 ## [How to get ready](#codex-testnet-starter)
 When starting the Testnet Starter for the first time, (or restarting after a long pause) please keep in mind:
 - Your local Geth node will need time to sync.
-- Codex should automatically wait until Geth is ready. However, in some situations Codex will attempt to start too soon and promptly crash. This is a known issue. When this happens, please manually restart Codex's container when your Geth node is synced.
+- Geth checker will wait until Geth is in sync and only then Codex will start.
 
 Before you can use the marketplace functionality of Codex, you will need to obtain some tokens in the testnet.
