I just published this walk-through video on how to install a local copy of bch-dex, to sell SLP tokens via the DEX. This is the self-hosted version, so you do not need to ask permission or sign up for any accounts.
I'll be adding this video to the README for the bch-dex, as well as the different documentation sites like slp-tokens.com and dex-docs.psfoundation.info
