How do I add a plugin to my Squarespace site?
You add a Squarewebsites plugin by pasting its code snippet into your site, then configuring it to your content. On Business plans and above, you paste the snippet into Code Injection for sitewide effect. On a Personal plan, you can often use a Code Block instead. After purchase you receive the code file and an installation guide.
Step 1: Check your plan’s method
Your Squarespace plan determines how you install. On Business plans and above, Squarespace enables Code Injection for sitewide Header and Footer placement. On a Personal plan you can often use a Code Block instead (Squarewebsites).
Step 2: Paste and configure
After purchase you receive a code file (typically a .txt file) plus a URL and password to an installation guide. Follow the guide’s “Simple Way” section: paste the code into Code Injection (or a Markdown block on Personal plans as a workaround), refresh your site, and then configure the options to match your content (Squarewebsites). For Universal Filter specifically, the “Get Filter Config” button generates the setup code for non-coders (Squarewebsites).
Step 3: Get help if needed
Every plugin includes free basic-setup support to get the standard configuration working (Squarewebsites). If you run into trouble, reach out via email or the Slack support forum (Squarewebsites).
