 #### Authentication
 
-Read more about request authentication in [docs/authentication.md](./docs/authemtnication.md)
+You can always upload files to public containers (open for anyone to put
+objects into), but for restricted containers you need to explicitly allow PUT
+operations for a request signed with your HTTP Gateway keys.
+
+If your don't want to manage gateway's secret keys and adjust eACL rules when
+gateway configuration changes (new gate, key rotation, etc) or you plan to use
+public services, there is an option to let your application backend (or you) to
+issue Bearer Tokens ans pass them from the client via gate down to NeoFS level
+to grant access.
+
+NeoFS Bearer Token basically is a container owner-signed ACL data (refer to NeoFS
+documentation for more details). There are two options to pass them to gateway:
+ * "Authorization" header with "Bearer" type and base64-encoded token in
+   credentials field
+ * "Bearer" cookie with base64-encoded token contents
+
+For example, you have a mobile application frontend with a backend part storing
+data in NeoFS. When a user authorizes in the mobile app, the backend issues a NeoFS
+Bearer token and provides it to the frontend. Then, the mobile app may generate
+some data and upload it via any available NeoFS HTTP Gateway by adding
+the corresponding header to the upload request. Accessing the ACL protected data
+works the same way.
+
+##### Example
+In order to generate a bearer token, you need to know the container owner key and 
+the address of the sender who will do the request to NeoFS (in our case, it's a gateway wallet address).
+
+Suppose we have:
+* **KxDgvEKzgSBPPfuVfw67oPQBSjidEiqTHURKSDL1R7yGaGYAeYnr** (container owner key)
+* **NhVtreTTCoqsMQV5Wp55fqnriiUCpEaKm3** (token owner address)
+* **BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K** (container id)
+
+Firstly, we need to encode the container id and the sender address to base64 (now it's base58). 
+So use **base58** and **base64** utils.
+
+1. Encoding container id:
+```
+$ echo 'BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K' | base58 --decode | base64
+# output: mRnZWzewzxjzIPa7Fqlfqdl3TM1KpJ0YnsXsEhafJJg=
+```
+
+2. Encoding token owner id:
+```
+$ echo 'NhVtreTTCoqsMQV5Wp55fqnriiUCpEaKm3' | base58 --decode | base64
+# output: NezFK4ujidF+X7bB88uzREQzRQeAvdj3Gg==
+```
+
+Now, we can form a Bearer token (10000 is liftetime expiration in epoch) and save it to **bearer.json**:
+```
+{
+    "body": {
+        "eaclTable": {
+            "version": {
+                "major": 0,
+                "minor": 0
+            },
+            "containerID": {
+                "value": "mRnZWzewzxjzIPa7Fqlfqdl3TM1KpJ0YnsXsEhafJJg="
+            },
+            "records": []
+        },
+        "ownerID": {
+            "value": "NezFK4ujidF+X7bB88uzREQzRQeAvdj3Gg=="
+        },
+        "lifetime": {
+            "exp": "10000",
+            "nbf": "0",
+            "iat": "0"
+        }
+    },
+    "signature": null
+}
+```
+
+Next, sign it with the container owner key:
+```
+$ neofs-cli util sign bearer-token --from bearer.json --to signed.json -w ./wallet.json
+```
+Encoding to base64 to use via the header:
+```
+$ base64 -w 0 signed.json 
+# output: Ck4KKgoECAIQBhIiCiCZGdlbN7DPGPMg9rsWqV+p2XdMzUqknRiexewSFp8kmBIbChk17MUri6OJ0X5ftsHzy7NERDNFB4C92PcaGgMIkE4SZgohAxpsb7vfAso1F0X6hrm6WpRS14WsT3/Ct1SMoqRsT89KEkEEGxKi8GjKSf52YqhppgaOTQHbUsL3jn7SHLqS3ndAQ7NtAATnmRHleZw2V2xRRSRBQdjDC05KK83LhdSax72Fsw==
+```
+
+After that, the Bearer token can be used:
+
+```
+$ curl -F 'file=@cat.jpeg;filename=cat.jpeg' -H "Authorization: Bearer Ck4KKgoECAIQBhIiCiCZGdlbN7DPGPMg9rsWqV+p2XdMzUqknRiexewSFp8kmBIbChk17MUri6OJ0X5ftsHzy7NERDNFB4C92PcaGgMIkE4SZgohAxpsb7vfAso1F0X6hrm6WpRS14WsT3/Ct1SMoqRsT89KEkEEGxKi8GjKSf52YqhppgaOTQHbUsL3jn7SHLqS3ndAQ7NtAATnmRHleZw2V2xRRSRBQdjDC05KK83LhdSax72Fsw==" \
+  http://localhost:8082/upload/BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K
