Update source URL

Also removes the “legacy inventory” user-setting,
and defaults to 32 for inventory size.
I feel that the individual players shouldn’t be
able to tweak their inventory-size, that’s a
server-level sort of setting.

-This mod features a modern, powerful inventory menu with a good user experience.
-**`i4`** provides a rich [**API**](API.md) for mod developers who want to extend it.
+[i4](https://hak.xwx.moe/jadedctrl/minetest-i4) is an inventory system for Minetest with a focus on cohesion. It is a fork of [i3](https://github.com/minetest-mods/i3), the “next-generation inventory.” Primary differences to `i3` include an extended [API](API.md), more efficient use of screen-space, and general house-keeping.
 
-This mod requires **Minetest 5.6+**
+This mod requires Minetest 5.6+, as it uses newer additions to the formspec API.

-   - Crafting Guide (survival mode only)

-   - Quick Crafting
-   - 3D Player Model Real-Time Preview
-   - Isometric Map Preview
-   - Inventory Sorting (+ options: compression, reverse mode, automation, etc.)
-   - Item List Compression (**`moreblocks`** is supported)
-   - Item Bookmarks
-   - Waypoints
-   - Bags

+### Officially-supported mods
+These mods have menus built-into i4:

+* [**`awards`**](https://content.minetest.net/packages/rubenwardy/awards/)
+
+
+## Configuration
+There is currently two [`minetest.conf`](https://wiki.minetest.net/Minetest.conf) settings used by i4:
+
+* `i4_progressive_mode = false` — A discovery-based system, where the crafting guide only displays recipes whose components you have held before.
+* `i4_inventory_size = 32` — Players’ inventory-size. Defaults to 32 (or 36, if i3 was previously in use). Only accepted values are 32 and 36.
+
+
+## Notes
+i4 uses a larger inventory than the usual inventories in Minetest games.
+Thus, most chests will be unadapted to this inventory size.
+The i4  inventory is 9 slots wide by default, such as Minecraft.
+
+Please report bugs on the [bug tracker](https:///hak.xwx.moe/jadedctrl/minetest-i4/issues) — I don’t bite!
+
+
+### Recommendations
 To use this mod in the best conditions:
 
    - Use LuaJIT
    - Use the default Freetype font style
