Mod Description
video link SKSE - Skyrim Script Extender Extends scripting capabilities of Vanilla Skyrim. Nearly essential since it is required by so many great mods such as SkyUI, Immersive HUD, Convenient Horses, Trade and Barter, etc. After SKSE is installed, the game must always be launched by running skse_loader.exe instead of TESV.exe in order to take advantage of the SKSE capabilities i.e. mods such as SkyUI that rely on SKSE will not work properly if you simply launch the game with the default launcher even if SKSE is installed correctly. (watch "How to launch the game with SKSE running").

video link Mod Organizer The recommended and more capable alternative to Nexus Mod Manager. Like NMM, it also integrates with Nexus for easy 1-click downloading but it isolates installed mods and uses virtual directories so nothing in your actual data directory is ever overwritten. Lets you create multiple profiles to manage different mod collections, ini files, characters, and save games. Slightly higher learning curve than Nexus Mod Manager but it will save a lot of time in the long run.

video link Nexus Mod Manager A slightly easier-to-use alternative to Mod Organizer. Nexus Mod Manager is a free utility that makes it fast and easy to download, install, update and manage mods. A very good mod manager for beginning modders.

video link LOOT A one-click program that quickly optimizes mod load order to avoid conflicts. Essential for anyone who mods. Used in conjunction with Mod Organizer, Nexus MOd Manager or Wrye Bash. Always run LOOT every time you add or remov a mod.

video link Wrye Bash If you have multiple mods that alter the same leveled lists (e.g. 2 mods that add armor or weapons), only the last one in your load order will actually be found in loot unless you create a Bashed Patch. Use Wrye Bash to create a Bashed Patch (Bashed Patch.esp).

Bashed Patch - An ESP file named "Bashed Patch.esp" that is auto-generated by Wrye Bash. When Bashed Patch.esp is placed at the bottom of your load order and enabled, it will merge leveled lists from 2+ conflicting mods so that new/modified items will appear in leveled lists (loot) within the game. Items from different mods are merged by marking each mod with one or more Bash Tags.

Bash Tags: - Within Wrye Bash, mods are marked with various bash tags to guide Wrye Bash in how to properly construct a Bashed Patch.ESP appropriate for your current list of mods. (A new bashed patch should be created when adding or removing mods). Run Loot (see utility above) to sort your mods in the correct order. Once sorting is completed, Loot will automatically tag mods with the appropriate Bash Tag/s (i.e. all mods that alter loot lists). Common Bash Tags:
   Delev - Delete leveled list items (i.e. instructs Wrye Bash to delete entries from Leveled Actor, Leveled Item and Leveled Spell Records)
   Relev - Relevel leveled list items (i.e. instructs Wrye Bash to relevel entries in the Leveled Actor, Leveled Item and Leveled Spell Records)
