# Building ZMK for the Tidbit
Some general notes/commands for building standard Tidbit layouts from the assembly documentation.
## Standard "Non Dense" Build
```
west build -p --board nice_nano -d build/tidbit/default -- -DSHIELD=tidbit
```
## Dense "19 keys" Build
```
west build -p --board nice_nano -d build/tidbit/19_key -- -DSHIELD=tidbit_19key
```
## LED Notes
If you built your tidbit without the LEDs *and* are using a Nice!Nano board, you'll need to add the following at the *end* of your local tidbit config.
```
CONFIG_ZMK_RGB_UNDERGLOW=n
CONFIG_WS2812_STRIP=n
```
## Encoder Notes
If you built your tidbit without encoders, you'll need to add the following at the *end* of your local tidbit config.
```
CONFIG_EC11=n
CONFIG_EC11_TRIGGER_GLOBAL_THREAD=n
```
## OLED Builds
If using an OLED screen you'll need to include the following at the *end* of your local tidbit config.
```
CONFIG_ZMK_DISPLAY=y
```
