 ### Using a local installation of `litestream`
 
 If you are not able to use the vendored standalone executables (for example, if you're on an unsupported platform), you can use a local installation of the `litestream` executable by setting an environment variable named `LITESTREAM_INSTALL_DIR` to the directory containing the executable.
 
 For example, if you've installed `litestream` so that the executable is found at `/usr/local/bin/litestream`, then you should set your environment variable like so:
 
-``` sh
+```sh
 LITESTREAM_INSTALL_DIR=/usr/local/bin
 ```
 
 This also works with relative paths. If you've installed into your app's directory at `./.bin/litestream`:
 
-``` sh
+```sh
 LITESTREAM_INSTALL_DIR=.bin
 ```

 The gem also provides a default initializer file at `config/initializers/litestream.rb` that allows you to configure these four environment variables referenced in the configuration file in Ruby. By providing a Ruby interface to these environment variables, you can use any method of storing secrets that you prefer. For example, the default generated file uses Rails' encrypted credentials to store your secrets:
 
 ```ruby
-litestream_credentials = Rails.application.credentials.litestream
-Litestream.configure do |config|
-  config.replica_bucket = litestream_credentials.replica_bucket
-  config.replica_key_id = litestream_credentials.replica_key_id
