+## Getting Started
+
+Begin by building the assembler and emulator by running the build script.
+
+```
+./build.sh
+```
+
+You now have the assembler(`uxnasm`) and the emulator(`uxnemu`). To create a rom, from a [usm file](https://wiki.xxiivv.com/site/uxambly.html), use the following command. This example will create the `life.rom` from the `life.usm` uxambly file, point to a different file or folder to assemble a different rom. You can find additional roms [here](https://sr.ht/~rabbits/uxn/sources).
+
+```
+bin/uxnasm projects/demos/life.usm bin/life.rom
+```
+
+To launch the rom:
+
+```
+bin/uxnemu bin/life.rom
+```
+
 ## Emulator Controls
 
 - `ctrl+h` toggle debugger
