+
+Ozone provides S3 compatible REST interface to use the object store data with any S3 compatible
tools.
+
+## Getting started
+
+S3 Gateway is a separated component which provides the S3 compatible. It should be started
additional to the regular Ozone components.
+
+You can start a docker based cluster, including the S3 gateway from the release package.
+
+Go to the `compose/ozones3` directory, and start the server:
+
+```bash
+docker-compose up -d
+```
+
+You can access the S3 gateway at `http://localhost:9878`
+
+## URL Schema
+
+Ozone S3 gateway supports both the virtual-host-style URL s3 bucket addresses (eg. http://bucketname.host:9878)
and the path-style addresses (eg. http://host:9878/bucketname)
+
+By default it uses the path-style addressing. To use virtual host style URLs set your main
domain name in your `ozone-site.xml`:
+
+```xml
+<property>
+   <name>ozone.s3g.domain.name</name>
+   <value>s3g.internal</value>
+</property>
+```
+
+## Bucket browser
+
+Bucket's could be browsed from the browser with adding `?browser=true` to the bucket URL.
+
+For example the content of the 'testbucket' could be checked from the browser using the URL
http://localhost:9878/testbucket?browser=true
+
+
+## Implemented REST endpoints
+
+Operations on S3Gateway service:
+
+Endpoint    | Status      |
+------------|-------------|
+GET service | implemented |
+
+Operations on Bucket:
+
+Endpoint                            | Status      | Notes
+------------------------------------|-------------|---------------
+GET Bucket (List Objects) Version 2 | implemented |
+HEAD Bucket                         | implemented |
+DELETE Bucket                       | implemented |
+PUT Bucket (Create bucket)          | implemented |
+Delete Multiple Objects (POST)      | implemented |
+
+Operation on Objects:
+
+Endpoint                            | Status          | Notes
+------------------------------------|-----------------|---------------
+PUT Object                          | implemented     |
+GET Object                          | implemented     | Range headers are not supported
+Multipart Uplad                     | not implemented |
+DELETE Object                       | implemented     |
+HEAD Object                         | implemented     |
+
+
+## Security
+
+Security is not yet implemented, you can *use* any AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
+
+Note: Ozone has a notion for 'volumes' which is missing from the S3 Rest endpoint. Under
the hood S3 bucket names are maped to Ozone 'volume/bucket' locations (depending from the
given authentication information).
+
+To show the storage location of a S3 bucket, use the `ozone sh bucket path <bucketname>`
command.
+
+```
+aws s3api --endpoint-url http://localhost:9878 create-bucket --bucket=bucket1
+
+ozone sh bucket path bucket1
+Volume name for S3Bucket is : s3thisisakey
+Ozone FileSystem Uri is : o3fs://bucket1.s3thisisakey
+```
+
+## Clients
+
+### AWS Cli
+
+`aws` CLI could be used with specifying the custom REST endpoint.
+
+```
+aws s3api --endpoint http://localhost:9878 create-bucket --bucket buckettest
+```
+
+Or
+
+```
+aws s3 ls --endpoint http://localhost:9878 s3://buckettest
+```
+
+### S3 Fuse driver (goofys)
+
+Goofys is a S3 FUSE driver. It could be used to any mount any Ozone bucket as posix file
system:
+
+
+```
+goofys --endpoint http://localhost:9878 bucket1 /mount/bucket1
+```