+# output:
+# {
+#	"object_id": "DhfES9nVrFksxGDD2jQLunGADfrXExxNwqXbDafyBn9X",
+#	"container_id": "BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K"
+# }
+```
+
+##### Note
+For the token to work correctly, you need to create a container with a basic ACL that:
+1. Allow PUT operation to others
+2. Doesn't set "final" bit
+
+For example:
+```
+$ neofs-cli -w ./wallet.json --basic-acl 0x0FFFCFFF -r 192.168.130.72:8080 container create --policy "REP 3"  --await
+```
+
+To deny access to a container without a token, set the eACL rules:
+```
+$ neofs-cli -w ./wallet.json -r 192.168.130.72:8080 container set-eacl --table eacl.json --await --cid BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K
+```
+
+File **eacl.json**:
+```
+{
+    "version": {
+        "major": 0,
+        "minor": 0
+    },
+    "containerID": {
+        "value": "mRnZWzewzxjzIPa7Fqlfqdl3TM1KpJ0YnsXsEhafJJg="
+    },
+    "records": [
+        {
+            "operation": "PUT",
+            "action": "DENY",
+            "filters": [],
+            "targets": [
+                {
+                    "role": "OTHERS",
+                    "keys": []
+                }
+            ]
+        }
+    ]
+}

-| `/zip/{cid}/{prefix}`, `/tar/{cid}/{prefix}`    | [Download objects in archive](#download-archive) |
-
-**Note:** `cid` parameter can be base58 encoded container ID or container name
-(the name must be registered in NNS, see appropriate section in [nns.md](./nns.md)).
-
-Route parameters can be:
-
-* `Single` - match a single path segment (cannot contain `/` and be empty)
-* `Catch-All` - match everything (such parameter usually the last one in routes)
-* `Query` - regular query parameter
-
-### Bearer token
-
-All routes can accept [bearer token](./authentication.md) from:
-
-* `Authorization` header with `Bearer` type and base64-encoded token in
-  credentials field
-* `Bearer` cookie with base64-encoded token contents
-
-Example:
-
-Header:
-
-```
-Authorization: Bearer ChA5Gev0d8JI26tAtWyyQA3WEhsKGTVxfQ56a0uQeFmOO63mqykBS1HNpw1rxSgaBgiyEBjODyIhAyxcn89Bj5fwCfXlj5HjSYjonHSErZoXiSqeyh0ZQSb2MgQIARAB

-| `X-Attribute-*`        | Used to set regular object attributes <br/> (e.g. use "X-Attribute-My-Tag" to set `My-Tag` attribute).                                                                                                                                                                                                                      |
-| `X-Explode-Archive`    | If set, gate tries to read files from uploading `tar` archive and creates an object for each file in it. Uploading `tar` could be compressed via Gzip by setting a `Content-Encoding` header. Sets a `FilePath` attribute as a relative path from archive root and a `FileName` as the last path element of the `FilePath`. |
-| `Content-Encoding`     | If set and value is `gzip`, gate will handle uploading file as a `Gzip` compressed `tar` file.                                                                                                                                                                                                                              |
-| `Date`                 | This header is used to calculate the right `__SYSTEM__EXPIRATION` attribute for object. If the header is missing, the current server time is used.                                                                                                                                                                          |

-There are some reserved headers type of `X-Attribute-FROSTFS-*` (headers are arranged in descending order of priority):
-
-1. `X-Attribute-System-Expiration-Epoch: 100`
-2. `X-Attribute-System-Expiration-Duration: 24h30m`
-3. `X-Attribute-System-Expiration-Timestamp: 1637574797`
-4. `X-Attribute-System-Expiration-RFC3339: 2021-11-22T09:55:49Z`
-
-which transforms to `X-Attribute-System-Expiration-Epoch`. So you can provide expiration any convenient way.
