+# Serum Multisig Setup
+
+## Deploy Multisig program:
+
+1. Download the program binary code from the GH Release: [https://github.com/project-serum/multisig/releases/tag/v0.9.0](https://github.com/project-serum/multisig/releases/tag/v0.9.0)
+
+```bash
+# Create the program keypair used as multisig's `program-id`
+solana-keygen new --outfile multisig-program.json
+
+# Check the binary size in bytes
+wc -c target/verifiable/serum_multisig.so
+  234536 target/verifiable/serum_multisig.so
+
+# Deploy the program, but add some buffer to the size as `max-len` (~2x)
+solana program deploy \
+  --keypair PATH_TO_KEYPAIR/id.json \ # optional, custom keypair
+  --program-id multisig-program.json \
+  --max-len 500000 \
+  target/verifiable/serum_multisig.so
+```
+
+## Initialize Multisig state acc (wallet):
+
+```bash
+# Use the create command of the gauntlet-serum-multisig package/executable
+yarn gauntlet-serum-multisig create --network=[NETWORK] --threshold=[THRESHOLD] [OWNERS...]
+```
+
+This will output 2 important addresses:
+
+1.  Multisig State Acc Address: where the multisig program data for this instance is stored (e.g., threshold, owners, proposals).
+    - Set this address as an env variable into `PATH_TO_GAUNTLET/networks/.env.network` as `MULTISIG_ADDRESS`
+2.  Multisig Signer Address: Address that will sign any transaction the multisig executes.
+    - This is the address we need to transfer ownership to, as all proposals will be executed virtually by this signer.
+    - This signer address is autogenerated from the Multisig Program ID and State Acc Address (can be derived/found at any time).
