+Vitastor Backend is in experimental status, however you can already try to
+run it and write or read something, or even mount it with [GeeseFS](https://github.com/yandex-cloud/geesefs),
+it works too 😊.
 
-## Docker
+Installation instructions:
 
-[Run your Zenko CloudServer with Docker](https://hub.docker.com/r/zenko/cloudserver/)
+### Install Vitastor
 
-## Contributing
+Refer to [Vitastor Quick Start Manual](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/intro/quickstart.en.md).
 
-In order to contribute, please follow the
+### Install Zenko with Vitastor Backend
-[Contributing Guidelines](
-https://github.com/scality/Guidelines/blob/master/CONTRIBUTING.md).
 
-## Installation
+- Clone this repository: `git clone https://git.yourcmc.ru/vitalif/zenko-cloudserver-vitastor`
+- 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`
 
-### Dependencies
+### Install and Configure MongoDB
 
-Building and running the Zenko CloudServer requires node.js 10.x and yarn v1.17.x
+Refer to [MongoDB Manual](https://www.mongodb.com/docs/manual/installation/).
-. Up-to-date versions can be found at
-[Nodesource](https://github.com/nodesource/distributions).
 
-### Clone source code
+### Setup Zenko
 
-```shell
+- Create a separate pool for S3 object data in your Vitastor cluster: `vitastor-cli create-pool s3-data`
-git clone https://github.com/scality/S3.git
+- Retrieve ID of the new pool from `vitastor-cli ls-pools --detail s3-data`
+- 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 \
-Go to the ./S3 folder,
+    AWS_SECRET_ACCESS_KEY=verySecretKey1 \
-
+    geesefs --endpoint http://localhost:8000 testbucket mountdir
-```shell
-yarn install --frozen-lockfile
 ```
 
-If you get an error regarding installation of the diskUsage module,
+# Author & License
-please install g++.
 
-If you get an error regarding level-down bindings, try clearing your yarn cache:
+- [Zenko CloudServer](https://s3-server.readthedocs.io/en/latest/) author is Scality, licensed under [Apache License, version 2.0](https://www.apache.org/licenses/LICENSE-2.0)

-
-## 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.
