# How to start

> A couple of minutes to your first signals.

## Step 1. Grab your free key

<Steps>
  <Step title="Open the bot">
    Start [@usefulapp\_bot](https://t.me/usefulapp_bot) and type **/start**.
  </Step>

  <Step title="Subscribe to the channel">
    The bot asks you to subscribe to [@usefulsolana](https://t.me/usefulsolana) — subscribe, then tap **I subscribed**.
  </Step>

  <Step title="Get your FREE key">
    The bot sends a key valid for **30 days**. Copy it.
  </Step>

  <Step title="Log into the site">
    Open [site.usefulsol.fun](https://site.usefulsol.fun), paste the key and press **ACCESS**. The site remembers you — no need to paste it again.
  </Step>
</Steps>

## Step 2. Install the extension

The extension adds notifications, quick-buy and OG Finder on top of Axiom, GMGN and Terminal. It runs in Chrome and Chromium-based browsers — **Brave, Edge, Opera**.

<Steps>
  <Step title="Download the file">
    In the bot, type **/download** — it sends the latest `.zip`.
  </Step>

  <Step title="Load it into your browser">
    Unzip the file. Open the extensions page (`chrome://extensions`, or `brave://extensions`, `edge://extensions`), turn on **Developer mode** (top-right), click **Load unpacked** and pick the folder.
  </Step>

  <Step title="Sign in with your key">
    Open the extension popup, paste the **same key** and press **Save**. Pick the terminal (Axiom / GMGN / Terminal) where tokens should open.
  </Step>
