1. Load your world in offline mode (or the F11 debug menu will not work nor will your local mod). Make sure it is Creative mode with Copy/Paste enabled.
   
2. Create a ship you want to use.
   
   • Make sure it is powered by a partially or fully charged battery and/or reactor with Uranium ingots in it (Use SHIFT+F10 to spawn items if needed).
     
   • Make sure any items you want are included such as cargo contents and ammo.
     
   • Make sure a beacon exists and is enabled. Set broadcast radius to 10000. The name is not important because it will be set elsewhere.
     
   • In the Info tab, give your ship a name. The filename will reflect this name as well. Example: Apophis Carrier
3. In the Control Panel of the ship, select all components (Left-Click top and then SHIFT+Left-Click bottom) and set the Owner as Nobody
   
4. Exit the ship and look/aim at the ship and press CTRL+C to copy it. Press ESC to cancel the duplicate as it is not needed.
   
5. Press F11 to bring up the debug menu and click the link called Export clipboard to file
   
6. While we are here, take a picture of your ship.
   
   • Press 0 to clear what you are holding in your hand.
     
   • Press TAB to remove the GUI interface.
     
   • Arrange the best position to view your ship in the light and have it take up the entire screen.
     
   • Press F12 to take a Steam Screenshot and go through the steps to save the image to your PC somewhere. Might even take several screenshots such as the inventory, other sides, cockpit view, etc.

1. Click Start -> Run and type %appdata% and press ENTER
   
2. Find and double-click the SpaceEngineers folder.
   
3. Find and double-click the Mods folder.
   
4. Right-click on an empty area and create a new folder with the name of your mod.
   Example: HL NPC Cargo Ships
   
5. Double-click the newly created folder.
   
6. Right-click on an empty area and create a new folder called Data
   
7. Double-click the Data folder.
   
8. Right-click on an empty area and create a new folder called Prefabs

1. Move your exported ship to the Prefabs folder of your mod location.
   Example Source: %appdata%\SpaceEngineers\Export\Apophis Carrier.sbc
   Example Target: %appdata%\SpaceEngineers\Mods\HL NPC Cargo Ships\Data\Prefabs\Apophis Carrier.sbc
   
2. To make sure there are no problems with spaces in the filename, rename the file to remove all spaces.
   Example: ApophisCarrier.sbc
   NOTE: The actual name of the file is not referenced anywhere. The key reference is the SubtypeId inside the file.
   
3. Edit the file using a text editor like Notepad or Notepad++ and search for <SubtypeId> and remove any spaces in the name and add a by line to ensure it is unique among all mods. This value must match the <Prefab> key in SpawnGroups.sbc which is covered later.
   Example: <SubtypeId>ApophisCarrier-by-LHammonds</SubtypeId>

1. Use one of the screenshots you made earlier or a collage image and place it in the root of your mod folder and rename the file to thumb
   Example: thumb.jpg
   
2. Edit the image and resize it to be no larger than 300 wide or 300 high and save in .jpg format with at least 75% compression ratio. This will keep the overall size of the mod very small. The goal is to have a "preview" image...not a high-resolution image...we will add those later and keep it separate from the mod download.

1. Copy the SpawnGroups.sbc file from <Space Engineers game location>\Content\Data\SpawnGroups.sbc to <Your Mod Folder>\Data\SpawnGroups.sbc
   
2. Using a text editor, edit SpawnGroups.sbc in your mod folder
   NOTE #1: This file contains NPC Cargo Ships, derelict ships and derelict stations. The derelicts are unpowered, not moving and has "IsEncounter" variable set to true.
   NOTE #2: We are going to remove all SpawnGroups referenced in this file except for one and use it as a template for our own. The NPC Cargo Ships are located at the bottom. We will keep the one called "Commercial Freighter"
   
3. There are several ship definitions which are surrounded by <SpawnGroup> and </SpawnGroup> tags. Delete all but one ship definition.
   
4. With only one ship left defined, change <SubtypeId> to be unique to your ship. It can be called anything but needs to not match the same as any other SubtypeId in this file (including any other mods that add NPC cargo ships). However, it can match the exact same key as defined in your ship file.
   Example: <SubtypeId>ApophisCarrier-by-LHammonds</SubtypeId>
   
5. The main variables are as follows:
   
   • TypeId = SpawnGroupDefinition (Leave this as is)
     
   • SubtypeId = Identifier for your ship. Must be unique and not match any vanilla NPC ships nor other mods.
     
   • Icon = Textures\GUI\Icons\Fake.dds (Leave this as is)
     
   • Frequency = 1.0 (The rate this ship will show up in relation to other NPC cargo ships. 1.0 = rare, 2.0 = medium, 4.0 = frequent, etc.)
     
   • Prefab SubtypeId = ApophisCarrier-by-LHammonds (Set this to match the SubtypeId field in your ship file. Example: ApophisCarrier-by-LHammonds)
     
   • Position X, Y, Z = 0.0 (Leave these as is)
     
   • Speed = 10.0 (Set however you like but keep in mind that anything above 5.0 can be difficult for players due to desync issues on multiplayer servers at the moment)
     
   • BeaconText = Your Ship Name (Set how you want the ship to appear on radar)
     
6. Save and close the file.

1. Create a new custom world, set Online Mode to offline, make sure Cargo Ships is enabled, click on Mods and your mod should be listed with a white folder-like icon to the left of it. Add your mod and click OK. The folder icon means it is a local mod. Once published, you will see another entry with a Steam logo next to it meaning it is a WorkShop mod.
   
2. Click OK to load the world.
   
3. Wait for NPC cargo ships to show up. Once you see one of yours spawn, you are good-ta-go! If in a hurry, you could edit the frequency and temporarily bump it up to something like 50 to make them have a higher chance of spawning above the default ships but make sure to set the values back before publishing.
   
4. Try out the ship for a while and make sure things like Ownership are set to you, cargo contents are correct, fuel levels are right, etc.

[code]cout << "Hello World!";[/code]

1. Start Space Engineers and click New World, Custom World
   
2. None of the settings matter. Just click the Mods button and select your local mod in the list (should have a white folder next to it)
   
3. Click the Publish button and then click Yes stating that you agree to giving over your 1st born child.
   
4. Place a checkmark in the Other category and click OK
   
5. Mod Published - Click OK to see it pulled up in the in-game workshop
   
6. You can now edit the description, add those high-resolution images and videos.

1. Create a new creative mode world using the "Empty World" scenario as a base configuration. Give it a name, load it up, save the world, exit Space Engineers.
   
2. Start SEToolbox and open/load the world you just created.
   
3. From the menu, click Import -> Sandbox Content files (.sbc) and then find/load the ship file you want to import.
   
4. Do this for each ship you want to import, then save and close SEToolbox.
   
5. When you load the world in-game, they will all be fairly close to you and spread out a little.
