+
+## 🐍 Python and Pip
+To follow the steps in this guide, you'll need:
+
+1. Install [Python](https://wiki.python.org/moin/BeginnersGuide/Download/). We support Python 3.11 to 3.13.
+2. Install [pip](https://pip.pypa.io/en/stable/installation/) - a Python package installer
+
+
+## 🌴 Install CocoIndex
+```bash
+pip install cocoindex
+```
+
+## 📦 Install Postgres
+
+You can skip this step if you already have a Postgres database with pgvector extension installed. 
+
+If you don't have a Postgres database:
+
+1. Install [Docker Compose](https://docs.docker.com/compose/install/) 🐳.
+2. Start a Postgres SQL database for cocoindex using our docker compose config:
+
+```bash
+docker compose -f <(curl -L https://raw.githubusercontent.com/cocoindex-io/cocoindex/refs/heads/main/dev/postgres.yaml) up -d
+```
+
+## 🎉 All set!
+
+You can now start using CocoIndex.
