+### NEP-11 token functions
+
+`wallet nep11` contains a set of commands to use for NEP-11 tokens. Token
+metadata related commands (`info`, `import` and `remove`) works the same way as
+for NEP-17 tokens. The syntax of other commands is very similar to NEP-17
+commands with the following adjustments.
+
+#### Balance
+
+Specify token ID via `--id` flag to call divisible NEP-11 `balanceOf` method:
+
+```
+./bin/neo-go wallet nep11 balance -w /etc/neo-go/wallet.json --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id R5OREI5BU+Uyd23/MuV/xzI3F+Q= -r http://localhost:20332
+```
+
+By default, no token ID specified, i.e. common `balanceOf` method is called.
+
+#### Transfers
+
+Specify token ID via `--id` flag to transfer NEP-11 token. Specify amount to
+transfer divisible NEP-11 token:
+
+```
+./bin/neo-go wallet nep11 transfer -w wallet.nep6 -r http://localhost:20332 --to NjEQfanGEXihz85eTnacQuhqhNnA6LxpLp --from NMe64G6j6nkPZby26JAgpaCNrn1Ee4wW6E --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id R5OREI5BU+Uyd23/MuV/xzI3F+Q= --amount 5
+```
+
+By default, no amount is specified, i.e. the whole token is transferred for
+non-divisible tokens and 100% of the token is transferred if there is only one
+owner of this token for divisible tokens.
+
+Unlike NEP-17 tokens functionality, `multitransfer` command currently not
+supported on NEP-11 tokens.
+
+#### Tokens Of
+
+To print token IDs owned by the specified owner, use `tokensOf` command with
+`--token` and `--address` flags:
+
+```
+./bin/neo-go wallet nep11 tokensOf -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731 --address NbrUYaZgyhSkNoRo9ugRyEMdUZxrhkNaWB
+```
+
+#### Owner Of
+
+For non-divisible NEP-11 tokens only. To print owner of non-divisible NEP11 token
+use `ownerOf` method, specify token hash via `--token` flag and token ID via
+`--id` flag:
+
+```
+./bin/neo-go wallet nep11 ownerOf -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id R5OREI5BU+Uyd23/MuV/xzI3F+Q=
+```
+
+#### Optional methods
+
+##### 1. Properties
+
+If NEP-11 token supports optional `properties` method, specify token hash via
+`--token` flag and token ID via `--id` flag to print properties:
+
+```
+./bin/neo-go wallet nep11 properties -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731 --id 7V5gjT2WwjP3pBCQMKGMfyZsp/w=
+```
+
+##### 2. Tokens
+
+If NEP-11 token supports optional `tokens` method, specify token hash via
+`--token` flag to print the list of token IDs minted by the specified NFT:
+
+```
+./bin/neo-go wallet nep11 tokens -r http://localhost:20332 --token 67ecb7766dba4acf7c877392207984d1b4d15731
