 ## How to setup dev environment?
 
+**Note:** 
+This setup supports both Docker Compose V1 (using `docker-compose` commands) and Docker Compose V2 (using `docker compose` commands).
+Docker Compose V2 is preferable, as [from July 2023 Compose V1 stopped receiving updates](https://docs.docker.com/compose/).

 1. Install docker.
-1. Run `docker-compose build`.
-1. `cp .env.empty .env`.
-1. Start containers `docker-compose up -d`.
-1. Install project dependencies: `docker-compose exec workspace yarn`.
-1. To run tests: `docker-compose exec workspace truffle test`.
+1. Run `docker compose build`.

+1. To clean artifacts and cache: `docker compose exec workspace npx hardhat clean`.
+1. Stop containers `docker compose down`.

+## Contribution Guide
+
+- Run Docker tests to ensure that the project is set up successfully.
+- Write tests for new contracts and functionalities.
+- Run tests to confirm that new implementations work correctly.
+- Format Solidity code before opening a pull request (PR). For formatting, you can use Remix Online IDE - https://remix.ethereum.org/
+
+## Where Can I Write Solidity Code?
+
+### Notes for Those Without an IDE:
+Using Remix Online IDE is sufficient. There's no need to install anything locally.
+
+### Notes for JetBrains or Visual Studio Code (VSCode) Users:
+- These IDEs offer Solidity and HardHat plugins, which can simplify your workflow. However, Remix Online IDE is also a viable option.
+- To index JavaScript code, execute the Docker commands as mentioned. Necessary dependencies will be downloaded, enabling the IDE to index the rest of the code.
