 # [WIP] lighthouse_go
 
+Uses `github.com/fluxrpc/solana-go` v0.1.9 and requires Go 1.26.4 or newer.
 
+Binary serialization uses `github.com/fluxrpc/solana-go/binary`. Create codecs
+with `binary.NewEncoder(nil)` and `binary.NewDecoder(data)`, then call the
+bindings' `MarshalWithEncoder` and `UnmarshalWithDecoder` methods. Instruction
+payload decoders consume parameters only; `lighthouse.DecodeInstruction` consumes
+the full instruction, including its one-byte discriminator. Instruction IDs and
+`BaseVariant.TypeID` are now `uint8`; explicit dispatch replaces the old variant
+registry. Golden tests cover byte compatibility for all 18 instruction types.
+
+The service and generated bindings accept Flux public keys and return Flux
+instructions. Use `lighthouse.DecodeInstruction` directly; Flux does not provide
+the previous SDK's global instruction decoder registry. `EncodeToTree` remains
+available with plain-text labels; the previous SDK-specific `TextEncode` method
+has been removed.
+
+The bindings were adapted from anchor-go output. When regenerating from
+`lighthouse.json`, preserve the Flux imports, explicit binary codecs, instruction
+dispatch, account accessors, and local tree formatting helpers.
+
+Run `go test ./...` for tests. Live RPC tests require `RPC_URL`; simulation tests
+also require `TEST_KEYPAIR` pointing to a Solana keypair file. These can be set in
+the environment or `.env`; tests skip when the required configuration is absent.
+The offline Flux transaction test is `go test . -run TestFluxInstructionTransaction`.
