+## Glee Installation
+
+Before installing Glee into your project, make sure you have pre-installed NPM, NodeJs and [AsyncAPI CLI](https://github.com/asyncapi/cli) tools on your system.
+
+The best way to get started with Glee is by using AsyncAPI CLI, which sets up everything automatically for you. 
+To create a project, run:
+
+```sh
+asyncapi new glee
+```
+
+> For more information on how to install the AsynAPI CLI, you can review the [CLI installation guide](https://www.asyncapi.com/docs/tools/cli/installation).
+
+On installation, you'll find next steps after your project created:
+
+```
+Your project "project" has been created successfully!
+
+Next steps:
+
+  cd project
+  npm install
+  npm run dev
+
+Also, you can already open the project in your favorite editor and start tweaking it
+```
+
+While making twists to your application, you can follow along with our getting started guide on the relevant page.

+
+Glee as a spec-driven framework, makes it easier to work with applications in generating documentation and running the development server.
+
+By following the below json config from `package.json`, let's understand the usage of glee defined under `scripts` object.
+
+```js
+{
+  "scripts": {
+    "docs": "glee docs",
+    "dev": "glee dev",
+    "start": "glee start",
+  }
+}
+```
+These scripts refer to the different stages of developing an application.
+
+`glee docs`: This script generates documentation for your project using the "Glee" documentation tool. This documentation includes information about your project's APIs, modules, and usage instructions.
+
+`glee dev`: This script is used for starting a development server. It launches a local development server, build your project in development mode, or perform other development-related tasks.
+
+`glee start`: This script is responsible for starting your project or application. It is used to launch a production-ready server or application instance.
+
+To get more familiar with these scripts on how they are configured, next dive into our getting started guide.
