+`CYPRESS_RUN_BINARY` should be a path to an already unzipped Cypress binary executable.
+The Cypress commands [open](./command-line#cypress-open), [run](./command-line#cypress-run) and [verify](command-line#cypress-verify)
+will then launch the provided binary.
+
+The following example [cypress run](./command-line#cypress-run) commands assume that you have first
+downloaded the Cypress binary to the default `Downloads` directory of your operating system.
+
+Depending on how you then unzip the downloaded Cypress binary `cypress.zip` file,
+using a CLI command or alternatively a GUI interface,
+the directory structure may include one additional top-level directory named `cypress`,
+which you may need to add to the path defined by `CYPRESS_RUN_BINARY`.
+
+If available, use the following to avoid the additional top-level directory level:
+
+```shell
+unzip -q cypress
+```
+
+:::note
+
+The examples below are for npm.
+If you are using Yarn or pnpm as package manager, replace `npx` with `yarn` or `pnpm` as appropriate.
+See [How to run commands](./command-line.mdx#How-to-run-commands).

+:::tip
 
-We recommend **not exporting** the `CYPRESS_RUN_BINARY` environment variable,
-since it will affect every cypress module installed on your file system.
+Cypress assumes that `CYPRESS_RUN_BINARY` points to a writeable directory structure so that it can save and re-use
+the results of verifying the Cypress binary.
+If you encounter a `permission denied` failure message from [cypress verify](./command-line.mdx#cypress-verify),
+you may be able to work around the failure by setting the environment variable `CYPRESS_SKIP_VERIFY` to `true`.
