-## Before the First Prompt — Import Your Key
-
-Your AI will be running transactions on your behalf, but it should never touch your private key. Foundry's encrypted keystore handles signing locally — you import your key once, set a password, and from that point your AI just asks for the password when it needs to sign.
-
-Do this step yourself in a terminal **before** starting the prompts:
-
-```bash
-cast wallet import battlechain --interactive
-```
-
-You'll be asked to paste your private key and set an encryption password. The key is stored encrypted at `~/.foundry/keystores/battlechain` — your raw private key is never written to disk or passed to any tool.
-
-Verify it worked:
-
-```bash
-cast wallet list
-```
-
-You should see `battlechain` listed. From here on, your AI will prompt you for the password when it needs to sign a transaction — that's the only thing you need to provide.

 ## How This Works
 
 You're going to paste five prompts into your AI tool. Each one does a concrete thing: set up the project, deploy your contracts, create a Safe Harbor agreement, open for attack, then exploit the vault and collect the bounty.
 
-Your AI handles all the commands. You enter your keystore password when prompted — that's it.
+There is one thing your AI will **not** handle: importing your private key. That step is yours — your key should never be passed to any tool. Foundry's encrypted keystore takes care of signing locally, and we'll walk you through it after Prompt 1 once the tooling is installed.
 
 **Optional: give your AI a head start**

+## Import Your Key — Manual Step
+
+Now that Foundry is installed, you need to import your private key into its encrypted keystore. This is the one step your AI doesn't touch — your key stays on your machine and is never passed to any tool.
+
+Run this in your terminal:
+
+```bash
+cast wallet import battlechain --interactive
+```
+
+You'll be asked to paste your private key and set an encryption password. The key is stored encrypted at `~/.foundry/keystores/battlechain` — your raw private key is never written to disk.
