## Running the Examples
-To execute these examples utilizing JAXsim with hardware acceleration, there are a couple of options available:
-
-### Option 1: Google Colab (Recommended)
-
-The simplest way to run the examples is by accessing the provided Google Colab notebook link mentioned above. This will enable you to execute the examples in a hosted environment.
-
-### Option 2: Local Execution with `pixi`
-
-For local execution, follow these steps:
+To execute these examples utilizing JAXsim with hardware acceleration, you can use [pixi](https://pixi.sh) to run the examples in a local environment:
1. **Install `pixi`:**
