+## Optional Pixabay music download
+
+If the input folder has no audio file, movmaker can download one random track from Pixabay Music.
+
+Save your Pixabay API key in either an environment variable:
+
+```bash
+export PIXABAY_API_KEY='your_key_here'
+```
+
+or in a local config file:
+
+```bash
+mkdir -p ~/.config/movmaker
+echo 'PIXABAY_API_KEY=your_key_here' > ~/.config/movmaker/pixabay.env
+chmod 600 ~/.config/movmaker/pixabay.env
+```
+
+The default music search query is:
+
+```text
+cinematic punk rock
+```
+
+Override it with:
+
+```bash
+python3 movmaker.py input --music-genre "upbeat rock"
