 # View Parquet files on Hugging Face
 
-This app allows you to view Parquet files hosted in a Hugging Face dataset. It hardcoded for now: https://huggingface.co/datasets/codeparrot/github-code/resolve/main/data/train-00000-of-01126.parquet
+This app allows you to view any file hosted in a Hugging Face dataset. You can search for a dataset, browse its files, and view them as:
+- a table if the file is Parquet
+- an image if the file is an image
+- an HTML page if the file is Markdown
+- plain text otherwise.
 
-The app is static and is currently deployed with a [GitHub Action](./github/workflows/ci.yml) to a Hugging Face space: https://huggingface.co/spaces/severo/parquet-viewer.
+It's particularly useful to view Parquet files.
+
+You can login with your Hugging Face account to view private datasets.
