+| ------------- | ------------- | ------------- |------------- |
+| 0a. | License |MIT| The MIT license is used in the project. |
+| 0b.  | Documentation |[Macros](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/proc_macros/lib.rs), [Examples and more general documentation](https://supercolony-net.github.io/openbrush-contracts/index.html)| All contracts have comments. The old documentation has been updated with new features introduced during this milestone. New features implemented via macro and contain the description in comments. | 
+| 0c.  | Testing Guide |[Macros](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/proc_macros/lib.rs), [Examples](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/examples), [Integration tests](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/tests)| Macros have been tested via rust documentation. The old examples have been updated according to new features(integration test for them without changes). | 
+| 1.  | Remove boilerplate code |[`#[brush::contract]`](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/proc_macros/lib.rs#L15), [`#[brush::trait_definition]`](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/proc_macros/lib.rs#L173)| Combination of `#[brush::contract]` and `#[brush::trait_definition]` macros allow to avoid boilerplate code. Example of `PSP22` contract [with this feature](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/examples/psp22/lib.rs#L20) and [without](https://github.com/Supercolony-net/openbrush-contracts/blob/20cd7a98f70f7a91d546baaa7cf032b6ba776e93/examples/erc20/lib.rs#L100). | 
+| 2.  | Derive for storages |[Derive macro rule](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush_derive_macro/lib.rs#L11), [Helper macro rules](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/macros.rs)| The library is using a clear and simple data model. If the user wants to reuse some trait from the library. He must derive corresponding storage(for [example](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/examples/psp22/lib.rs#L10)). If the user wants to define his trait, he has to define some data struct(for [example](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/contracts/token/psp22/traits.rs#L33)) and use `declare_storage_trait!` to declare a trait. The user also can easily create derive macro for his trait, by reusing `declare_derive_storage_trait!` macro rule(for [example](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/contracts/token/psp22/derive)). | 
+| 3.  | Support default implementation in external traits |[`#[brush::trait_definition]`](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/proc_macros/lib.rs#L173)| The macro allows having methods in the trait with default implementation of method, default types, constants, and any other stuff from the rust(except generics in ink! messages). [Example how it looks like](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/contracts/token/psp22/traits.rs#L70). | 
+| 4.  | Support of modifiers |[`#[brush::modifier_definition]`](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/proc_macros/lib.rs#L204), [`#[brush::modifiers]`](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/utils/brush/proc_macros/lib.rs#L336)| `#[brush::modifier_definition]` validates that modifier has been declared right according to expected rules. `#[brush::modifiers]` applies modifiers to a function. | 
+| 5.  | ReentrancyGuard |[Implementation](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/contracts/security/reentrancy-guard), [Example](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/examples/reentrancy-guard), [Integration test](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/tests/reentrancy_guard.tests.ts)| Implemented [ReentrancyGuard](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/security/ReentrancyGuard.sol) from OpenZeppelin. Added example and tests. | 
+| 6a.  | PaymentSplitter |[Implementation](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/contracts/finance/payment-splitter), [Example](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/examples/payment-splitter), [Integration test](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/tests/payment-splitter.tests.ts)| Implemented [PaymentSplitter](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/finance/PaymentSplitter.sol) from OpenZeppelin. Added example and tests. | 
+| 6b.  | TimelockController |[Implementation](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/contracts/governance/timelock-controller), [Example](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/examples/timelock-controller), [Integration test](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/tests/timelock-controller.tests.ts)| Implemented [TimelockController](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/governance/TimelockController.sol) from OpenZeppelin. Added example and tests. | 
+| 6c.  | Pausable |[Implementation](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/contracts/security/pausable), [Example](https://github.com/Supercolony-net/openbrush-contracts/tree/783406805c4ef86176d4a3500db6840c5b7f059a/examples/pausable), [Integration test](https://github.com/Supercolony-net/openbrush-contracts/blob/783406805c4ef86176d4a3500db6840c5b7f059a/tests/pausable.tests.ts)| Implemented [Pausable](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/security/Pausable.sol) from OpenZeppelin.
