+# Massa Standard Definition
 
-This repository lists all massa standard specifications and reference implementations.
+Welcome to the Massa Standard Definition project!
 
-Massa standards
+This project aims to establish a common set of standards for the Massa blockchain ecosystem. The standards defined here will help to promote interoperability and ease of use for Massa-based applications and services.
 
-- [smart contracts](smart-contracts/README.md)
+If you're interested in learning more about Massa and its capabilities, check out the following resources:
 
-## How to write a standard?
+- [Massa website](https://massa.net): This is the official website for the Massa blockchain. Here, you can learn more about Massa's features and use cases, as well as explore the Massa ecosystem and community.
+- [Massa documentation](https://docs.massa.net/en/latest/): This is the official documentation for Massa. Here, you can find detailed guides and tutorials for developing on the Massa blockchain, as well as API reference documentation for the Massa SDK and other tools.
 
-Create a `.md` file that follow this structure:
+## Fungible Token
 
-```markdown
-# Standard name
+The [Fungible Token standard implementation](smart-contracts/assembly/contracts/FT) defines a common set of rules for creating and managing Massa-based tokens that are fungible (i.e. interchangeable).
 
-Initial issue: <https://github.com/massalabs/massa-standards/issues/{issue number}>
+This is MassaLabs implementation of [the ERC20](https://ethereum.org/en/developers/docs/standards/tokens/erc-20/).
 
-## Abstract
+## Non-Fungible Token
 
-## Motivation
+The [Non-Fungible Token standard implementation](smart-contracts/assembly/contracts/NFT) defines a common set of rules for creating and managing Massa-based tokens that are non-fungible (i.e. unique).
 
-## Specification
+This is MassaLabs implementation of [the ERC721](https://ethereum.org/en/developers/docs/standards/tokens/erc-721/).
 
-## Implementation
+## Massa Units
 
-```
+The [Massa Units standard](units.md) defines a set of common units of measurement for use on the Massa blockchain.
 
-Fill the issue number. The issue would probably be a meta issue. Sub-issues would be issue to implement
-the standard in proper repositories.
+These units include:
 
-> _NOTE:_ this [VSCode extension](https://marketplace.visualstudio.com/items?itemName=DavidAnson.vscode-markdownlint)
-can help you to format markdown files.
+- Massa coin
+- Gas
+- Rolls
+
+## DApps <> Wallet Provider Communication
+
+The [DApps <> Wallet Provider Communication standard](wallet/dapps-communication.md) defines a common interface for communication between Massa-based decentralized applications (DApps) and wallet providers.
+
+This standard aims to simplify the process of integrating Massa-based DApps with various wallet providers, making it easier for end-users to access and use these applications.
