 CloudServer provides a single AWS S3 API interface to access multiple
 backend data storage both on-premise or public in the cloud.
 
-This repository contains a fork of CloudServer with [Vitastor](https://git.yourcmc.ru/vitalif/vitastor)
+CloudServer is useful for Developers, either to run as part of a
-backend support.
+continous integration test environment to emulate the AWS S3 service locally
+or as an abstraction layer to develop object storage enabled
+application on the go.
 
-## Quick Start with Vitastor
+## Learn more at [www.zenko.io/cloudserver](https://www.zenko.io/cloudserver/)
 
-Vitastor Backend is in experimental status, however you can already try to
+## [May I offer you some lovely documentation?](http://s3-server.readthedocs.io/en/latest/)
-run it and write or read something, or even mount it with [GeeseFS](https://github.com/yandex-cloud/geesefs),
-it works too 😊.
 
-Installation instructions:
+## Docker
 
-### Install Vitastor
+[Run your Zenko CloudServer with Docker](https://hub.docker.com/r/zenko/cloudserver/)
 
-Refer to [Vitastor Quick Start Manual](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/intro/quickstart.en.md).
+## Contributing
 
-### Install Zenko with Vitastor Backend
+In order to contribute, please follow the
+[Contributing Guidelines](
+https://github.com/scality/Guidelines/blob/master/CONTRIBUTING.md).
 
-- Clone this repository: `git clone https://git.yourcmc.ru/vitalif/zenko-cloudserver-vitastor`
+## Installation
-- Install dependencies: `npm install --omit dev` or just `npm install`
-- Clone Vitastor repository: `git clone https://git.yourcmc.ru/vitalif/vitastor`
-- Build Vitastor node.js binding by running `npm install` in `node-binding` subdirectory of Vitastor repository.
-  You need `node-gyp` and `vitastor-client-dev` (Vitastor client library) for it to succeed.
-- Symlink Vitastor module to Zenko: `ln -s /path/to/vitastor/node-binding /path/to/zenko/node_modules/vitastor`
 
-### Install and Configure MongoDB
+### Dependencies
 
-Refer to [MongoDB Manual](https://www.mongodb.com/docs/manual/installation/).
+Building and running the Zenko CloudServer requires node.js 10.x and yarn v1.17.x
+. Up-to-date versions can be found at
+[Nodesource](https://github.com/nodesource/distributions).
 
-### Setup Zenko
+### Clone source code
 
-- Create a separate pool for S3 object data in your Vitastor cluster: `vitastor-cli create-pool s3-data`
+```shell
-- Retrieve ID of the new pool from `vitastor-cli ls-pools --detail s3-data`
+git clone https://github.com/scality/S3.git
-- In another pool, create an image for storing Vitastor volume metadata: `vitastor-cli create -s 10G s3-volume-meta`
-- Copy `config.json.vitastor` to `config.json`, adjust it to match your domain
-- Copy `authdata.json.example` to `authdata.json` - this is where you set S3 access & secret keys,
-  and also adjust them if you want to. Scality seems to use a separate auth service "Scality Vault" for
-  access keys, but it's not published, so let's use a file for now.
-- Copy `locationConfig.json.vitastor` to `locationConfig.json` - this is where you set Vitastor cluster access data.
-  You should put correct values for `pool_id` (pool ID from the second step) and `metadata_image` (from the third step)
-  in this file.
-
-Note: `locationConfig.json` in this version corresponds to storage classes (like STANDARD, COLD, etc)
-instead of "locations" (zones like us-east-1) as it was in original Zenko CloudServer.
-
-### Start Zenko
-
-Start the S3 server with: `node index.js`
-
-If you use default settings, Zenko CloudServer starts on port 8000.
-The default access key is `accessKey1` with a secret key of `verySecretKey1`.
-
-Now you can access your S3 with `s3cmd` or `geesefs`:
-
-```
-s3cmd --access_key=accessKey1 --secret_key=verySecretKey1 --host=http://localhost:8000 mb s3://testbucket
 ```
 
-```
+### Install js dependencies
-AWS_ACCESS_KEY_ID=accessKey1 \
+
-    AWS_SECRET_ACCESS_KEY=verySecretKey1 \
+Go to the ./S3 folder,
-    geesefs --endpoint http://localhost:8000 testbucket mountdir
+
+```shell
+yarn install --frozen-lockfile
 ```

+```shell
+yarn cache clean
+```
+
+## Run it with a file backend
+
+```shell
+yarn start
+```
+
+This starts a Zenko CloudServer on port 8000. Two additional ports 9990 and
+9991 are also open locally for internal transfer of metadata and data,
+respectively.
+
+The default access key is accessKey1 with
+a secret key of verySecretKey1.
+
+By default the metadata files will be saved in the
+localMetadata directory and the data files will be saved
+in the localData directory within the ./S3 directory on your
+machine.  These directories have been pre-created within the
+repository.  If you would like to save the data or metadata in
+different locations of your choice, you must specify them with absolute paths.
+So, when starting the server:
+
+```shell
+mkdir -m 700 $(pwd)/myFavoriteDataPath
+mkdir -m 700 $(pwd)/myFavoriteMetadataPath
+export S3DATAPATH="$(pwd)/myFavoriteDataPath"
+export S3METADATAPATH="$(pwd)/myFavoriteMetadataPath"
+yarn start
+```
+
+## Run it with multiple data backends
+
+```shell
+export S3DATA='multiple'
+yarn start
+```
+
+This starts a Zenko CloudServer on port 8000.
+The default access key is accessKey1 with
+a secret key of verySecretKey1.
+
+With multiple backends, you have the ability to
+choose where each object will be saved by setting
+the following header with a locationConstraint on
+a PUT request:
+
+```shell
+'x-amz-meta-scal-location-constraint':'myLocationConstraint'
+```
+
+If no header is sent with a PUT object request, the
+location constraint of the bucket will determine
+where the data is saved. If the bucket has no location
+constraint, the endpoint of the PUT request will be
+used to determine location.
+
+See the Configuration section in our documentation
+[here](http://s3-server.readthedocs.io/en/latest/GETTING_STARTED/#configuration)
+to learn how to set location constraints.
+
+## Run it with an in-memory backend
+
+```shell
+yarn run mem_backend
+```
+
+This starts a Zenko CloudServer on port 8000.
+The default access key is accessKey1 with
+a secret key of verySecretKey1.
+
+## Run it with Vault user management
+
+Note: Vault is proprietary and must be accessed separately.
+
+```shell
+export S3VAULT=vault
+yarn start
+```
+
+This starts a Zenko CloudServer using Vault for user management.
