 ## jadx-string-decoder
 
-A JADX plugin that detects likely Base64-encoded string constants during decompilation and annotates them with a decoded comment inline.
+A JADX plugin that detects likely encoded string constants during decompilation and annotates them with decoded comments inline.
+
+### Features
+
+**Base64 string detection** — scans string constants in method bodies, and field initializers. When a string looks to be Base64 encoded, a `// b64: <decoded>` comment is added next to it.
+
+**Byte array string detection** — scans `byte[]` fields initialised with literal byte arrays. When the bytes decode as valid UTF-8 with sufficient printable characters, a `// bytes: "<string>"` comment is added.
 
-Install using location id: `github:nklapste:jadx-string-decoder`
+### Installation
+
+In jadx-gui: **Plugins → Install plugin** and enter the location id:
+
+```

+jadx plugins --install "github:nklapste:jadx-string-decoder"
+```
+
+### Example output
+
+```java
+// b64: Hello, World!
+private static final String ENCODED = "SGVsbG8sIFdvcmxkIQ==";
+
+void example() {
+    decode(new String[]{"eHBvc2Vk", "ZnJpZGE=", "Z3Vt"}); //
+    // b64[0]: xposed
+    // b64[1]: frida
+    // b64[2]: gum
+}
+
+// bytes: "Hello, World!"
+private static final byte[] MSG = {72, 101, 108, 108, 111, 44, 32, 87, 111, 114, 108, 100, 33};
