 When running `yarn start` this routes through the CLI and eventually calls `yarn dev` with the proper arguments. This enables Cypress day-to-day development to match the logic of the built binary + CLI integration.
 
-If you want to bypass the CLI entirely, you can use the `yarn dev` task and pass arguments directly. For example, to headlessly run a project in a given folder, while trying to record to Cypress Cloud.
+CLI flags can be passed to `yarn` targets to control application behavior when running locally. For example, to headlessly run a project in a given folder, while trying to record to Cypress Cloud:
 
 ```text
-yarn dev --run-project /project/folder --record --key <key>
+yarn cypress:run --project /project/folder --record --key <key>
 ```
 
+Alternatively, you can run `yarn dev` at the root of this repository to bypass the CLI. This will launch "global" mode, where you can then select a project.

 #### Adding new Dependencies
 
 ⚠️ There is a [bug in yarn](https://github.com/yarnpkg/yarn/issues/7734) that may cause issues adding a new dependency to a workspace. You can avoid this by downgrading yarn to 1.19.1 (temporarily downgrade using `npx yarn@1.19.1 workspace @packages/server add my-new-dep1`).
