The 0x team is excited to release version 0.0.4 of Launch Kit. This release allows for greater customisation, smaller containers and a number of improvements.
Custom Config
A config file can be used to modify the tokens, trading pairs, themes and general properties of Launch Kit frontend.
Below you will find the default config when starting Launch Kit

The new config and additional assets need to be mounted into the frontend container when using the docker-compose file generated by the wizard.

Smaller Containers
We have made a number of optimisations in the Launch Kit containers. This reduces the time to getting started by an order of magnitude.
| container | before size | after size |
|---|---|---|
| frontend | 621MB | 127MB |
| backend | 543MB | 91MB |
| total | 1,164MB | 218MB |
Getting started with a 30Mbps connection is down from over 6 minutes to less than a minute.
Persistent Backend
A Docker volume can now be attached to the backend to allow for persistent orders through restarts

Wizard
Upgrading to 0.0.4
If you have already used the wizard and wish to upgrade the docker containers, simply run docker-compose pull to pull the latest containers.
