// @flow

/*
  On submit, this component calls publish, which dispatches doPublishDesktop.
  doPublishDesktop calls lbry-redux Lbry publish method using lbry-redux publish state as params.
  Publish simply instructs the SDK to find the file path on disk and publish it with the provided metadata.
  On web, the Lbry publish method call is overridden in platform/web/api-setup, using a function in platform/web/publish.
  File upload is carried out in the background by that function.
