Before you choose

Requirements & limits

The repository is public and accessible on GitHub. The documented local build workflow requires mdBook installed through Cargo.

  • It provides specifications rather than a user-facing blockchain application.
  • The documentation is maintained as Markdown and built with mdBook.
  • The README documents mdbook build and mdbook serve for local book generation and browsing.
  • The repository is licensed under Apache-2.0.
  • Contribution formatting references GitHub Flavored Markdown, markdownlint and Markdown Table Prettifier.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Generate and browse a local mdBook from the repository's Markdown specifications.

Before you start

  • A local copy of the Fuel Specifications repository.
  • mdBook installed through Cargo.
  • A new terminal session after installing mdBook, as instructed by the README.

Steps

  1. Install mdBook with the command below.

    Documented command
    cargo install mdbook

  2. Open a new terminal session.

  3. Run mdbook build to build the book.

  4. Run mdbook serve to serve the book locally for browsing.

Expected outcome

A generated or locally served version of the Fuel Specifications book.

Guide limitations
