Frequently asked questions
How do I avoid getting docs for the wrong library version?
Give the package name and exact version or ask Claude to read the lockfile first. Ask it to show the documentation link and say which version it found.
Why can’t I find Context7 after installing?
Check that your Claude client is supported and that you installed the plugin in the workspace or project you have open. In Claude Code, run /reload-plugins or reopen the session.
