+## Minimum Supported Rust Version (MSRV)
+
+This library should compile with any combination of features with Rust 1.61.0.
+
+To build with the MSRV you will need to pin dependencies as follows:
+
+```shell
+# required for sqlite feature, hashlink 0.8.2 has MSRV 1.61.0
+cargo update -p hashlink --precise "0.8.1"
+# tokio 1.30.0 has MSRV 1.63.0
+cargo update -p tokio --precise "1.29.1"
+```
