-This is a ready-to-fork, example/demo project demonstrating how to use [Pinecone Scala](https://github.com/cequence-io/pinecone-scala) with embeddings from [OpenAI Scala Client](https://github.com/cequence-io/openai-scala-client).
+This is a ready-to-fork, example/demo project demonstrating how to use [Pinecone](https://github.com/cequence-io/pinecone-scala) with [OpenAI Scala Client](https://github.com/cequence-io/openai-scala-client) embeddings in Scala using two clients: [Pinecone](https://github.com/cequence-io/pinecone-scala) and [OpenAI Scala Client](https://github.com/cequence-io/openai-scala-client).
 
-Follwing examples are available::
+The demo app can be found in [PineconeOpenAIDemo](./src/main/scala/io/cequence/pineconeopenai/demo/PineconeOpenAIDemo.scala).
+The following env. variables are expected:
+- `PINECONE_SCALA_CLIENT_API_KEY`
+- `PINECONE_SCALA_CLIENT_ENV`
+- `OPENAI_SCALA_CLIENT_API_KEY`
+- `OPENAI_SCALA_CLIENT_ORG_ID` (optional)
 
-TODO
+**✔️ Important**: The demo uses data from [Trec dataset](https://cogcomp.seas.upenn.edu/Data/QA/QC/) created by Cognitive Computation Group at University of Pennsylvania, which we hereby acknowledge. Its training part is included in this project at [trec-train.json](./src/main/resources/trec-train.json) (downloaded using [this script](./src/main/resources/download-trec.sh)).
