 # napi
+
+Powerful CLI + UI for inspecting and refactoring an API codebase in any language and web framework.
+
+> This project is under ongoing development. Check the [status section](#status) for more information on supported languages and frameworks.
+
+![demo](https://nanoapi.io/images/video/demo.gif)
+
+## Features
+
+- **Inspect**: Analyze your codebase and understand the API endpoints, middleware, and other API-specific code
+- **Refactor**: Refactor your codebase into smaller, more manageable pieces through the UI or annotations
+- **Build**: Transform your codebase into smaller, more manageable pieces at build time
+
+## Motivation
+
+- Quickly refactor large/monolith codebases into smaller, more manageable pieces at build time
+- Increase robustness by reducing the downtime through isolating
+- Don't waste time with consultants or contractors to refactor your codebase
+- Better understand what your codebase is doing today
+- Create a new development paradigm (develop monolith, deploy microservice) for projects moving fast
+
+To understand better what we mean by the above, please take a look at our [documentation](https://nanoapi.io/docs/nanoapi).
+
+## Design goals
+
+- Zero configuration
+- Support for all languages and web frameworks
+- Auto-detect endpoint definitions, middleware, and other API-specific code without manual annotations
+- Clean, simple, and easy to use UI
+
+# Usage
+
+### Installation
+
+We are working on a binary release, but for now, you can install it via this github repository:
+
+```bash
+$ git clone https://github.com/nanoapi-io/napi.git
+$ cd napi
+$ npm install
+```
+
+### Usage
+
+To open the UI and inspect your codebase, run the following command:
+
+```bash
+$ napi ui /path/to/entrypoint
+```
+
+### Commands:
+```
+  ui [entrypoint]  Inspect the codebase and understand the API endpoints, middleware, and other API-specific code
+  split <entrypoint>    Transform the codebase into smaller, more manageable pieces at build time
+```
+
+## Using the UI
+
+The easiest way to refactor your API endpoints is to do it through our UI. You can group endpoints and create builds from here.
+
+## Building with Annotations
+
+You can also refactor your codebase by adding annotations to your code. Here is an example of how you can do it:
+
+```typescript
+// src/api.js
+
+import * as express from 'express';
+
+import * as service from './service.js';
+
+const app = express();
+const port = 3000;
+
+app.use(express.json());
+
+// @nanoapi endpoint:/api/v2/maths/time method:GET group:Time
+app.get('/api/v2/maths/time', (req, res) => {
+    const result = service.time();
+    return res.json({
+        result
+    });
+});
+
+// @nanoapi endpoint:/api/v2/maths/addition method:POST group:Maths
+app.post('/api/v2/maths/addition', (req, res) => {
+    const { body } = req;
+    const result = service.addition(body.a, body.b);
+    return res.json({
+        result
+    });
+});
+
+// @nanoapi endpoint:/api/v2/maths/subtraction method:POST group:Maths
+app.post('/api/v2/maths/subtraction', (req, res) => {
+    const { body } = req;
+    const result = service.subtraction(body.a, body.b);
+    return res.json({
+        result
+    });
+});
+
+app.listen(port, () => {
+    console.log(`App listening on port: ${port}`);
+});
+```
+
+## Output
+
+From the exmaple above, you will get the following output from running a build:
+
+```typescript
+// dist/Time/src/api.js
+
+import * as express from 'express';
+
+import * as service from './service.js';
+
+const app = express();
+const port = 3000;
+
+app.use(express.json());
+
+app.get('/api/v2/maths/time', (req, res) => {
+    const result = service.time();
+    return res.json({
+        result
+    });
+});
+
+app.listen(port, () => {
+    console.log(`App listening on port: ${port}`);
+});
+```
+
+## Status
+
+This project is in the early stages of development. We are actively working on the project and will be releasing new features and improvements regularly, which may include a rewrite into a more efficient and generic language like Rust or Go. Please check our issues and project board for more information.
