+1. First build and deploy serum dex to devnet (if you just want to use already deployed then skip this step)
+2. Go to blockworks-foundation/solana-flux-aggregator, Add the token pairs you want into config/setup.dev.json
+3. Run `yarn solink setup config/setup.dev.json`
+4. Make sure the feeds in solana flux aggregator can feed new tokens
+5. Add the oracle pubkeys found in deploy.dev.json into ids.json devnet.oracles
+6. Add the token mints to ids.json devnet.symbols
+7. Amend devnet.env and add new symbols
+8. List the new markets. For example:
+
+```
+source ~/mango/cli/devnet.env
+
+cargo run -- $CLUSTER list-market $KEYPAIR $DEX_PROGRAM_ID --coin-mint $BTC --pc-mint $USDT
+cargo run -- $CLUSTER list-market $KEYPAIR $DEX_PROGRAM_ID --coin-mint $ETH --pc-mint $USDT
+```
+
+9. Add the MarketState pubkeys to ids.json devnet.spot_markets
+10. go to blockworks-foundation/liquidator/crank.sh and add support for your new markets
+11. run crank.sh to run the cranks, for example
+```
+source crank.sh btc usdt
+source crank.sh eth usdt
+```
+12. Deploy new mango group for example:
+```
+CLUSTER=devnet
+KEYPAIR=~/.config/solana/id.json
+IDS_PATH=~/mango-client-ts/src/ids.json
+TOKENS="BTC ETH USDT"
+MANGO_GROUP_NAME=BTC_ETH_USDT
+BORROW_LIMITS="1.0 20.0 50000.0"
+
+cargo run -- $CLUSTER init-mango-group \
+--payer $KEYPAIR \
+--ids-path $IDS_PATH \
+--tokens $TOKENS \
+--mango-program-id $MANGO_PROGRAM_ID \
+--borrow-limits $BORROW_LIMITS
+```
