 The assembler is written in about 400 lines, it's designed to help bootstrap the Uxn ecosystem and to demonstrate the concept of a personal one-page computer concept. The goal is for Driflim's source code to be released as a print-friendly document, along with its assembled hexadecimal data and the _napkin definition_ of the Uxn virtual machine.

 ## Build
 
 This assembler is written in the language it is assembling, creating a chicken-and-egg problem. You have two choices, download a pre-assembled [drifblim.rom](https://rabbits.srht.site/drifblim/drifblim.rom)(1300 bytes), or use [uxnasm.c](https://git.sr.ht/~rabbits/uxn/tree/main/item/src/uxnasm.c).

 _Drifblim is strong enough to lift Pokémon or people but has no control over its flight. This causes it to drift with the wind and end up anywhere._
 
+## Project Mode
+
+Drifblim allows for live-reloading when used as a `launcher.rom`(f4). To use this feature, you need to create a `.drifblim` file of 61 bytes to be loaded in the zero-page:
+
+- `00-2f`, source path.
+- `30-5f`, destination path.
+- `60`, non-zero values will also run the run on assembly.

+#### Extras

+- `unicycle.tal` Console REPL.
+- `bicycle.tal` [Graphical REPL](https://wiki.xxiivv.com/bicycle).
