+# This patch resolves a local dependency conflict between `mbedtls` and `mbedtls-selftest`.
+# Both of these crates require the native library `mbedtls-sys-auto`.
+# By default, Cargo chooses the `mbedtls-sys-auto` version from crates.io for `mbedtls-selftest`,
+# which conflicts with the local `mbedtls-sys-auto` used by `mbedtls`.
+# This patch ensures the local `mbedtls-sys-auto` is used for both crates.
