README.md needs updating

[zkhan96]

bottom of the README should say:

            const data = document.querySelector(".institution_list").getAttribute("data-institutions");
            institutionSelector(JSON.parse(data), "institution-modal-content", config);

            const container = document.querySelector(".institution-container");
            const observer = new MutationObserver((event) => {
                const institutions = Array.from(document.querySelectorAll(".ob-list-institution > a"));
                console.log(institutions)
                institutions.forEach((institution) => {
                    institution.addEventListener("click", (e) => {
                        e.preventDefault();
                        const aspspId = e.currentTarget.getAttribute("data-institution");
                        window.location.href = `/agreements/${aspspId}`;
                    })
                })
            });

            const conf = {
                childList: true
            };
            observer.observe(container, conf);

Also please make a react template!
