+# atlas plugin
+
+[Atlas](https://atlasgo.io) (database schema migration CLI) plugin for
+[proto](https://github.com/moonrepo/proto).
+
+Resolves versions from Atlas's [git tags](https://github.com/ariga/atlas) and downloads
+the matching build from [atlasbinaries.com](https://atlasbinaries.com). This is the EULA
+flavor; its CockroachDB driver and `docker://` dev database require `atlas login`.
+
+## Installation
+
+Atlas is not built into proto, so register this plugin, pin a version, then install:
+
+```shell
+proto plugin add atlas "https://raw.githubusercontent.com/Genesis-Embodied-AI/proto-plugins/main/atlas/plugin.toml"
+proto pin atlas latest --resolve
+proto install atlas
+```
