 # Introduction
 
-🤘 Logto is an open-source customer identity solution.
+🤘 Logto helps you quickly focus on everything after signing in with the following components:
+
+- All-platform user sign-in / sign-up experience with SDK support (SPA, iOS and Android)
+- Passwordless (SMS / Email) support
+- Out-of-box social sign in support (GitHub, Google, WeChat, Alipay, etc.)
+- A web UI to control all above (Admin Console)
+- Extendable multi-language support
+- Easy deployment
+
+Boringly, we call it "[customer identity access management](https://en.wikipedia.org/wiki/Customer_identity_access_management)" or "customer identity solution".
+
+# Get Started
+
+## Prerequisites
+
+- NodeJS >= 16.0.0
+- PostgreSQL >= 14.0.0
+
+It's okay that your PostgreSQL instance is not in the same machine as NodeJS (e.g. containers + remote database environment).
+
+## Run Logto
+
+### Download Script
+
+In your terminal:
+
+```bash
+node -e "$(printf "%s" "$(curl -fsSL https://raw.githubusercontent.com/logto-io/logto/master/install.js)")"
+```
+
+The script will download Logto and create a directory `logto` in the location you ran it.
