-To display a visit counter on your webpage, you'll need to edit your `index.html` file and insert a `<script>` tag that loads the counter.
+Image-digit hit counter for your tilde page. Drops in with one `<script>` tag and increments on each load.
 
-Type: `nano index.html` to open your file for editing.
+## Quick start
 
-Add the following line *exactly where you want the counter to appear*:
+Put this where you want the digits to render (footer is common):
 
 ```html
-<script src="https://counter.tilde.club/?page=homepage&user=yourname&style=57chevy"></script>
+<script src="https://counter.tilde.club/?page=home&user=<your_username>"></script>
 ```
 
-- Replace `homepage` with any identifier for the page you're tracking.
-- Replace `yourname` with your username or something unique to your site.
-- Replace `57chevy` with a different style if you'd like.
+## What to know
 
-Here’s an example:
+* Counts are keyed by **(page, user)**. Use a unique `page` per page (`home`, `about`, `guestbook`).
+* Digits are **zero-padded to 4** (e.g., `0042`).
+* **Counts every load** (not unique visitors).
+* Requires **JavaScript**.
+
+## URL parameters
+
+* `page` (required): letters/numbers/`._-` only.
+* `user` (required): your tilde username (no `~`).
+* `style` (optional): digit theme (default `web1`).
+* `ext` (optional): image extension (default `gif`).
+
+Example with options:
 
 ```html
-<p>Visitor count:
-<script src="https://counter.tilde.club/?page=homepage&user=alice&style=web1"></script>
-</p>
+<script src="https://counter.tilde.club/?page=about&user=<your_username>&style=7seg&ext=gif"></script>
 ```
 
-Once you’ve added the line, save and close the file using `CTRL+X`, then press `y` and `[Enter]`.
+## Available styles
 
-Refresh your site in your browser to see the counter.
+`57chevy`, `7seg`, `bbldotg`, `bellbtm`, `blgrv`, `cntdwn`, `computer`, `ds9`, `fdb`, `led`, `marsil`, `sbgs`, `web1`
 
-### Available Styles
+## Troubleshooting
 
-You can use any of these style names in the `style=` parameter:
-
-- `57chevy`
-- `7seg`
-- `bbldotg`
-- `bellbtm`
-- `blgrv`
-- `cntdwn`
-- `computer`
-- `ds9`
-- `fdb`
-- `led`
-- `links`
-- `marsil`
-- `sbgs`
-- `web1`
-
-Try different styles to see which one fits your site best.
-
-Note: The counter uses sessions and cookies to count *unique* visits per user every 24 hours (or whatever time is configured). Page refreshes won’t increase the count unless unique mode is off.
-
-If you need help or want a custom style added, reach out to the site admin.
-```
+* **No digits**: open the script URL directly—fix invalid `page/user` or typos.
+* **Broken images**: ensure `style` exists and `ext=gif`.
+* **Shared counts**: give each page a distinct `page` value.
