 # PeerTube Performances Test Kit
 
 Scripts to generate video files and live streams for performance testing of PeerTube
+
+## Dependencies
+These scripts rely on ffmpeg to generate the videos files and RTMP streams.
+Tested with ffmpeg versions:
+- 4.1.6
+- 4.2.4
+
+# Mains scripts
+There are 4 main scripts : 
+- gen_pattern_sine.sh
+    generate video file with static pattern, time overlay (seconds elapsed from start) and sine wave stereo audio
+- gen_random_noise.sh : 
+    generate video file with random video, time overlay (seconds elapsed from start and local timestamp) and sine wave stereo audio
+- stream_pattern_sine.sh : 
+    send live stream and save a copy to file with static pattern, time overlay (seconds from start) and sine wave audio
+- stream_random_noise.sh : 
+    send live stream and save a copy to file with random video, time overlay (seconds elapsed from start and local timestamp) and sine wave audio
+
+Run the scripts with no paramters for help.
+
+The "random_noise" scripts are designed to produce video streams that are very hard to encode. These are to test worst case scenarii
+
+The "pattern_sine" scripts produce video streams that are lighter to process (use less CPU to encode on peertube side) and compress to a smaller size.
+
+# Helper scripts
+The other scripts are helpers that are just sortcuts to call the main scripts with some pre-devfined parameters values. The names of these scripts should be self explanatory :
