How to build a colonial ship in endless space

Click on the Galaxy interface and click on the "boat" icon in the lower left corner. There is an immigrant boat inside.

A colonial ship will be sent at the beginning of the game.

Only a planet with a population greater than or equal to 2 in the galaxy can build an immigrant ship, and building an immigrant ship will consume a population.

When the immigrant ships arrive in the reserved galaxy, and there are no hostile ships in the galaxy, the colonized planet can be colonized.

The more colonial ships a galaxy builds, the more discontent in the galaxy will expand.
