+### Coverage reports
+
+On the frontend, the lcov and HTML files are generated as normal, however on the backend, the folders are tested separately. The command `yarn coverage:backend` will concatenate the lcov files and also generate an HTML file. However, this provess requires `lcov` to be installed on a user's computer. On Apple, you can use Homebrew - `brew install lcov`. On a Windows machine, you will likely have to use WSL.
