 # i3
 
-#### A tiling inventory for Minetest
+[![ContentDB](https://content.minetest.net/packages/jp/i3/shields/title/)](https://content.minetest.net/packages/jp/i3/) [![ContentDB](https://content.minetest.net/packages/jp/i3/shields/downloads/)](https://content.minetest.net/packages/jp/i3/)
 
-**`i3`** is a tiling inventory for Minetest with a modern UI using the latest technologies of the Minetest engine.
-It offers everything what [**`craftguide`**](https://github.com/minetest-mods/craftguide) can do, with an inventory on top of that.
+#### **`i3`** is a next-generation inventory for Minetest.
 
-This inventory features a **Progressive Mode**.
-This mode is a Terraria-like system that shows recipes you can craft from items you ever had in your inventory.
-To enable it: `i3_progressive_mode = true` in `minetest.conf`.
+This inventory offers a slick, modern UI made with the latest technologies of the Minetest engine.
+**`i3`** provides a rich [**API**](https://github.com/minetest-mods/i3/blob/master/API.md) for mod developers who want to extend it.
 
-For developers, **`i3`** also has a [modding API](https://github.com/minetest-mods/i3/blob/master/API.md).
+This mod requires **Minetest 5.4+**
 
-This mod also supports [`3d_armor`](https://github.com/minetest-mods/3d_armor) for a nice player model preview.
+#### List of features:
+   - Crafting Guide (only in survival mode)
+   - Progressive Mode¹
+   - Quick Crafting
+   - Backpacks
+   - 3D Player Model Preview
+   - Inventory Sorting (alphabetical + item stack compression)
+   - Item Bookmarks
+   - Waypoints
+   - Item List Compression (**`moreblocks`** supported)
+
+**¹** *This mode is a Terraria-like system that shows recipes you can craft from items you ever had in your inventory.
+To enable it: `i3_progressive_mode = true` in `minetest.conf`.*
+
+
+#### This mod officially supports the following mods:
+   - [**`3d_armor`**](https://content.minetest.net/packages/stu/3d_armor/)
+   - [**`skinsdb`**](https://content.minetest.net/packages/bell07/skinsdb/)
+   - [**`awards`**](https://content.minetest.net/packages/rubenwardy/awards/)
+
+#### Recommendations
+
+To use this mod in the best conditions:
+
+   - Use LuaJIT
+   - Use a HiDPI widescreen display
+   - Use the default Freetype font style
+
+#### Notes
+
+`i3` uses a larger inventory than the usual inventories in Minetest games.
+Thus, most chests will be unadapted to this inventory size.
+The `i3`  inventory is 9 slots wide by default (without backpack), such as in Minecraft.
+
+Report any bug on the [**Bug Tracker**](https://github.com/minetest-mods/i3/issues).
