[Stellaris] Our civilization is doomed. How can we leave a message for the future?

Our people, the Akar, began at the bottom of the seas of our homeworld thousands of years ago. We raced towards the future, elevated past factionalism, and took to the stars.
In the process of finding new worlds, we found a paradise beyond scientific understanding in a world called Divinity.

It was a "Holy World" of an empire that was spacefaring when our species was still  fumbling with bronze and glass. We have been defeated in every single stage of our conflict despite all of our best efforts. Even as I write this, the core worlds of my people burn.

We have perhaps days before the fleet of our enemy comes within an AU distance and glasses our homeworld to set an example. We want to leave a message to anyone who may find our world in the distant future, one sharing our collective sorrow and hopes we once knew. 

How can we, as an enemy plans to boil our seas and char our surface? To poison our atmosphere and unleash bio-engineered nightmares upon our children? What can be done?

Begin mass producing faster than light capable probes with as much data on your race and culture as is possible and start shooting them off in every direction imaginable. Many will be destroyed. Many more will drift for centuries, millennia, to be occasionally found and translated. Someone, somewhere, will remember you.
