+## Adding Content
+While games can be added to the server without them, it is recommended adding some signature DAT files beforehand to allow for better matching of ROM to game.
+
+These signature DAT files contain a list of titles with hashes for many of the ROM images that have been found by the community.
+
+Currently only TOSEC is supported, though more will be added.
+
+### Adding signature DAT files
+1. Download the DAT files from the source website. For example; from https://www.tosecdev.org/downloads/category/56-2023-01-23
+2. Extract the archive
+3. Copy the DAT files to ~/.gaseous-server/Data/Signatures/TOSEC/
+
+### Adding game image files
+1. Ensure your game image file is unzipped, and clearly named. Attempting a search for the game name on https://www.igdb.com can help with file naming. If a hash search is unsuccessful, Gaseous will fall back to attempting to search by the file name.
+2. Copy the file to ~/.gaseous-server/Data/Import
+
+Image to game matching follows the following order of operations, stopping the process at the first match:
+### Get the file signature
+1. Attempt a hash search
+2. Attempt to search the signature database for a rom matching the file name - sometimes the hash can not be matched as a highscore table for example was saved to the image
+3. Attempt to parse the file name - clues such as the extension being used to define which platform the file belongs to are used to create a search criteria
+
+### Create a list of search candidates
+Before beginning, remove any version numbers.
+1. Add the full name of the image
+2. Add the name of the image with any " - " replaced by ": "
+3. Add the name of the image with text after a " - " removed
+4. Add the name of the image with text after a ": " removed
+
+### Search IGDB for a game match
+Loop through each of the search candidates searching using:
+1. "where" - exact match as the search candidate
+2. "wherefuzzy" - partial match using wildcards
+3. "search" - uses a more flexible search method
+
+Note: that if more than one result is found, the image will be set as "Unknown" as there is no way for Gaseous to know which title is the correct one.
