ReadMe need to update for not using azd up #93
Description
If you are not using azd up, you need to create a .env file with the following content:
AZURE_OPENAI_ENDPOINT=<your instance name>.openai.azure.com
AZURE_OPENAI_REALTIME_DEPLOYMENT=gpt-4o-realtime-preview
AZURE_OPENAI_REALTIME_VOICE_CHOICE=<choose one: echo, alloy, shimmer>
AZURE_OPENAI_API_KEY=<your api key>
AZURE_SEARCH_ENDPOINT=https://<your service name>.search.windows.net
AZURE_SEARCH_INDEX=<your index name>
AZURE_SEARCH_API_KEY=<your api key>
Make sure to remove wss:// from the AZURE_OPENAI_ENDPOINT so it appears as .openai.azure.com.
