To avoid issues with installation it is necessary to install a compatible version of Yarn.
It was highlighted [here](https://github.com/polkadot-js/apps/pull/78) that Yarn 1.0 included workspaces, and we are successfully using Yarn 1.3.2 for Travis CI, so propose to request users to ensure they are using a version later than that to avoid and problems.
For instance, I was using Yarn 0.24.6 and it [wouldn't install the sub-package dependencies](https://github.com/polkadot-js/apps/pull/78) nor would it [run a necessary binary](https://github.com/polkadot-js/apps/issues/98), but after upgrading to Yarn 1.7.0 those issues were resolved.
