=== Creating the Mod File Structure ===
* Go to the location of the mod files that you generated in the steps above.
* On Windows, enter the My Documents folder.<ref name="MYDOCUMENTS" />
* In the My Documents folder, enter the Paradox Interactive folder. In Paradox Interactive, enter the Stellaris folder. In Stellaris, enter the Mod folder.
* Create a new folder in the mod folder named 'common'
* Create a new folder in the mod folder named 'gfx'
* In the main Stellaris window, open 'common' and copy the following folder to the Mod window:
: species_classes

There should be exactly one file in the folder you copied.
* Change that file’s name from 00_species_classes to anything you choose. '''DO NOT''' name it "00 or 01_species_classes" or any other numerical variant.
* Open the new file.
* Decide now whether the new species is going to be a mammal, reptile, avian, arthropod, mollusk, or fungus.
* Let’s say you've chosen to add a new fungus. Scroll down through the file until you find the section that reads:
<syntaxhighlight lang="ruby">
 FUN = {
 	portraits = {
 		"fun1"
 		"fun2"
 		"fun3"
 		"fun4"
 		"fun6"
 		"fun7"
 		"fun8"
 		"fun9"
 		"fun10"
 		"fun11"
 		"fun12"
 		"fun13"
 		"fun14"
 		"fun15"
 	}
 	custom_portraits = { # add additional portraits when customizing species
 		trigger = {	local_has_dlc = "Creatures of the Void Portrait Pack"	}
 		portraits = {
 			"fun16"
 		}
 	}

 	graphical_culture = fungoid_01
 	move_pop_sound_effect = "fungoid_pops_move"
 }
</syntaxhighlight>

* Now paste the following section in right ABOVE the line that says "graphical_culture = fungoid_01" and change myspecies1 to the name of the species:

<syntaxhighlight lang="ruby">
 	custom_portraits = {#add additional portraits when customizing species
 		trigger = {	always = yes	}
 		portraits = {
 			"myspecies1"
 		}
 	}
</syntaxhighlight>

{{ambox
| image = [[File:Ambox warning pn.png|40px|link=]]
| text = '''WARNING: DO NOT NAME YOUR PORTRAIT "MYSPECIES1" OR "MYSPECIES". This is the system default! An unique name must be used to prevent incompatibility with other Mods!
 }}

* Don't worry about what "trigger = {always = yes}" means, it just ensures that you don't need any special DLC or other requirements to use this portrait.

* Save and close the file.

Next step: In the mod folder navigate to the main directory and open the 'gfx' folder.
* Create a new folder named 'models' and open it.
* Create a new folder (inside of 'models') and name it 'portraits' {'gfx\models\portraits'} – this is where you will put the picture of the species.
* Inside of the 'gfx' folder create a new folder named 'portraits' then open that folder ('gfx\portraits') and create ANOTHER folder named 'portraits' ('gfx\portraits\portraits')
* Keep the folder 'gfx\models\portraits' open.
