Start with nothing at home -- get equipment installed (6)
I believe the answer is:
origin
'start' is the definition.
(thesaurus)
'nothing at home get equipment installed' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'get' is a charade indicator (letters next to each other).
'equipment' becomes 'rig' (rig is a kind of equipment).
'installed' means one lot of letters goes inside another.
'o'+'in'='oin'
'oin' enclosing 'rig' is 'ORIGIN'.
'with' is the link.
(Other definitions for origin that I've seen before include "Where axes cut" , "Place or point of beginning (6)" , "Place where something begins" , "Where one begins" , "Beginning, starting point" .)
