+## `qmk find`
+
+This command allows for searching through keyboard/keymap targets, filtering by specific criteria. `info.json` and `rules.mk` files contribute to the search data, as well as keymap configurations, and the results can be filtered using "dotty" syntax matching the overall `info.json` file format.
+
+For example, one could search for all keyboards using STM32F411:
+
+```
+qmk find -f 'processor=STM32F411'
+```
+
+...and one can further constrain the list to keyboards using STM32F411 as well as rgb_matrix support:
+
+```
+qmk find -f 'processor=STM32F411' -f 'features.rgb_matrix=true'
+```
+
+**Usage**:
+
+```
+qmk find [-h] [-km KEYMAP] [-f FILTER]
+
+options:
+  -km KEYMAP, --keymap KEYMAP
+                        The keymap name to build. Default is 'default'.
+  -f FILTER, --filter FILTER
+                        Filter the list of keyboards based on the supplied value in rules.mk. Matches info.json structure, and accepts the formats 'features.rgblight=true' or 'exists(matrix_pins.direct)'. May be passed multiple times, all filters need to match. Value may include wildcards such as '*' and '?'.
