+Build the library first:
 ```bash
-# Build the library first
-cargo build --release
+cargo build --release -p dojo-uniffi
+```
+
+#### Swift, Kotlin, Python (Built-in)
 
+```bash
 # Generate Swift bindings (iOS/macOS)
 cargo run --bin uniffi-bindgen-swift --release -- \
-    target/release/libdojo_c.dylib bindings/swift --swift-sources
+    target/release/libdojo_uniffi.dylib bindings/swift --swift-sources

+```
+
+#### C# and Go (External Generators)
+
+C# and Go bindings use external tools. Install them first:
+
+```bash
+# Install external binding generators (one-time setup)
+./scripts/install_bindgen_tools.sh
+```
+
+Then generate bindings:
+
+```bash
+# Generate C# bindings
+./scripts/build_csharp.sh
+
+# Generate Go bindings
+./scripts/build_go.sh
+
+# Or generate all bindings at once
+./scripts/build_all_bindings.sh
+```
+
+**Manual installation:**
+
+```bash
+# C# (requires uniffi-bindgen-cs)
+cargo install uniffi-bindgen-cs --git https://github.com/NordSecurity/uniffi-bindgen-cs --tag v0.10.0+v0.29.4
+
+# Go (requires uniffi-bindgen-go)
+cargo install uniffi-bindgen-go --git https://github.com/NordSecurity/uniffi-bindgen-go --tag v0.4.0+v0.28.3
 ```
 
 See [`src/uniffi/README.md`](src/uniffi/README.md) for detailed UniFFI documentation.
