+## Requirements
+
+All the ohos targets of Tier 2 with host tools support all extended rust tools.
+(exclude `miri`, the support of `miri` will be added soon)
+
+### Host toolchain
+
+The targets require a reasonably up-to-date OpenHarmony SDK on the host.
+
+The targets support `cargo`, which require [ohos-openssl](https://github.com/ohos-rs/ohos-openssl).
+
 ## Setup
 
 The OpenHarmony SDK doesn't currently support Rust compilation directly, so