-
-If you don't specify the `X-Attribute-Timestamp` header the `Timestamp` attribute can be set anyway
-(see http-gw [configuration](gate-configuration.md#upload-header-section)).
-
-The `X-Attribute-*` headers must be unique. If you provide several the same headers only one will be used.
-Attribute key and value must be valid utf8 string. All attributes in sum must not be greater than 3mb.
-
-###### Body
-
-Body must contain multipart form with file.
-The `filename` field from the multipart form will be set as `FileName` attribute of object
-(can be overriden by  `X-Attribute-FileName` header).

-# Request authentication
-
-HTTP Gateway does not authorize requests. Gateway converts HTTP request to a 
-FrostFS request and signs it with its own private key. 
-
-You can always upload files to public containers (open for anyone to put
-objects into), but for restricted containers you need to explicitly allow PUT
-operations for a request signed with your HTTP Gateway keys.
-
-If you don't want to manage gateway's secret keys and adjust policies when
-gateway configuration changes (new gate, key rotation, etc) or you plan to use
-public services, there is an option to let your application backend (or you) to
-issue Bearer Tokens and pass them from the client via gate down to FrostFS level
-to grant access.
-
-FrostFS Bearer Token basically is a container owner-signed policy (refer to FrostFS
-documentation for more details). There are two options to pass them to gateway:
-* "Authorization" header with "Bearer" type and base64-encoded token in
-  credentials field
-* "Bearer" cookie with base64-encoded token contents
-
-For example, you have a mobile application frontend with a backend part storing
-data in FrostFS. When a user authorizes in the mobile app, the backend issues a FrostFS
-Bearer token and provides it to the frontend. Then, the mobile app may generate
-some data and upload it via any available FrostFS HTTP Gateway by adding
-the corresponding header to the upload request. Accessing policy protected data
-works the same way.
-
-##### Example
-In order to generate a bearer token, you need to have wallet (which will be used to sign the token)
-
-1. Suppose you have a container with private policy for wallet key
-
-```
-$ frostfs-cli container create -r <endpoint> --wallet <wallet> -policy <policy> --basic-acl 0 --await
-CID: 9dfzyvq82JnFqp5svxcREf2iy6XNuifYcJPusEDnGK9Z
-
-$ frostfs-cli ape-manager add -r <endpoint> --wallet <wallet> \
-  --target-type container --target-name 9dfzyvq82JnFqp5svxcREf2iy6XNuifYcJPusEDnGK9Z \
-  --rule "allow Object.* RequestCondition:"\$Actor:publicKey"=03b09baabff3f6107c7e9acb8721a6fc5618d45b50247a314d82e548702cce8cd5 *" \
-  --chain-id <chainID>
-```
-
-
-2. Form a Bearer token (10000 is lifetime expiration in epoch) to impersonate
-   HTTP Gateway request as wallet signed request and save it to **bearer.json**:
-```
-{
-    "body": {
-        "allowImpersonate": true,
-        "lifetime": {
-            "exp": "10000",
-            "nbf": "0",
-            "iat": "0"
-        }
-    },
-    "signature": null
-}
-```
-
