-**Notation is an open source toolkit for building serverless applications.**<br />
-It pairs scalable, managed infrastructure with a first-class developer experience.
+## Features
+
+### Infrastructure compiler
 
-<br />
+Generates cloud platform wiring from intuitive application-like code.
+
+Uses inference and best practices to compile policy documents, ARN strings, IAM roles, permissions etc.

-## What's in the toolkit?
+<br />
+
+### Hot infra replacement
+
+Deploys both production and ephemeral dev stacks.
+
+Built from the ground up and designed for fast iteration cycles, hot infra replacement updates live dev stacks while you code.

-## Features
-
-### 🤖 Infrastructure Compiler
-
-- Generates cloud-specific implementation details
-- Uses inference and best practices to compile policy documents, ARN strings, IAM roles, permissions etc.
-
-### 🧩 Serverless Providers
-
-- A selection of popular serverless resources – e.g. lambda, event bridge, API gateway
-- Resources are fully-typed, making them easy to configure and connect to other resources
-- Type checking even works between infrastructure and runtime modules
-
-### 🚀 Cloud Provisioner
-
-- Deploys production and ephemeral dev stacks
-- Built from the ground up and designed for fast iteration cycles
-- Hot infra replacement updates live dev stacks while you code
