 management. That must be done in the config. An example config is provided.
 
+# Things to know before using the helper
+
+Sometimes if a package prompts a user to select between alternate package
+dependencies, makechrootpkg will fail to select one by default (it will
+constantly output "y" to stdin when a selection requires an integer). This means
+you will need to check the logs as it is building a package to make sure this
+kind of soft-lock doesn't happen. Use `tail -f LOG_FILE.log` for example. If
+such a soft-lock happens, Ctrl-C the helper, and explicitly set a dependency in
+the TOML config file in a "other\_deps" array for the package like so:
+
+    [[entry]]
+    name = "sway-git"
+    aur_deps = [
+        "wlroots-git",

+    other_deps = [
+        "mesa"