-3. Sign it with the wallet:
-```
-$ frostfs-cli util sign bearer-token --from bearer.json --to signed.json -w <wallet>
-```
-
-4. Encode to base64 to use in header:
-```
-$ base64 -w 0 signed.json
-# output: Ck4KKgoECAIQBhIiCiCZGdlbN7DPGPMg9rsWqV+p2XdMzUqknRiexewSFp8kmBIbChk17MUri6OJ0X5ftsHzy7NERDNFB4C92PcaGgMIkE4SZgohAxpsb7vfAso1F0X6hrm6WpRS14WsT3/Ct1SMoqRsT89KEkEEGxKi8GjKSf52YqhppgaOTQHbUsL3jn7SHLqS3ndAQ7NtAATnmRHleZw2V2xRRSRBQdjDC05KK83LhdSax72Fsw==
-```
-
-After that, the Bearer token can be used:
-
-```
-$ curl -F 'file=@cat.jpeg;filename=cat.jpeg' -H "Authorization: Bearer Ck4KKgoECAIQBhIiCiCZGdlbN7DPGPMg9rsWqV+p2XdMzUqknRiexewSFp8kmBIbChk17MUri6OJ0X5ftsHzy7NERDNFB4C92PcaGgMIkE4SZgohAxpsb7vfAso1F0X6hrm6WpRS14WsT3/Ct1SMoqRsT89KEkEEGxKi8GjKSf52YqhppgaOTQHbUsL3jn7SHLqS3ndAQ7NtAATnmRHleZw2V2xRRSRBQdjDC05KK83LhdSax72Fsw==" \
-  http://localhost:8082/upload/BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K
-# output:
-# {
-#	"object_id": "DhfES9nVrFksxGDD2jQLunGADfrXExxNwqXbDafyBn9X",
-#	"container_id": "BJeErH9MWmf52VsR1mLWKkgF3pRm3FkubYxM7TZkBP4K"
-# }
-```
-
-##### Note: Bearer Token owner
-
-You can specify exact key who can use Bearer Token (gateway wallet address).
-To do this, encode wallet address in base64 format
-
-```
-$ echo 'NhVtreTTCoqsMQV5Wp55fqnriiUCpEaKm3' | base58 --decode | base64
-# output: NezFK4ujidF+X7bB88uzREQzRQeAvdj3Gg==
-```
-
-Then specify this value in Bearer Token Json
-```
-{
-    "body": {
-        "ownerID": {
-            "value": "NezFK4ujidF+X7bB88uzREQzRQeAvdj3Gg=="
-        },
-        ...
-```
-
-##### Note: Policy override
-
-Instead of impersonation, you can define the set of policies that will be applied
-to the request sender. This allows to restrict access to specific operation and
-specific objects without giving full impersonation control to the token user.

-# Nicename Resolving with NNS
-
-Steps to start using name resolving:
-
-1. Enable NNS resolving in config (`rpc_endpoint` must be a valid neo rpc node, see [configs](./config) for other examples):
-
-```yaml
-rpc_endpoint: http://morph-chain.frostfs.devenv:30333
-resolve_order:
-  - nns
-```
-
-2. Make sure your container is registered in NNS contract. If you use [frostfs-dev-env](https://git.frostfs.info/TrueCloudLab/frostfs-dev-env)
-   you can check if your container (e.g. with `container-name` name) is registered in NNS:
-
-```shell
-$ curl -s --data '{"id":1,"jsonrpc":"2.0","method":"getcontractstate","params":[1]}' \
-    http://morph-chain.frostfs.devenv:30333 | jq -r '.result.hash'
-
-0x8e6c3cd4b976b28e84a3788f6ea9e2676c15d667
-
-$ docker exec -it morph_chain neo-go \
-    contract testinvokefunction \
-    -r http://morph-chain.frostfs.devenv:30333 0x8e6c3cd4b976b28e84a3788f6ea9e2676c15d667 \
-    resolve string:container-name.container int:16 \
-    | jq -r '.stack[0].value | if type=="array" then .[0].value else . end' \
-    | base64 -d && echo
-
-7f3vvkw4iTiS5ZZbu5BQXEmJtETWbi3uUjLNaSs29xrL
-```
-
-3. Use container name instead of its `$CID`. For example:
-
-```shell
-$ curl http://localhost:8082/get_by_attribute/container-name/FileName/object-name
-```
