+# N3 Testnet Storage node configuration
+
+There is a prepared configuration for NeoFS Storage Node deployment in
+N3 Testnet. The easiest way to deploy a Storage Node is to use the prepared
+docker image and run it with docker-compose.
+
+## Build image
+
+Prepared **frostfs-storage-testnet** image is available at Docker Hub.
+However, if you need to rebuild it for some reason, run
+`make image-storage-testnet` command.
+
+```
+$ make image-storage-testnet
+...
+Successfully built ab0557117b02
+Successfully tagged nspccdev/neofs-storage-testnet:0.25.1
+```
+
+## Deploy node
+
+To run a storage node in N3 Testnet environment, you should deposit GAS assets,
+update docker-compose file and start the node.
+
+### Deposit
+
+The Storage Node owner should deposit GAS to NeoFS smart contract. It generates a
+bit of sidechain GAS in the node's wallet. Sidechain GAS is used to send bootstrap tx.
+
+First, obtain GAS in N3 Testnet chain. You can do that with
+[faucet](https://neowish.ngd.network) service.
+
+Then, make a deposit by transferring GAS to NeoFS contract in N3 Testnet.
+You can provide scripthash in the `data` argument of transfer tx to make a
+deposit to a specified account. Otherwise, deposit is made to the tx sender.
+
+NeoFS contract scripthash in N3 Testnet is `b65d8243ac63983206d17e5221af0653a7266fa1`,
+so the address is `NadZ8YfvkddivcFFkztZgfwxZyKf1acpRF`.
+
+See a deposit example with `neo-go`.
+
+```
+neo-go wallet nep17 transfer -w wallet.json -r https://rpc01.testnet.n3.nspcc.ru:21331 \
+--from NXxRAFPqPstaPByndKMHuC8iGcaHgtRY3m \
+--to NadZ8YfvkddivcFFkztZgfwxZyKf1acpRF \
+--token GAS \
+--amount 1
+```
+
+### Configure
+
+Next, configure `node_config.env` file. Change endpoints values. Both
+should contain your **public** IP.
+
+```
+NEOFS_GRPC_0_ENDPOINT=65.52.183.157:36512
+NEOFS_NODE_ADDRESSES=65.52.183.157:36512
+```
+
+Set up your [UN/LOCODE](https://unece.org/trade/cefact/unlocode-code-list-country-and-territory)
+attribute.
+
+```
+NEOFS_GRPC_0_ENDPOINT=65.52.183.157:36512
+NEOFS_NODE_ADDRESSES=65.52.183.157:36512
+NEOFS_NODE_ATTRIBUTE_2=UN-LOCODE:RU LED
+```
+
+You can validate UN/LOCODE attribute in
+[NeoFS LOCODE database](https://git.frostfs.info/TrueCloudLab/frostfs-locode-db/releases/tag/v0.4.0)
+with frostfs-cli.
+
+```
+$ frostfs-cli util locode info --db ./locode_db --locode 'RU LED'

+Location: Saint Petersburg (ex Leningrad)
+Continent: Europe

+
+It is recommended to pass the node's key as a file. To do so, convert your wallet
+WIF to 32-byte hex (via `frostfs-cli` for example) and save it to a file.
+
+```
+// Print WIF in a 32-byte hex format
+$ frostfs-cli util keyer Kwp4Q933QujZLUCcn39tzY94itNQJS4EjTp28oAMzuxMwabm3p1s
+PrivateKey      11ab917cd99170cb8d0d48e78fca317564e6b3aaff7f7058952d6175cdca0f56
+PublicKey       02be8b2e837cab232168f5c3303f1b985818b7583682fb49026b8d2f43df7c1059
+WIF             Kwp4Q933QujZLUCcn39tzY94itNQJS4EjTp28oAMzuxMwabm3p1s
+Wallet3.0       Nfzmk7FAZmEHDhLePdgysQL2FgkJbaEMpQ

+
+// Save 32-byte hex into a file
+$ echo '11ab917cd99170cb8d0d48e78fca317564e6b3aaff7f7058952d6175cdca0f56' | xxd -r -p > my_wallet.key
+```
+
+Then, specify the path to this file in `docker-compose.yml`
+```yaml
+     volumes:
+      - frostfs_storage:/storage
+      - ./my_wallet.key:/node.key
+```
+
+
+NeoFS objects will be stored on your machine. By default, docker-compose
+is configured to store objects in named docker volume `frostfs_storage`. You can
+specify a directory on the filesystem to store objects there.
+
+```yaml
+     volumes:
+       - /home/username/frostfs/rc3/storage:/storage
+       - ./my_wallet.key:/node.key
+```
+
+### Start
+
+Run the node with `docker-compose up` command and stop it with `docker-compose down`.
+
+### Debug
+
+To print node logs, use `docker logs frostfs-testnet`. To print debug messages in
+log, set up log level to debug with this env:
+
+```yaml
+     environment:
+       - NEOFS_LOGGER_LEVEL=debug
+```
