 <p>Readium LCP is a relatively new eBook DRM. It's also known under the names "CARE DRM" or "TEA DRM". It does not rely on any accounts or key data that's difficult to acquire. All you need to open (or decrypt) LCP eBooks is the account passphrase given to you by the eBook provider - the very same passphrase you'd have to enter into your eBook reader device (once) to read LCP-encrypted books.</p>
 
+<p>This plugin no longer supports removing the Readium LCP DRM due to a DMCA takedown request issued by Readium. Please read the <a href="https://github.com/github/dmca/blob/master/2022/01/2022-01-04-readium.md">takedown notice</a> or <a href="https://github.com/noDRM/DeDRM_tools/issues/18">this bug report</a> for more information.</p>

+This file used to contain code to remove the Readium LCP DRM
+from eBooks. Unfortunately, Readium has issued a DMCA takedown 
+request, so I was forced to remove that code:

+https://github.com/github/dmca/blob/master/2022/01/2022-01-04-readium.md
+
+This file now just returns an error message when asked to remove LCP DRM.
