There are two methods to setup vuestorefront.
1: Using CLI installation.
You can install vuestorefront anywhere on server but we preferred it to be resides in magento directory.

1: First install vuestorefront using below command.
	`git clone https://github.com/DivanteLtd/vue-storefront.git vue-storefront`

2: Download all npm packages by executing below command in vue-storefront directory.
	`yarn install`

3: run installer.
	npm run installer

4: In first step you need to provide you magento url.

5: Provide you git variable in most of the cases it will be `git`

6: Path for installing backend locally.
	enter `vue-storefront-api` it will clone api repository in `vue-storefront-api` directory.

7: Path for images endpoint.
	http://localhost:8080/img/

8: It takes some time for installation and after successful installation you can see success screen.

if you see success screen that means.
	- You got Redis and Elastic Search up and running.
	- vue-storefront is up and running on localhost:3000
	- vue-storefront-api us running on localhost:8080

=> Working with local instances.
	Our basic instance are ready and we can move to integrate with local magento instance.
	First you need to install mage2vuestorefront — which is simple. 
	https://github.com/DivanteLtd/mage2vuestorefront

	1: git clone https://github.com/DivanteLtd/mage2vuestorefront.git mage2vs cd mage2vs/src npm install

	2: We need to create a integration for api calling of magento2 default.
		In magento backend go to System -> Integrations then Then click Add new integration and just fill:
		- Name (whatever)
		- your password to confirm the changes,
		- check Catalog, Sales, My Account and Carts on API permissions tab — save

	3: In the result you’ll click Activate and get some oauth access tokens:

	4: Please edit the src/config.js file in your mage2vuestorefront directory and provide magento_url, consumerKey, consumerSecret, accessToken, accessTokenSecret key.
		- The rest of config.js files points out to your vue-storefront-api based Docker and Redis instances which are required by mage2nosql to work.
		- To import all the Products, Categories and other important stuff to your Elastic Search instance you should run the following commands
			node cli.js taxrule
			node cli.js attributes
			node cli.js categories
			node cli.js productcategories
			node cli.js products
		- It’s advisable to run these commands over and over as they’re doing update operation in elastic search.

=>How to restart everything?
	goto vue-storefront directory and run npm run dev
	goto vue-storefront-api directory and run: docker-compose up -d and then npm run dev

2: Manual installation, If above fails for you, you can also do manual steps.

2: clone vuestorefrontapi
	- git clone https://github.com/DivanteLtd/vue-storefront-api.git vue-storefront-api
	- install dependencies using yarn install or npm i

3: copy default config to local config in vue-storefront/config/ and vue-storefront-api/config.

4: create integration for magento2 api call and provide details [token info] in vue-storefront-api/config/local.json

5: go to vuestorefront-api folder and up the docker.
	docker-compose up -d

6: import data of magento2 to elasticsearch.
	-> yarn mage2vs import
	-> varify your data on http://localhost:5601/

7: run below command form vuestorefront and vuestorefront-api
	-> npm run dev

8: open localhost:3000 and varify your site.
