# Building ZMK for the BDN9
Some general notes/commands for building standard BDN9 layouts from the assembly documentation.
## Standard Build
```
west build -p -d build/bdn9 --board bdn9_rev2
```
## Encoder Notes
If you built your BDN9 with encoders, you'll need to change the following in your local BDN9 config or add them to the end of the file.
```
CONFIG_EC11=y
CONFIG_EC11_TRIGGER_GLOBAL_THREAD=y
```
Then, you'll want to uncomment the necessary encoder lines in your `bdn9_rev2.keymap`:
```
&sensors {
status = "okay";
sensors = <&left_encoder &mid_encoder &right_encoder>;
};
&left_encoder { status = "okay"; };
&mid_encoder { status = "okay"; };
&right_encoder { status = "okay"; };
```
And then add the correct `sensor-bindings` array to each keymap layer, e.g.:
```
sensor-bindings = <&inc_dec_kp PG_UP PG_DN &inc_dec_kp M_VOLU M_VOLD &inc_dec_kp C_PREV C_NEXT>;
```
