 Check out the [asdf](https://github.com/asdf-vm/asdf) readme for instructions on how to install and manage versions of other tools.
 
 When installing Gradle using `asdf install` if you not wish to have it check the package signature for whatever reason, you can set `no` using `export GRADLE_SIGNATURE_CHECK=no` example:
-```
 
+```sh
 export GRADLE_SIGNATURE_CHECK=no 
-
 ```
+
+If you want to use a custom distribution url, for example in a corporate setting you can set this:
+
+```sh
+export GRADLE_DISTRIBUTION_URL=https://services.gradle.org/distributions
+```
+
 Observation:
 
 * `GRADLE_SIGNATURE_CHECK` - `yes` (for yes, check the signature) is the default
