linter-node-markdownlint is a plugin for the Atom text editor that checks your Markdown files for formatting issues as you write them. If you've ever had a README or documentation file look slightly off, inconsistent headers, weird spacing, or broken lists, this tool catches those problems the moment they happen, right in your editor. Under the hood, it wraps an existing tool called markdownlint, which has a large set of rules for what "good" Markdown should look like. The plugin brings those rules into Atom so you see warnings and errors inline, without needing to run a separate command or switch to a terminal. You can control which rules matter to you by placing a configuration file called .markdownlintrc in your project folder. That file can be written in either JSON or INI format, and it lets you turn rules on or off, or tweak specific settings like how much indentation you prefer. The README includes examples of both formats so you can see exactly how to structure the file. This is useful for anyone who writes documentation regularly, developers maintaining project READMEs, technical writers working on docs sites, or teams who want their Markdown files to follow a consistent style across many contributors. For example, if your team has decided that all headers should use a specific format and lists should always be indented four spaces, you can encode those preferences once and the plugin will enforce them automatically for everyone using it. The project is written in CoffeeScript, which was a popular choice for Atom plugins, though that detail won't matter much to anyone just using the tool. Note that Atom itself was discontinued by GitHub in 2022, so this plugin is primarily relevant if you're still working in an existing Atom setup rather than starting fresh.
