 ## Mod requirements
 * For a mod to be listed, it needs to have a regular release (so not a prerelease) with exactly 1 recognised attached asset.
 * That asset can be either a dll if the mod doesn't have any other files, or a zip archive.
-* If the zip contains a folder named Plugins, the manager will unzip it to Gamecraft's directory instead of the Plugins directory.
+* If the zip contains a folder named Plugins, the manager will unzip it to Techblox's directory instead of the Plugins directory.
 * The mod dll must use the same name as the repository, including casing. The manager will rename single dlls automatically but can't handle zipped mods with different names.
 * If you have any other files as part of the release, the mod one (that needs to be downloaded to the game) must have the same name as the repository.
 * The release tag must be the same as the assembly version of the mod with an optional `v` prefix. It can also have a `-preview` suffix if it **only** works with preview versions of the game
 * Add the mod to the list at https://git.exmods.org/ExMods/html-site/src/branch/master/site/mods/modlist.tsv
+
+### Examples
+* For a mod named ExampleMod that also needs ExampleDll to work: zip the mod and the dll up in an archive named ExampleMod.zip and make sure the dll is also named ExampleMod.dll
+* For a mod named ExampleMod that needs to add an asset to the game, put the dll in a Plugins directory and the asset where it should be in the game and zip that together (Plugins/ExampleMod.dll and TechbloxPreview_Data/...)
+* For a mod named ExampleMod that has a separate app for it in the same repository or you want to attach something else in the release, *just do it:* as long as the zip is named ExampleMod.zip the mod manager will (only) download that zip
+* If you only have a single dll, it can be named anything, though why would you not name it the same?!
