+
+=======================
+S3 Object Storage Setup
+=======================
+
+Parsec is compatible with different object storage solutions, including:
+
+- `OpenStack Swift <https://docs.openstack.org/swift/latest/>`_
+- `Amazon S3 <https://aws.amazon.com/s3/>`_ or any S3-compatible storage such as `Outscale's OOS <https://docs.outscale.com/en/userguide/OUTSCALE-Object-Storage-OOS.html>`_ (most storage providers offer S3-compatible APIs)
+- A RAID configuration combining multiple storages
+
+The most common deployment approach is to use an S3-compatible storage.
+
+This guide provides instructions for setting up an S3-compatible bucket for use with Parsec.
+
+.. note::
+
+  Parsec has a very basic use of the object storage: it only reads existing objects and creates new objects.
+  There is no deletion or listing of objects. Therefore, enabling versioning for the bucket is not strictly
+  required, but it is **highly recommended** to prevent data loss from overwriting an existing object (since S3
+  uses eventual consistency, the ``s3:PutObject`` policy always allows overwriting an existing object).
+
+Prerequisites
+=============
+
+- An S3-compatible storage provider account
+- The `AWS CLI <https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html>`_
+- Appropriate permissions to create buckets and manage policies
+
+.. _doc_hosting_deployment_s3_create_bucket:
+
+Create the Bucket
+-----------------
+
+Create a new bucket for Parsec data storage:
+
+.. code-block:: console
+
+  aws s3api create-bucket \
+      --bucket <BUCKET_NAME>
+
+Replace ``<BUCKET_NAME>`` with your desired bucket name.
+
+.. note::
+
+  The exact command may vary depending on your storage provider. Consult your provider's documentation
+  for the appropriate command syntax.
+
+  For example, with Outscale:
+
+  .. code-block:: console
+
+    aws s3api create-bucket \
+        --profile <PROFILE_NAME> \
+        --endpoint https://oos.eu-west-2.outscale.com \
+        --bucket <BUCKET_NAME>
+
+.. _doc_hosting_deployment_s3_enable_versioning:
+
+Enable Versioning
+-----------------
+
+Enable versioning on the bucket to protect against accidental overwrites:
+
+.. code-block:: console
+
+  aws s3api put-bucket-versioning \
+      --bucket <BUCKET_NAME> \
+      --versioning-configuration Status=Enabled
+
+.. _doc_hosting_deployment_s3_limit_access:
+
+Limit Access with a Dedicated User
+----------------------------------
+
+For security reasons, create a dedicated IAM user with restricted permissions to only the necessary operations.
+
+The following bucket policy grants only the required permissions for Parsec to function:
+
+.. code-block:: console
+
+  aws s3api put-bucket-policy \
+      --bucket <BUCKET_NAME> \
+      --policy '{
+     "Version": "2012-10-17",
+     "Statement": [
+        {
+           "Effect": "Allow",
+           "Principal": {
+              "AWS": "arn:aws:iam::<ACCOUNT_ID>:root"
+           },
+           "Action": [
+              "s3:GetObject",
+              "s3:PutObject"
+           ],
+          "Resource": "arn:aws:s3:::<BUCKET_NAME>/*"
+        },
+        {
+           "Effect": "Allow",
+           "Principal": {
+              "AWS": "arn:aws:iam::<ACCOUNT_ID>:root"
+           },
+           "Action": [
+              "s3:ListBucket"
+           ],
+          "Resource": "arn:aws:s3:::<BUCKET_NAME>"
+        }
+     ]
+  }'
+
+Replace the following placeholders:
+
+- ``<BUCKET_NAME>``: Your bucket name
+- ``<ACCOUNT_ID>``: The AWS account ID or IAM user that needs access
