update dashboard description

In preparation of the 0.3.0 release, I want to update the dashboard.
At the present, it displays the contents of the README with installation
instructions which are likely confusing users since the extension has
already been installed.

The new text is not perfect and does not fully address containers#624 but I think
it's a step in the right direction.  The descriptions will very likely
need polishing in the future.  I did not find a way to create links that
allow for opening another menu.  For instance, it would be nice to have
clickable links/buttons that navigate users directly into the specific
menu such as the Recipes Catalog.

Some graphical elements (e.g., screenshots) may be a nice additions as
well.  We can add them later on, if needed, when the UI has settled a
bit more.

-# AI studio
+# Welcome to AI Studio
 
-## Installing a released version
+The Podman Desktop AI Studio extension simplifies getting started and develop with AI in a local environment. It provides key open-source technologies to start building on AI. A curated catalog of so-called recipes helps navigate the jungle of AI use cases and AI models. AI Studio further ships playgrounds: environments to experiment with and test AI models, for instance, a chat bot.
 
-If you want to install a specific version of the extension, go to Podman Desktop UI > ⚙ Settings > Extensions > Install a new extension from OCI Image.
+## Recipes Catalog
 
-The name of the image to use is `ghcr.io/projectatomic/ai-studio:version_to_use`.
+AI Studio ships with a so-called Recipes Catalog that helps you navigate a number of core AI use cases and problem domains such as Chat Bots, Code Generators and Text Summarizers. Each recipe comes with detailed explanations and sample applications that can be run with various large language models (LLMs). Experimenting with multiple models allows finding the optimal one for your use case.
 
-You can get released tags for the image at https://github.com/projectatomic/studio-extension/pkgs/container/ai-studio.
+## AI Models
 
-The released tags follow the major.minor.patch convention.
+AI Studio provides a curated list of open source AI models and LLMs. Once downloaded, the models are available to be used for AI applications, model services and playgrounds.
 
-If you want to install the last release version, use the latest tag.

-
-## Packaging sample applications
-
-Sample applications may be added to the catalog. See [packaging guide](PACKAGING-GUIDE.md) for detailed information.

-## Feedback
-
-You can provide your feedback on the extension with [this form](https://forms.gle/tctQ4RtZSiMyQr3R8) or create [an issue on this repository](https://github.com/projectatomic/studio-extension/issues).
+The integrated Playground environments allow for experimenting with available models in a local environment. An intuitive user prompt helps in exploring the capabilities and accuracy of various models and aids in finding the best model for the use case at hand.
