+## User registration
+
+To be able to interact with FrostFS Storage using s3-gw the user (whose credential is used) must be registered in
+`frostfsid` contract and also must have allowed chain rules in `policy` contract.
+
+### CLI parameters
+
+**Required parameters:**
+
+* `--wallet` is a path to a wallet `.json` file. You can provide a passphrase to decrypt
+  a wallet via environment variable `AUTHMATE_WALLET_PASSPHRASE`, or you will be asked to enter a passphrase
+  interactively. You can also specify an account address to use from a wallet using the `--address` parameter. Key from
+  this wallet will be registered in `frostfsid` contract and for this key allowed rules will be added.
+* `--rpc-endpoint` -- NEO node RPC address.
+
+**Optional parameters:**
+
+* `--frostfsid-contract` -- FrostfsID contract hash (LE) or name in NNS to register public key in contract (
+  default: `frostfsid.frostfs`).
+* `--username` -- Username to set for public key in frostfsid contract.
+* `--namespace` -- Namespace to register public key in frostfsid contract and add allowed rules (default: `""`).
+* `--contract-wallet` -- is a path to a contract wallet `.json` file. This wallet will be used to sign transactions
+  (if missing key from wallet flag be used). You can provide a passphrase to decrypt
+  a wallet via environment variable `AUTHMATE_WALLET_CONTRACT_PASSPHRASE`, or you will be asked to enter a passphrase
+  interactively. You can also specify an account address to use from a wallet using the `--contract-wallet-address`
+  parameter.
+* `--policy-contract` -- Policy contract hash (LE) or name in NNS to save allowed chains for key (
+  default: `policy.frostfs`).
+* `--proxy-contract` -- Proxy contract hash (LE) or name in NNS to use when interact with frostfsid contract (
+  default: `proxy.frostfs`).
+
+Example command that not only create access keys for key, but also register key in frostfsid contract and
+create allowed rules in policy contract:
+
+```shell
+$ frostfs-s3-authmate register-user --wallet subject-wallet.json \
+  --contract-wallet wallet-registered-in-proxy-contract.json \
+  --frostfsid-contract frostfsid.frostfs \
+  --namespace "" \
+  --usrername devenv \
+  --proxy-contract proxy.frostfs \
+  --policy-contract policy.frostfs \
+  --rpc-endpoint http://morph-chain.frostfs.devenv:30333
+
+Added policy rules:
+kind: 'u'
