How do you disclose your autistic identity to others?

Hello fellow autistic people.

I just wanted to see what other people’s experiences of disclosing were like. I have recently started telling people I am autistic and I don’t really know how to explain it because I either assume other people know what being autistic means (they don’t) or I think about explaining in too much depth for a particular situation. How do you explain your autistic needs and experience?

Thanks in advance.
