+## Julia versions
+
+Adjust `julia_version` environment variable as needed. Accepted are:
  - `nightly`: for latest [nightly build](https://julialang.org/downloads/nightlies.html).
  - `1`: for latest version 1 major release
  - x.y: for latest x.y minor release
  - x.y.z: for exact x.y.z release
+
+## Coverage
+
+The script supports automatic uploading of coverage statistics to various online services.
+
+### Codecov
+
+1. Enable [Codecov.io](https://codecov.io/) on the repository.
+2. Add a `codecov` environment variable.
+
+If the repository is private, you will need to provide a `CODECOV_TOKEN`, similar to Coveralls below.
+
+### Coveralls 
+
+1. Enable [Coveralls.io](https://coveralls.io/) on the repository.
+2. Copy the provided secret token.
+3. Encrypt the token at https://ci.appveyor.com/tools/encrypt
+4. Provide the encrypted token as a [secure environment variable](https://www.appveyor.com/docs/how-to/secure-files/#decrypting-files-during-an-appveyor-build) `coveralls_token` (see the example above).
