Install the iSign extension

This extension lets you sign iSign contracts digitally from other websites, without leaving them.

Not in the store yet

Installation steps(Chrome)

  1. 1

    Download the extension package

    Download the ZIP above and unzip it. Do not delete the unzipped folder — the browser runs the extension from it.

  2. 2

    Open chrome://extensions

    Type chrome://extensions in the address bar.

  3. 3

    Turn on “Developer mode”

    Turn on the “Developer mode” switch in the top-right corner.

  4. 4

    “Load unpacked”

    Click it and choose the unzipped folder. You are done when “iSign — Digital signature” appears in the list.

Manually installed extensions do not update themselves
When a new version is released, repeat the steps above or update from chrome://extensions.

After installing

The extension only activates on partner sites registered with iSign. The “Sign” button starts working there — it is normal that nothing appears on this page.
