 - This extension started off with the VS Code hello world test sample.
-- Then it was extended to have source control button and commit flow, based on [Git Semantic Commit](https://github.com/nitayneeman/vscode-git-semantic-commit). See [LICENSE-source](LICENSE-source).
+- I then used parts of [Git Semantic Commit](https://github.com/nitayneeman/vscode-git-semantic-commit), especially the `Git` API for adapting `status` from `diff`.
+- There is also a much simpler and more relevant extension - [https://github.com/srmeyers/git-prefix](https://github.com/srmeyers/git-prefix) or the fork [d3skdev/git-prefix](https://github.com/d3skdev/git-prefix). This pushes a message to the commit message UI box and allows manual overrides, which is a flow I like. This could work with the existing Semantic Git Commit extension if that message is kept when opening up the picklist for type. Also I have a plan to add semantic prefix using my own logic, for some cases.
 - The [parse-git-status](/src/generate/parse-git-status) module was based on [jamestalmage/parse-git-status](https://github.com/jamestalmage/parse-git-status), but with a different approach and some functionality left out (ignored and untracked files which would not be committed) and with added TS types so it can be used here.
