# System requirement

### Project Requirement

First make sure you have installed node.js 8.X and npm 5.X version. You can check it on own terminal window simply by entering node -v and npm -v . You can also download latest nodeJs from [here](https://nodejs.org/en/)

```
$ npm -v 
$ node -v 
```

{% hint style="info" %}
once node and npm gets  installed  on your machine we need to install  Ionic globally as well . 
{% endhint %}

```
// You can install ionic globally on your machine 
npm install -g @angular/cli 
```

Once Angular CLI install successfully verify installation with this command 

```
ng -v   // it will show you the version of angualr-cli on your machine.
```

You might receive some other git related Error or node-sass as well . 

If you Get this error please check if [git](https://git-scm.com/) has  installed  on your machine and if you are window user git should be  in your path of machine . 

If there is any error related to [node-saas](https://github.com/sass/node-sass) you may follow their  guide based on your machine OS and most of the case window user might face issue then you can install Python 2.X on your machine and it probably resolves  your Error.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionicfirebaseapp.com/flutter-multirestaurant-app/system-requirement.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
