Thank you Steve. I followed hello_word and created the page but I still do not know how to put the embed code. I tried putting it in star.php but it gave an error. Do you have any other ideas?
I would also like to have knowledge to update old and abandoned plugins
In my opinion the docs of Elgg contain sufficient information on how to update plugins to work on newer Elgg versions. But they are not meant as a basic course in learning to code. You need some basic knowledge in coding in php (Javascript, html, css, jquery is helpful, too) to be able to code an Elgg plugin in the first place. With the basic knowledge (there are many places to gain this knowledge on the Internet or just buy some books) you can learn about the Elgg API on the docs pages and tutorials of Elgg to be able to code an Elgg plugin and also how to update a plugin. Creating/updating an Elgg plugin is no magic. But you also can't expect that you can gain that knowledge in just a few minutes/days and then be an expert.
