@ -195,11 +195,9 @@ You'll want to navigate to the `keyboard/<project_name>/` folder by typing, like
#### config.h
The first thing we're going to want to modify is the `config.h` file. On line 32 and 33, you'll see `MATRIX_ROWS` and `MATRIX_COLS` - set both these variables to however many rows and columns you have on your keyboard.
The first thing you're going to want to modify is the `config.h` file. Find `MATRIX_ROWS` and `MATRIX_COLS` and them to match the dimensions of your keyboard's matrix.
On line 38 and 39 you'll see the `COLS` and `ROWS` definitions - this is where you'll enter the pins you used, in order (left-to-right when looking at the top of the keyboard, but right-to-left when looking at the bottom).
There are some other variables that you'll be able to modify (lines 23-29), but it's not necessary to do that now (or ever, really).
Farther down are `MATRIX_ROW_PINS` and `MATRIX_COL_PINS`. Change their definitions to match how you wired up your matrix (looking from the top of the keyboard, the rows run top-to-bottom and the columns run left-to-right). Likewise, change the definition of `UNUSED_PINS` to match the pins you did not use (this will save power).
