Tools are the first section, not the whole plan

Software was the easiest part to catalogue, so it went first. The sections below are what the rest of the job looks like, and they open in the order people ask for them. Nothing in them is written yet. All of them are open for suggestions, and what gets suggested decides what is in them when they open.

Know when a section opens

One email when new tools go into the directory or a section opens. That is the whole thing. It is not a newsletter, there is nothing to read weekly, and there is no pitch at the bottom.

Your address is not shared or sold, and it is not passed to any tool listed here. It is used for that one email and nothing else. Reply to any of them to be removed.
