<strong>Markdown acceptable here!</strong>This is your opportunity to clearly explain what
your resource is all about! It’s worth remembering that you are using the space to
communicate to two different audiences. Firstly, think about what fellow teachers
would like to know, such as exactly what the resource contains and how it could be used in
the classroom. Secondly, the words you include on this page are also talking to internal and
external search engines. External search engines, like Google, show the first 155 characters
of the resource description, so make sure you take advantage
of these characters by using lots of relevant keywords as part of an enticing pitch.
