 ## Incremental builds
 
-You can configure rustbuild to use incremental compilation with the
-`--incremental` flag:
+Incremental compilation is enabled by default in almost all of the config profiles
+under the `src/bootstrap/defaults`.
+
+In case if it's not enabled, you can configure rustbuild to use incremental
+compilation with the `--incremental` flag:
 
 ```sh
 $ ./x.py build --incremental
 ```
 
-The `--incremental` flag will store incremental compilation artifacts
+If you want to enable it once for all, you can apply the following configuration
+in your `config.toml`:
+
+```toml
+[rust]
+incremental=true
+```
+
+Incremental compilation will store compilation artifacts
 in `build/<host>/stage0-incremental`. Note that we only use incremental
 compilation for the stage0 -> stage1 compilation -- this is because
 the stage1 compiler is changing, and we don't try to cache and reuse
 incremental artifacts across different versions of the compiler.
 
-You can always drop the `--incremental` to build as normal (note that
-you will still be using the downloaded beta as your bootstrap).
