+# Custom Emojis
+
+Put your custom PNG or GIF files in this directory, or in `png/` and `gif/`
+subdirectories.
+
+The filename without extension is used as the emotion name. Directory names are
+not part of the emotion name, so `png/neutral.png` is loaded as `neutral`.
+
+The display code looks up images by names such as:
+
+- `neutral.png` or `neutral.gif`
+- `happy.png` or `happy.gif`
+- `sad.png` or `sad.gif`
+- `angry.png` or `angry.gif`
+- `thinking.png` or `thinking.gif`
+- `confused.png` or `confused.gif`
+- `surprised.png` or `surprised.gif`
+- `shocked.png` or `shocked.gif`
+- `sleepy.png` or `sleepy.gif`
+- `relaxed.png` or `relaxed.gif`
+
+Recommended minimum set:
+
+- `neutral`
+- `happy`
+- `thinking`
+- `sad`
+- `angry`
+
+If an emotion-specific image is missing, the firmware falls back to `neutral`
+before using the built-in icon. Do not add both `png/happy.png` and
+`gif/happy.gif`; only one image per emotion should be used.
+
+After adding or replacing files, run a full flash so the assets partition is
+updated:
+
+```bash
+idf.py flash
+```
