+# Slack Websocket API
+
+This Slack Websocket API leverages the AsyncAPI specification to connect Slack with OpenAI's AI models. When a user reacts to a message on Slack, this API sends the reaction to OpenAI's server. ChatGPT then crafts a fun response, which is posted as a reply to the message thread on Slack.

+- [Usage](#usage)
+- [Environment Variables](#environment-variables)
+
+## Overview
+
+The API listens for reaction events in Slack, processes them through OpenAI's API to generate responses, and sends those back to Slack as a threaded message.
+
+## Prerequisites
+
+- Node.js (version 12 or higher)
+- A Slack app with permissions to read reactions and post messages
+- Access to OpenAI API
+
+## Configuration
+
+Before running the project, you must update the `asyncapi.yaml` file with the current `ticket` and `app_id` for the Slack WebSocket connection:
+
+```yaml
+channels:
+  SlackEventStream:
+    address: /link/?ticket=[ticket]&app_id=[app_id]
+```
+
+Replace `[ticket]` and `[app_id]` with the respective values for your Slack app.
+
+## Usage
+
+Set the environment variables by creating a `.env` file in the root of the project:
+
+```plaintext
+SLACK_HTTP=xoxb-**********
+CHAT_API=openai_token
+```
+
+Start the API server with:
+
+```sh
+npm run dev
+```
+
+The API will now listen for Slack reaction events, interact with OpenAI, and post responses on Slack.
+
+## Environment Variables
+
+The following environment variables are necessary for the API to function:
+
+- `SLACK_HTTP`: Your Slack app's OAuth token.
+- `CHAT_API`: Your OpenAI API key.
+
+Ensure these are set in your environment.
