+# libunbound ![Maven Central Version](https://img.shields.io/maven-central/v/dev.rushii/libunbound)
+
+Android native library for dynamically interacting with compiled Hermes.
+This is mainly intended to be used by Discord RNA client mods.
+
+## Usage
+
+`build.gradle.kts`:
+
+```kotlin
+repositories {
+  mavenCentral()
+}
+
+dependencies {
+  implementation("dev.rushii:libunbound:1.0.0")
+}
+```
+
+Use after Hermes (`libhermes.so`) has been loaded into the process:
+
+```kotlin
+// Returns the HBC version supported by the loaded runtime
+// https://github.com/discord/hermes/blob/0.76.2-discord/include/hermes/BCGen/HBC/BytecodeVersion.h#L23
+LibUnbound.getHermesRuntimeBytecodeVersion()
+
+// Check to verify whether some bytes are hermes bytecode (possibly inaccurate)
+LibUnbound.isHermesBytecode(/* bytes */)
+```
