-There is a feature called `bin-features` which automatically includes all the necessary features
-required for building these tools.
+For convenience, a feature named `bin-features` is available which is a combination of the following:
+
+* `decimal` – support for decimal numbers
+* `metadata` – access functions metadata
+* `serde` – export functions metadata to JSON
+* `debugging` – required by `rhai-dbg`
+* `rustyline` – required by `rhai-repl`
