+First of all, these scripts helped me to record my first video.
+Here is my [youtube channel][beautemusculation] to see the result.
+
+# Scripts to record videos
+
+Both `record-audio.sh` and `record-video.sh` do exactly what their name is saying.
+These are simple ffmpeg calls.
+Their unique parameter is the output filename.
+
+Since I use them on OpenBSD the audio driver is sndio and not Alsa or OSS or PulseAudio or whatever.
+
+# Recording the camera
+
+I don't record my face from my camera in a separate video stream.
+I just display my camera feed in a window thanks to `camera.sh` and my whole screen is recorded with `record-video.sh.`.
+
+There are two optional parameters: brightness and saturation.
+
+Don't hesitate to tweak a bit this script: there are a few hardcoded ffmpeg parameters, such as a very low quality video size.
+
+# Synchronize audio and video
+
+The scrpt `sync.sh` is to include in your environment.
+It adds a few shell functions, using ffmpeg and mpv to help mixing and synchronizing audio and video.
+
+- stereo2mono: my first error was to record a mono input in stereo, so I had audio only on the left side.
+  This fixes the issue by removing the superflous empty track.
+  Side note: since then, `record-audio.sh` was corrected (see `-ac 1` option).
+- please_read: I'm like super lazy.
+  This launches mpv with both video and audio without having to specify both files and the mpv option.
+  Just read the source, the function is obvious.
+- avsync: this is the core function to synchronize audio and video.
+  Usage: `avsync video audio delay output`.
+- avs: did I mention I'm lazy?
+  This function is just me not wanting to type all `4` parameters for avsync.
+  Again, read the source code, it's obvious.
+
+# Forget about record-audio-and-video.sh
+
+This script _probably_ does work if your computer is powerful enough.
+That's not the case for mine.
