Where can I find an elementary introduction (construction, description, main properties) to the Teichmüller space ${\cal T}_{1,n}$ of elliptic curves with $n$-marked points?

Same question for the following associated objects: mapping class group $\Gamma_{1,n}$ and moduli space ${\cal M}_{1,n}={\cal T}_{1,n}/\Gamma_{1,n}$.

Thanks in advance for any reference.
