F-Droid server ask for Android Software Development Kit

Reading the docs it says we can skip the Android SDK installation but then when following the other steps and run fdroid init I get:

2024-01-04 03:31:49,137 ERROR: No Android SDK found!
2024-01-04 03:31:49,137 ERROR: You can use ANDROID_HOME to set the path to your SDK, i.e.:
2024-01-04 03:31:49,138 ERROR:  export ANDROID_HOME=/opt/android-sdk
Enter the path to the Android SDK () here:

2024-01-04 03:31:59,078 CRITICAL: Android SDK path '' does not exist!

How can I successfully skip Android SDK? I wont build any app.

Thank you.

see Installing the Server and Repo Tools | F-Droid - Free and Open Source Android App Repository maybe?

fyi Android SDK - Wikipedia

Thank you, ended up installing the SDK, the doc should be updated because it is needed to init the repo.
