When learning a new language or framework, identifying the right resources could be difficult, relying on the documentation is your best bet. It provides the basic knowledge to get you started.

> Manuals are the most important documents no one read
> _- Lot of Us._

But for most developers, documentation could be difficult to understand or too large to read.

Angular has one of the most detailed documentation I have read, the team did a great job simplifying it.

In this post, I will explain how I read and got the most out of Angular's documentation, the pattern that helped me and I hope it will help you.

### The Structure.

Angular's Documentation is structured to take you from a beginner to an Angular developer.

On Angular's official page [angular.io](https://angular.io), click on **Get Started**.

#### The Document's table of contents.

To view the Documentation's Table of Contents, click on the burger menu at the top left of the screen, a navigation menu will slide out.

Let's talk about them.

- **Getting Started**
The Getting Started section will guide you on setting up your Angular environment, installation of other software used by Angular, and a first Angular application.

- **Tutorial**
The Tutorial section will walk you through building a full functional Angular application, with some code along examples to provide you with production-ready Angular skills.

- **Fundamentals**
The Fundamentals section explains the features and the architect behind Angular's build block, how Angular is structured around these features and how these features can help you write better codes.

- **Techniques**
The Techniques section describes the Angular's added features and implementation, including how to use first/third party libraries and features.

- **Setup and Deployment**
The Setup and Deployment section describes the file structure, environment configuration, other concepts like the general life-circle of an application, and how your application interacts with the browser.

- **Release Information**
The Release Information section explains why Angular is frequently updated by the community. When to expect a major release of the framework, plus what features to expect including how to update your application to the latest version.

- **Quick References**
Other information you will need, code style guides and definition of terms used through the documentation.

- **CLI Commands**
List of CLI commands for Angular CLI, with other flags that increase your productivity.

- **API**
List of all Angular's API with detailed descriptions.

## Navigating
All mentioned above could be overwhelming but don't worry, let me walk you through a secret.

#### Where to go

**First Time with Angular**: you are new to Angular, you've seen an online tutorial or you're are making a framework switch. I recommend you start with _Getting Started_, follow the guide, read through and understand. Follow up with the _Tutorial_ section, code along and practice more after the tutorial.

**WHY**: The getting started section will walk you through scaffolding your application, it will explain the basic process, how to install the Angular CLI and how to start or initiate an Angular project. This is a fundamental instruction as a beginner. <br>
The tutorial section will provide you with a functional application that covers the most important parts of building application with Angular, syntax and features that will give you the basic knowledge of Angular.

**Moving Forward**: Next I recommend you navigate to _Fundamentals_, you do not need to do a code along in this section. Read through to understand, this will open you up to see Angular under the hood, it is literally the Aha section.

**WHY**: The team focused on explaining how each component of the framework interacts with one another, the concept behind the framework's features and how it was structured to give developers flexibility and power to build applications. While I was reading this section it felt like a Dan Brown's Novel 😊😊.

**Now Breaking the Chain**: Jump four steps to the _CLI Commands_ section, read it topic by topic like a reference list, practice each topic, _not important_ but you get to see what these commands can do.

**WHY**: At this stage, during your tutorial/practice you've used some of these commands, this section provides you a detailed explanation of each command plus some you didn't even know existed, including possible flags you can pass through. When done, you will be writing CLI commands like an Angular pro.

**Step Back a Little**: Go back to techniques, at this point you are an Angular genius, go forth and build. _May The NGs be with you_. But even geniuses make mistakes and to be a master you must never stop learning. <br> These mistakes may cause a security breach on your application, the Technique section explained the best approach to help with security checks, some _dos and don'ts_. The section will guide you on how to implement some of the latest software development practice like implementing Service Worker for an Angular PWA and many other cool practices.

**Are we still here**: Okay, head to the _Setup and Deployment_ section, this is more of a descriptive section. It describes how to prepare your Angular application for production or development environment, how to test and set up a testing environment and how to produce and deploy your Angular application _aka_ `Hello World!`.

**Save the rest for last**: As I said, "you must never stop learning". The API section is an ocean of knowledge and that is what it should be. My recommendation may be yet my confirmation is that you cannot read the API on a page by page style, even more confusing it is alphabetically arranged. So not to confuse your confusion, you do not need to read this section right way. It should be the section that brings you back to the documentation from time to time.

## Conclusion
Learning a new framework is an exciting journey, and fun when you have the right tools and resources to help you. The way you learn or use these resources can affect the journey. You may have your own way of learning, some learn with video, blogs or physical couching, some don't even need documentation, _"Believe me, they exist 😉"_. I am not enforcing you to follow this guide, it's something that really helped me on my journey. Please if you have any guide that may have helped you on your journey or resources that you feel was helpful, I will be happy to hear about it please share in the comment section, Thank You.
I wish you luck on learning and understanding Angular and again _"May the NGs be with you…"_
