I'm a little stuck... Click here to teach me more about this clue!

'charitable establishment' is the definition.
'soup kitchen' can be an answer for 'establishment' (soup kitchen is a kind of establishment). I'm not certain of the 'charitable' bit.

'cushion kept moving' is the wordplay.
'moving' indicates an anagram.
'cushion'+'kept'='cushionkept'
'cushionkept' anagrammed gives 'SOUP-KITCHEN'.

'in' is the link.

Can you help me to learn more?
