 ## Development
 
 ### Prerequisites
 
-- [Go](https://go.dev/doc/install) 1.21+
-- [TinyGo](https://tinygo.org/getting-started/install/) 0.30+
+- [Go](https://go.dev/doc/install) 1.25+
 - [SQLC](https://sqlc.dev/) for database code generation
 - [Extism CLI](https://extism.org/docs/install) (optional, for testing)
 
 ### Building
 
 ```bash
-make build          # Build with TinyGo for wasip1
+make build          # Build WASM for wasip1
 make generate       # Regenerate SQLC database code
-make test           # Run tests (requires Go, not TinyGo)
+make test           # Run tests
 ```
 
 ### Testing the Plugin
 
+**CLI Testing:**
 ```bash
-extism call ./build/enclave.wasm generate --input '{"credential": "..."}'
-extism call ./build/enclave.wasm query --input 'did:sonr:abc123'
+extism call ./build/enclave.wasm generate --input '{"credential": "dGVzdA=="}' --wasi
+extism call ./build/enclave.wasm query --input '{"did": "did:sonr:abc123"}' --wasi
 ```
 
+**Browser Testing:**
+```bash
+make serve
+# Open http://localhost:8080/example/ in your browser
+```
+
+The browser test UI provides interactive testing of all plugin functions with real-time output.
