+### Optionally provide a starting channel number

+By using the `START` env var when starting the docker container, you can tell it to start channel numbers with this value. Original Pluto channel numbers will be added to this, keeping all of the channels in the same order they are on Pluto.

+You should use a starting number greater than 10000, so that the channel numbers will be preserved but not conflict with any other channels you may have.

+For example, channel 345 will be 10345. Channel 2102 will be 12102.
