 Here is how to do it : 
 
+## Pre-requisites: 
+
+* A development environment for DCS Liberation, see https://github.com/Khopa/dcs_liberation/wiki/Developer's-Guide
+* Basic Python programming knowledge
+* A DCS World open beta installation
+
 ## Step 1 : Pydcs extensions injection : 
 
 Adding support for a modded aircraft is much more complicated than adding its name in a faction file.

 ## Step 2 : Pydcs extensions injection : 
 
-Once you've created your extension, you need to inject it's content into the pydcs version run by Liberation. This is done at runtime.
+Once you've created your extension, you need to inject it's content into the pydcs version run by Liberation. This is done at runtime in db.py.
 
-[WIP]
+If your modded content is a plane, you need to inject it to pydcs plane_map, in the file [db.py](https://github.com/Khopa/dcs_liberation/blob/develop/game/db.py)
+
+
+```python
+plane_map["A-4E-C"] = A_4E_C
+plane_map["F-22A"] = F_22A
+plane_map["MB-339PAN"] = MB_339PAN
+[...]
+```
+
+If this is a vehicle, add it to vehicle_map instead.
+
+## Step 2 : DB stuff
+
+Still in [db.py](https://github.com/Khopa/dcs_liberation/blob/develop/game/db.py)
+
+Add your plane to the price map: 
+
+```python
+PRICES = {
+    # ...
+    A_4E_C: 8,
+    MB_339PAN: 6,
+    # ...
+```
+
+Also add it to the list and maps: ```UNIT_BY_TASK```, ```PLANE_PAYLOAD_OVERRIDES```, and if relevant in the lists : ```CARRIER_CAPABLE```, ```LHA_CAPABLE```
 
 ## Step 3 : Liberation flight planner database setup : 
 
+Open [ai_flight_planner_db.py](https://github.com/Khopa/dcs_liberation/blob/develop/gen/flights/ai_flight_planner_db.py)
+
+Add your plane to the lists it needs to be in, so DCS Liberation is aware of its capabilities : 
+
+**Example:**
+
+```python
+CAP_CAPABLE = [
+#   ....
+    Su_57,
+    F_22A,
+#   ....
+]
+```
+
 ## Step 4 : Create default payload
 
-## Step 5 : Create a faction that support the mods so it can be used
+See https://github.com/Khopa/dcs_liberation/wiki/Custom-Loadouts
+Create default loadouts for the new plane.
 
-## Step 6 : Add icons for the UI
+## Step 5 : Factions
+
+See https://github.com/Khopa/dcs_liberation/wiki/Custom-Factions and create a faction that support the mods so it can be used
+
+## Step 6 : Add icons for the UI [Optional]
+
+Add icons for the new plane there: https://github.com/Khopa/dcs_liberation/tree/develop/resources/ui/units/aircrafts/icons
+
+And a banner, there: https://github.com/Khopa/dcs_liberation/tree/develop/resources/ui/units/aircrafts/banners
 
 ## Step 7 : Playtest !
 
-Redo the data export thing (Step 1), every time said mod is updated
+Play a few missions with the plane, test as much cases as you can.
+
+## Step 8 : Release !
+
+## Step 9 : Maintenance !
+
+Redo the data export thing (Step 1), every time said mod is updated, if needed create new loadouts and account for new capabilities in db.
