Overview

Hello, Rollkit team! We are the buidlers from Artela. Recently we have integrated our EVM++ execution layer with Rollkit (👉 repo is here). Also that we have prepared a tutorial doc (in this PR) explaining how to setup an Artela rollup node with local DA and how to deploy smart contracts & Aspect (EVM++'s WASM extension) to the L2.

Summary by CodeRabbit

  • New Features

    • Introduced a new section titled "Artela EVM++" in the sidebar for improved navigation.
    • Added a comprehensive quick start guide for setting up an Artela EVM++ rollup node, including detailed instructions and community examples.
  • Documentation

    • Enhanced documentation for Artela EVM++, focusing on setup, operation, and practical applications.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

My general impression is, that in this tutorial you're setting up rollkit based development environment and then use public testnet. I understand that docs on Artela website are generic, but this tutorial could include some steps on how to configure deploy.mjs file to actually use local dev env and rollkit.

3-5: Clarify the usage of imported constants.

The script tag imports constants from a JavaScript file, but there is no visible usage of these constants in the provided snippet. Can you clarify if these constants are used later in the tutorial? If not, consider removing the import to clean up the code.


22-47: Verify Docker commands and expected outputs.

The Docker setup instructions are clear, but it's crucial to ensure that the commands and the expected outputs are accurate. Can you confirm if the provided Docker commands and the logs shown as expected outputs have been tested and are correct?


138-140: Well-Written Conclusion.

The conclusion effectively summarizes the tutorial's achievements and provides a positive closure. Well done!

74-93: Improve URL Presentation in Tutorial Instructions.

The instructions include a bare URL which could be improved for better readability and adherence to Markdown best practices. Consider embedding the URL within descriptive text or using Markdown link syntax to enhance the presentation and user experience.

Apply this diff to improve the URL presentation:

-1. Use https://github.com/artela-network/gm-portal.git instead of the original `gm-portal` repo.
+1. Use [artela-network/gm-portal](https://github.com/artela-network/gm-portal.git) instead of the original `gm-portal` repo.

1-12: Introduction looks good!

The introduction provides a clear overview of EVM++ and its capabilities. No changes are required.


13-20: Repository cloning instructions are accurate.

The instructions to clone the Artela Rollkit repository are clear and accurate. No changes are required.


22-47: Docker Compose instructions are accurate.

The instructions to run the Artela rollup node using Docker Compose are clear and accurate. No changes are required.


49-69: Security Concern: Display of Private Keys.

It's generally not a good practice to display private keys directly in documentation, even for testing purposes. Consider using placeholders like {YOUR_PRIVATE_KEY_HERE} and providing instructions on how users can generate their own keys. This approach enhances security practices and prevents accidental misuse.


102-110: "More to know" section looks good!

The links to essential concepts are helpful for users to gain a deeper understanding of Aspect. The LanguageTool hint suggesting an alternative to "deeper" can be safely ignored as "deeper" is an appropriate adjective in this context.
