 3. Use artlav's [medet_arm](https://github.com/artlav/meteor_decoder) to generate a decoded dump and then a false color image
 4. Use dbdexter's [meteor_rectify](https://github.com/dbdexter-dev/meteor_rectify) to correct the visible deformation on Meteor images (wrong aspect ratio)

   - [Wiki](https://github.com/reynico/raspberry-noaa/wiki) is updated!
   - Audio files are stored on a RAMFS partition. Happen to had some glitches on image reception
 
-### Manual work

+### Install
+There's an [install.sh](install.sh) script that does everything at once. If in doubt, see the [Wiki's install and config page](https://github.com/reynico/raspberry-noaa/wiki/Initial-installation-and-configuration).
 
 ### Important notes
   - I tried to run this on a Raspberry PI Zero Wifi, no luck. Seems like it's too much load for the CPU. Running on a Raspberry PI 2+ is ok. See [Wiki's hardware notes page](https://github.com/reynico/raspberry-noaa/wiki/Hardware-notes).
