 ## Installation
 
-Under active development. Coming to `PyPI` soon. Currently you can run `datasetGPT` by cloning this repository as described [here](#contributing).
+```
+pip install datasetGPT
+```
+
+Most of the generation features rely on third-party APIs. Install their respective packages:
+
+```
+pip install openai cohere petals
+```
 
 ## Usage examples
 
 ### Inference LLMs at scale
 
 ```bash
+export OPENAI_API_KEY="..."
+export COHERE_API_KEY="..."
+
 datasetGPT texts \

 ## Contributing
 
+> Still under active development.
+
 Contributions will be highly appreciated. Currently these features are under development:
 - [x] `datasetGPT conversations` - Make two ChatGPT agents talk with one another and record the conversation history.
 - [x] `datasetGPT texts` - Inference different LLMs with a given input prompt and generate multiple outputs by varying parameters.
