-### filter_audio
-This step is  best done before compiling toxcore.
-
-Now you can either follow the instructions at
-https://github.com/irungentoo/toxcore/blob/master/INSTALL.md#unix or use the
-[`bootstrap.sh`](/bootstrap.sh) script. The script will automatically download
-and install `toxcore` and `libfilteraudio`:
-```bash
-## in qTox directory
-./bootstrap.sh # use -h or --help for more information
-
-```
-If you've used script, you can skip directly to [compiling qTox](#compile-qtox).
-
-If you want to compile and install it manually:
-```bash
-git clone https://github.com/irungentoo/filter_audio
-cd filter_audio
-make -j$(nproc)
-sudo make install
-```
