+### Linking packages from this monorepo to another projects
+
+`pnpm` has a nested structure for packages, which is not compatible with the classic `yarn`, because `yarn` using a flat
+structure, but you can force `pnpm` to use a flat structure too by setting the `--shamefully-hoist` flag.
+
+For example, if you want to link the `tswebextension` package from this monorepo to the
+[browser extension project][browser-extension] which are using `yarn`, you can follow these steps:
+
+1. Install packages in this monorepo with `pnpm install --shamefully-hoist`.
+1. Go to the *tswebextension* package directory: `cd packages/tswebextension`, and run `yarn link`.
+1. Go to the *browser extension* project directory: `cd /path/to/browser-extension`,
+   and run `yarn link @adguard/tswebextension`.
+   This way, the browser extension project will use the linked package from this monorepo, instead of the published one
+   from the npm registry.
+
+If the other project are using `pnpm`, you can use [`pnpm link`][pnpm-link] to connect the packages locally.
+For more details, please check the pnpm documentation.
