+        blek! File has an API for uploading files via cURL.
+        To upload a file via cURL, follow these instructions:
+    </p>
+    <p>
+        To upload a file, POST it like this:
+        <a href="#" class="copy-btn" data-clipboard-text="curl -X POST {{env.instanceurl}}/curlapi/upload -F'file=@file.txt' -F'tos_consent=on'">

+        curl -X POST {{env.instanceurl}}/curlapi/upload -F'file=@file.txt' -F'tos_consent=on'
+    </div>
+    <p>
+        To add a password, do it like this:
+        <a href="#" class="copy-btn" data-clipboard-text="curl -X POST {{env.instanceurl}}/curlapi/upload -F'file=@file.txt' -F'filename=uwu' -F'tos_consent=on' -F'named=on'">

+    <p>
+        Note that the
+        <span class='code-inline'>named=on</span>
+        switch is required.
+        Its needed because the curl API is basically a wrapper of
