+# ArtifactMenu
+
+This is a simple World of Warcraft add-on to automate opening the Artifact interface in the upcoming expansion *Legion*. It is my first add-on and was never intended to be particularly complex. The whole point is that:
+
+1. To open the Artifact interface, you must Shift+RightClick on your equipped Artifact weapon
+2. It is easier to type `/run SocketInventoryItem(16);`, if you can save it to a macro
+3. It is more intuitive to type `/am` or `/artifact` than the above macro
+4. Some artifacts are off-hands and require inventory slot #17
+
+This add-on will simplify all of that to just:
+
+* `/artifact`
+* `/am` (if you're lazy)
+* `/artifactmenu` (if you're forgetful)
