Platform & Content License

Content Storage

The content in ION Wiki lives in GitHub:
Anyone can make a local copy! This is a significant advantage:
  • your contributions won't be lost if a Mediawiki database goes offline
  • straightforward porting between platforms that support Git-backed content storage
  • contribute through the GitBook UI or your interface of choice using GitHub pull requests

Choosing GitBook

After evaluating a dozen potential platforms for this wiki, we selected GitBook.
  • GitBook supports editing in Markdown.
  • GitBook supports Git-backed content storage.
  • GitBook has a modern design and mobile friendliness.
  • GitBook supports simple sign-in with GitHub or Google accounts.
  • GitBook has rapid and responsive support.
  • Because the Lightning Network is an open source software project, GitBook has allowed us to invite contributors to this wiki without paying the usual per-user fees.
  • GitBook is a hosted solution.
  • GitBook is not free and open source software.
  • GitBook does not have a plugin system—the features it ships with are the features you get.
  • GitBook is not as well-known, so contributors are less likely to be familiar with it.
  • GitBook has limited user and content management tools.
    • e.g. users can't edit in the GitBook UI without signing up.
    • e.g. edits by certain users can't require approval before going live.
    • e.g. pages can't be protected from editing.
In total, we believe that the advantages outweigh the disadvantages for this particular project. We will continue to evaluate other projects, like the upcoming wiki.js v2 beta, to see if they are a better fit.
