+## Import AIM Smiley Packs
+
+AIM emoticons (also called smileys) are the graphics that appear when users send messages with specific codes like `:)`
+or `:D`. Retro AIM Server includes a BART import utility that allows you to import smiley pack collections.
+
+This guide shows you how to install a smiley pack available
+from [The Internet Archive](https://archive.org/details/aol_instant_messenger_smiley_packs).
+
+1. **Download Smiley Pack**
+
+   First download the smiley pack archive.
+
+   ```bash
+   curl -L -o aim_bart_emoticons.zip "https://archive.org/download/aol_instant_messenger_smiley_packs/aim_bart_emoticons.zip"
+   ```
+
+   Then extract the archive:
+
+   ```bash
+   unzip aim_bart_emoticons.zip
+   ```
+
+   This creates an `aim_bart_emoticons/` directory containing 86 files (1 per pack) with hash names like `0201D213A4`,
+   `0201D205C8`, etc.
+
+2. **Import Emoticons**
+
+   From the root of the Retro AIM Server repository, run the BART import script to upload the smiley pack:
+
+    ```bash
+    ./scripts/import_bart.sh -t emoticon_set -u http://localhost:8080 /path/to/aim_bart_emoticons
+    ```
+
+   Replace `/path/to/aim_bart_emoticons` with the actual path to your extracted directory.
+
+3. **Verify Import Success**
+
+   Check that all emoticons were imported successfully:
+
+   ```bash
+   curl "http://localhost:8080/bart?type=1024"
+   ```
+
+4. **Send an Emoticon**
+
+   After importing, you can test the emoticons in AIM clients by sending messages with emoticon codes. For example, the
+   classic smiley emoticon can be tested with:
+
+   ```
+   <font sml="KwAAAeQ=">:)</font>
+   ```
+
+   This code references the smiley pack with hash `2B000001E4` that should now be available in your server.
