How can I move forward to participate in GSOD as mentioned at https://wiki.list.org/DEV/SeasonOfDocs2019 ?
As mentioned in the google's guide
Discuss project ideas with open source organizations. You may discuss project ideas with any of the participating organizations. To make contact, use the organization's email address shown in the list of >participating organizations. Early discussions help you put together a good project proposal for submission to the Google program administrators >during the technical writer application phase. The initial project ideas may come from the ideas list that the organization has proposed. You may >propose your own ideas too.
Pick a project and start working on it Ask any doubt( related to project or general in this list by creating a new thread or commenting in a previous open one) Cheers!
