+This utility allows you to get the list of supported interfaces of your contract or find out if your contract supports a specific interface by id.
+
+This page describes how to use [PSP61](/) in your contract.
+
+## Step 1: Use implementation macro
+
+With [default `Cargo.toml`](../../overview.md/#the-default-toml-of-your-project-with-openbrush),
+you need to enable `psp61` feature, embed modules data structures and implement them via `#[openbrush::implementation]` macro
+as described in [this section](../../overview.md/#reuse-implementation-of-traits-from-openbrush).
+
+```rust
+#![cfg_attr(not(feature = "std"), no_std, no_main)]
+
+#[openbrush::implementation(..., PSP61, ...)]
+#[openbrush::contract]
+pub mod your_contract {
+    ...
+}
+```
+
+## Step 2: Use supported_interfases macro
+If your contract implements only openbrush interfaces, you can use `supported_interfaces` macro to implement `PSP61` interface like that:
+```rust
+supported_interfaces!(Contract);
+```
+But if your contract implements other interfaces with ids: ID1, ID2, ... , you need to implement `PSP61` interface manually:
+```rust
+supported_interfaces!(Contract, ID1, ID2, ...);
+```
+
+## Step 3: Example
+In this example we will implement `Ownable`, `AccessControl`, `Pausable`, `Upgradeable` interfaces in our contract and then implement `PSP61` interface. 
+```rust
+#![cfg_attr(not(feature = "std"), no_std, no_main)]
+
+#[openbrush::implementation(PSP61, Ownable, AccessControl, Pausable, Upgradeable)]
+#[openbrush::contract]
+pub mod my_psp61 {
+    use ink::prelude::{
+        vec,
+        vec::Vec,
+    };
+    use openbrush::{
+        contracts::supported_interfaces,
+        traits::{
+            Storage,
+            String,
+        },
+    };
+
+    #[ink(storage)]
+    #[derive(Default, Storage)]
+    pub struct Contract {
+        #[storage_field]
+        pub ownable: ownable::Data,
+        #[storage_field]
+        pub access_control: access_control::Data,
+        #[storage_field]
+        pub pausable: pausable::Data,
+    }
+
+    supported_interfaces!(Contract);
+
+    impl Contract {
+        #[ink(constructor)]
+        pub fn new() -> Self {
+            Self::default()
+        }
+
+        #[ink(message)]
+        pub fn ownable_id(&self) -> u32 {
+            ownable::ownable_external::TRAIT_ID
+        }
+
+        #[ink(message)]
+        pub fn access_control_id(&self) -> u32 {
+            access_control::accesscontrol_external::TRAIT_ID
+        }
+
+        #[ink(message)]
+        pub fn pausable_id(&self) -> u32 {
+            pausable::pausable_external::TRAIT_ID
+        }
+
+        #[ink(message)]
+        pub fn upgradeable_id(&self) -> u32 {
+            upgradeable::upgradeable_external::TRAIT_ID
+        }
+
+        #[ink(message)]
+        pub fn psp61_id(&self) -> u32 {
+            psp61::psp61_external::TRAIT_ID
+        }
+
+        #[ink(message)]
+        pub fn id_batch(&self) -> Vec<(String, u32)> {
+            vec![
+                (String::from("ownable"), ownable::ownable_external::TRAIT_ID),
+                (
+                    String::from("access_control"),
+                    access_control::accesscontrol_external::TRAIT_ID,
+                ),
+                (String::from("pausable"), pausable::pausable_external::TRAIT_ID),
+                (String::from("upgradeable"), upgradeable::upgradeable_external::TRAIT_ID),
+                (String::from("psp61"), psp61::psp61_external::TRAIT_ID),
+            ]
+        }
+    }
+}
+```
+
+That's it! Now you can use [PSP61](/) in your contract.
+
