-CLI tools for interacting with the Gitea API. Use interactively to talk to your Gitea instance, or automatically via a CI/CD pipeline.
+A CLI tool for interacting with the Gitea API. List existing releases, create new ones, and attach release-items (files) to them. It can be used interactively as one publishes their work, or automatically as part of a CI/CD pipeline.
+
+## Why this thing exists
+
+This program exists because I find GitHub Actions to be an insufficient system. There is no official "release-attachment" workflow. I have to either make my own or find someone else's. Since there is no standard Workflow for this task, the [Gitea version](https://gitea.com/actions/gitea-release-action) has a different API. Since I can only use branches, tags, or exact commit hashes, my dependency resolution is often manual or happens in surprising ways (e.g.: force pushing a new version tag). Adjacent to this is the issue that lots of dependencies are "assumed" and cannot be named -- like how the Ubuntu base image contains NodeJS, even if I never ask to install it. Finally, I can't easily execute or re-execute the workflows. There is no "run Action" button and I can't run any of it from my dev machine.
+
+So I figured I'll make my own as a learning exercise and try to address as many of those problems as I can. The key is recognizing that a CI/CD platform needs a package manager. I like Debian, so I will stand on its package manager, although it might be better to pick NixOS or Gentoo. A GH Workflow which depends on this tool needs only to record it's name -- declarative build dependencies! This feature extends to the entire Debian container, automatically giving me full-system dependency knowledge. Updating the build environment is exactly like updating a normal Linux host because it *is* a normal Linux host. Lastly, it's also *a normal CLI program* so you can use it from your own dev workstation. There is no need for a "run Action" button.
