Lie Groups and Lie Algebras, chapter III, § 3. Passage from a Lie group to its Lie algebra

Let AA be a finite-dimensional algebra. Suppose that KK is of characteristic 0. The automorphism group Aut(A)\mathrm{Aut}(A) of AA is a Lie subgroup of GL(A)\mathbf{GL}(A) and L(Aut(A))L(\mathrm{Aut}(A)) is the Lie algebra of derivation of AA.

This follows from Corollary 1 (applied to E=L(A,A;A)E = \mathscr{L}(A, A; A)) and Corollary 2 of Proposition 39 (applied to the subset of EE consisting only of multiplication on AA).

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
