+This module overrides the upstream CMake `FindOpenSSL` module with few
+customizations:

+
+## Customizing search locations
+
+To customize where to look for the OpenSSL package base
+installation directory, a common `CMAKE_PREFIX_PATH` or
+package-specific `OPENSSL_ROOT` variable can be set at
+the configuration phase. For example:
+
+```sh
+cmake -S <source-dir> \
+      -B <build-dir> \
+      -DCMAKE_PREFIX_PATH="/opt/OpenSSL;/opt/some-other-package"
+# or
+cmake -S <source-dir> \
+      -B <build-dir> \
+      -DOPENSSL_ROOT=/opt/OpenSSL \
+      -DSOMEOTHERPACKAGE_ROOT=/opt/some-other-package
+```
