title: Why GitHub suggest "prefix your version names with the letter v?"
body: <p>This is the content at GitHub's right sidebar: </p>
  
  <blockquote>
    <p>Tagging suggestions It’s common practice to prefix your version names
    with the letter v. Some good tag names might be v1.0 or v2.3.4.</p>
    
    <p>If the tag isn’t meant for production use, add a pre-release version
    after the version name. Some good pre-release versions might be
    v0.2-alpha or v5.9-beta.3.</p>
    
    <p>Semantic versioning If you’re new to releasing software, we highly
    recommend reading about <a href="http://semver.org/" rel="noreferrer">semantic versioning</a>.</p>

  <p>I don't understand why <strong>prefix your version names with the letter v</strong>? Please explain for me, why prefix version names with letter <strong>v</strong> is best-practice?</p>
