 Unison Codebase UI
 ==================
-
-[![CI](https://github.com/unisonweb/codebase-ui/actions/workflows/ci.yml/badge.svg)](https://github.com/unisonweb/codebase-ui/actions/workflows/ci.yml)
-
-Running Development Server
---------------------------
-
-🔔 You should only need to run the UI development server if you're contributing to the UI. If you just want to run the UI to see your Unison codebase, it should either come pre-installed with `ucm` or if you built from source can be downloaded with a script: `./dev-ui-install.hs` from the `unison` repository ([Running Unison](https://github.com/unisonweb/unison/blob/trunk/development.markdown#running-unison)).
-
-1. Start `ucm` (the executable is `unison` instead of `ucm` if you built the [unison repository](https://github.com/unisonweb/unison) from source) in headless mode: `ucm headless`, and copy the API URL (this URL
-   is uniquely generated by `ucm` at start-up) from the `ucm` start-up output
-   (`ucm` also outputs a UI URL, but this isn't used when developing for the
-   UI/running the UI from this repository).
-
-2. Make sure the latest dependencies are installed with by running `npm install`
-
-3. Start the Unison Share dev server with: `API_URL="<API URL FROM UCM>" npm run start:unisonShare` or the Unison Local dev server with: `API_URL="<API URL FROM UCM>" npm run start:unisonLocal`
-
-4. Visit `http://localhost:1234` in a browser.
-
-Adding new Icons
-----------------
-
-To add new icons, copy the SVG markup to a new function in `/src/UI/Icon.elm`
-following the convention seen there of other icons. The color (`fill` or
-`stroke`) of the shape must be
-[`currentColor`](https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/color).
