# Installing on a Moon
Requires base hash at least: `rd3oe`

## Create Moon
In your Urbit:
```
|moon
```
Copy the key and note the moon name.

## Install New `zuse.hoon`
```
./urbit -w $MOON_NAME -G $COPIED_KEY
```
The moon will compile and apply OTAs. After that is done, run:
```
|mount %
```

Back outside:
```
cd $BTC_AGENTS_DIR
./install-zuse.sh $MOON_PIER
```

In moon:
```
|commit %home
|reset
```

Install the rest of the files:
```
./install.sh $MOON_PIER
```

The kernel will recompile. Then test that the new `decompress-point` is included.
The below should yield: `0x3.30d5.4fd0.dd42.0a6e.5f8d.3624.f5f3.482c.ae35.0f79.d5f0.753b.f5be.ef9c.2d91.af3c`
