
-always have visible source code, be available to self-host, and allow you to add your own custom functions, logic and
-apps. n8n's node-based approach makes it highly versatile, enabling you to connect anything to everything.
-
-This [image](https://hub.docker.com/r/naskio/n8n-python) includes Python 3.10 by default. it can be used to run python
-code using the [Execute Command](https://docs.n8n.io/nodes/n8n-nodes-base.executeCommand/) node.
-
-## Example
+## Image Setup
 
 Using docker compose
 [docker-compose.yml](./demo/docker-compose-local.yml)
 
+## Usage
+
+### Run Python Code
+
+The image includes the custom module [n8n-nodes-python](https://www.github.com/naskio/n8n-nodes-python) by default.
+
+We can use this custom node [Python Function](https://www.github.com/naskio/n8n-nodes-python) to run a python code over
+the `items` (works the same way as [Function](https://docs.n8n.io/nodes/n8n-nodes-base.function) node)
+
+[Python Function node docs](https://www.github.com/naskio/n8n-nodes-python)
+
+### Run mounted Python scripts using the ExecuteCommand node
+
+You can run `*.py`files that has been mounted to the container using
+the [ExecuteCommand](https://docs.n8n.io/nodes/n8n-nodes-base.executeCommand/) node.
+
+### Installing external packages
+
+The [ExecuteCommand](https://docs.n8n.io/nodes/n8n-nodes-base.executeCommand/) node can be used to install python
+packages or install dependencies from a mounted `requirements.txt` file to the container.
+
+It can be combined with [n8nTrigger](https://docs.n8n.io/nodes/n8n-nodes-base.n8nTrigger) to install packages directly
+after starting the container.
+
+> Once the packages are installed, it can be used in the Python Function node. `import <package>`
