+## Slidingwindow mode
+
+Setting the `--step` argument to `0` enables the sliding window mode:
+
+```java
+ ./stream -m ./models/ggml-small.en.bin -t 6 --step 0 --length 30000 -vth 0.6
+```
+
+In this mode, the tool will transcribe only after some speech activity is detected. A very
+basic VAD detector is used, but in theory a more sophisticated approach can be added. The
+`-vth` argument determines the VAD threshold - higher values will make it detect silence more often.
+It's best to tune it to the specific use case, but a value around `0.6` should be OK in general.
+When silence is detected, it will transcribe the last `--length` milliseconds of audio and output
+a transcription block that is suitable for parsing.
+
+## Building
+
 The `stream` tool depends on SDL2 library to capture audio from the microphone. You can build it like this:
 
 ```bash
