+### Information Page Handler
+Want to add some information about a block or item without making a massive tooltip for it? You can add information about any block or item by registering it in the Information Handler.
+
+Information page(s) are displayed when either the uses or recipes of a matching item are searched. All matching items will cycle at the top of the information page.
+
+Your mod can call:
+```java
+FMLInterModComms.sendMessage("NotEnoughItems", "addItemInfo", nbt);
+```
+Where nbt is an NBTTagCompound formatted as described below.
+
+| Tag              | Type                       | Description                                                                                                                                                                                                                |
+|------------------|----------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `filter`         | String                     | A string filter to match what items should return this information page.<br/>modname:itemname, metadata, Ore Dictionary tags, and regex can all be used. The full format may be seen in `config/NEI/collapsibleitems.cfg`. |
+| `page` / `pages` | String / String NBTTagList | The actual text to display. See below for differences between single and multi-page messages.<br/>Both formats will automatically translate provided strings.                                                              |
+
+#### Single Page Format
+
+Use the `"page"` string tag when you only want to add one page of information:
+```java
+NBTTagCompound tag = new NBTTagCompound();
+tag.setString("filter", "minecraft:log 3");
+tag.setString("page", "Exotic wood found in tropical climates.");
+
+FMLInterModComms.sendMessage("NotEnoughItems", "addItemInfo", tag);
+```
+
+#### Multiple Page Format
+
+Use the `"pages"` tag as an `NBTTagList` of strings when you want more than one page:
+```java
+NBTTagCompound tag = new NBTTagCompound();
+tag.setString("filter", "minecraft:diamond_sword");
+
+NBTTagList pages = new NBTTagList();
+pages.appendTag(new NBTTagString("A powerful melee weapon."));
+pages.appendTag(new NBTTagString("Can be enchanted for extra effects."));
+
+tag.setTag("pages", pages);
+
+FMLInterModComms.sendMessage("NotEnoughItems", "addItemInfo", tag);
+```
+* Each list entry is one page.
+* Pages will appear in NEI with buttons to scroll through them.
+
+#### Item Matching
+
+All items that match `filter` will show your information page. See `config/NEI/collapsibleitems.cfg` for the full filter format.
+
+#### Item Information Config File
+
+If you're a modpack creator and want to make custom item information pages, they can easily be added in `config/NEI/informationpages.cfg`, which has a few more examples.
+
 ## Other items of note:
 
 * Remove TMI style
