Rename keyboard-level readmes to lower-case (#10759)

This is the recommendation in the [PR
Checklist](https://docs.qmk.fm/#/pr_checklist?id=keyboard-prs) and it
will make working with them easier in the CLI/API/etc.

+# Terrazzo
+
+![Terrazzo](https://i.imgur.com/W91ixck.jpg)
+
+Terrazzo is a 40% pro micro keyboard kit with a fun, hot-swapable LED module. It is offered in both staggered and ortholinear variations, each with multiple layout options. A left hand macro column has 4 positions for switches or rotary encoders. 
+
+Extended layout options and multiple encoder support will require use of an Elite-C controller. Key switch support is MX soldered only.
+
+* Keyboard Maintainer: MsMustard, [Anne Demey](https://github.com/ademey) 
+* Hardware Supported: Terrazzo v1 & v2 PCB in staggered and ortholinear
+
+Make example for this keyboard (after setting up your build environment):
+
+- `make terrazzo:default` Split spacebar staggered layout
+- `make terrazzo:ortho` 2 x 2u spacebar ortho layout
+- `make terrazzo:ortho_mit` 2u spacebar ortho layout
+- `make terrazzo:ortho_all` All 1u ortho layout
+

+## Custom Keycodes
+
+Terrazzo has several custom keycodes for LED control.
+
+| Key | Description |
+|-----|-------------|
+| `TZ_NXT` | Next Animation |
+| `TZ_PRV` | Previous Animation |
+| `TZ_OFF` | LED Off |
+
+## LED Animations
+
+LED animations for Terrazzo are reactive to keyboard input. Each key press or encoder turn increments an internal counter, looping through the number of individual LEDs. 
+
+This counter (`terrazzo_led_index`) is used as a seed for the animation functions, along with a boolean indicating the direction. Turning the encoder counter-clockwise, or pressing backspace will decrement the counter, allowing for animations to reverse or display alternative frames.
+
+The current animations are:
+
+- DINO: It's like your internet went out
+- DOT: Just a single led at a time, for debugging
+- HEART: Love you too
+- OUTRUN: Driving into the sunset
+- PAC_DUDE: Vintage arcade fun
+- STRIPES: Just a nice gradient
+- WPM_CHART: 2 digit readout with lights indicating speed, each pixel = 2 wpm
+
+Not all animations are enabled by default. You can enable or disable animations in the `config.h` file to limit firmware size.
+
+```
+// #define DISABLE_TERRAZZO_EFFECT_STRIPES
+// #define DISABLE_TERRAZZO_EFFECT_DINO
+// #define DISABLE_TERRAZZO_EFFECT_OUTRUN
+#define DISABLE_TERRAZZO_EFFECT_PAC_DUDE
+#define DISABLE_TERRAZZO_EFFECT_HEART
+// #define DISABLE_TERRAZZO_EFFECT_WPM_CHART
+#define DISABLE_TERRAZZO_EFFECT_DOT
+```
+
+## Microcontroller Support
+
+Terrazzo is designed for use with a Pro Micro (or compatible, like Bit-C), or an Elite-C. The extra pinouts of an Elite-C are required for the ortho MIT and ALL layouts and multiple encoders. By default the firmware is set up for an Elite-C. For a Pro Micro some changes to `config.h` are needed.
+
+Change number of rows from 9 to 8.
+```
+#define MATRIX_ROWS 8
+```
+
+Change pinouts, Pro Micro does not have the "F0" pin.
+```
+#define MATRIX_ROW_PINS { D2, D7, E6, B4, B5, B6, B2, B3 }
+```
+
+Set encoder to just top or bottom position.
+```
+#define ENCODERS_PAD_A { C6 }
+#define ENCODERS_PAD_B { D4 }
+```
+
+## Encoder Setup
+
+Terrazzo has 4 positions for encoders in the left-hand column. Up to 3 may be used at a time, but this requires the extra pins of an Elite-C. Please refer to `config.h` for examples of pin configurations.
+
+The default keymaps are setup for one encoder. Encoders can change behavior based on the current layer. Here, on the "NAV" layer, the encoder changes volume instead of scrolling.
+
+```c
+void encoder_update_user(uint8_t index, bool clockwise) {
+    terrazzo_scroll_pixel(clockwise);
+    switch(get_highest_layer(layer_state)) {
+      case _NAV:
+        // Change volume when on nav layer
+        clockwise ? tap_code(KC_AUDIO_VOL_UP) : tap_code(KC_AUDIO_VOL_DOWN);
+        break;
+      default:
+        // Default encoder behavior of Page Up and Down
+        clockwise ? tap_code(KC_PGDN) : tap_code(KC_PGUP);
+        break;
+    }   
+}
+```
+
+If using multiple encoders, the `index` param can be used to distingish which is providing input.
+
+```c
+void encoder_update_user(uint8_t index, bool clockwise) {
+    terrazzo_scroll_pixel(clockwise);
+    switch(index) {
+      case 0:
+        clockwise ? tap_code(KC_PGDN) : tap_code(KC_PGUP);
+        break;
+      case 1:
+        clockwise ? tap_code(KC_AUDIO_VOL_UP) : tap_code(KC_AUDIO_VOL_DOWN);
+        break;        
+    }
+}
+```
