 ## Develop & test
 
-Make sure to run `npm run build` once, then run
-
-```bash
-npm run link-watch
-```
-
-In another shell, `cd` to your test studio and run:
-
-```bash
-npx yalc add sanity-plugin-asset-source-unsplash --link && yarn install
-```
-
-Now, changes in this repo will be automatically built and pushed to the studio,
-triggering hotreload. Yalc avoids issues with react-hooks that are typical when using yarn/npm link.
