 ======Flashing my Lenovo x200 with Libreboot======
+<WRAP info smaller>
+This guide is fairly old (2020/2021) and I haven't had time to update it with any changes that Libreboot may require.
+Most of the steps will still be relevant but I suggest cross-checking with the Libreboot site for any necessary updates until I can update this guide.
+I apologize for any inconveniences this causes.
+</WRAP>
 I accidentally botched my original Libreboot flash during an update, so I decided to take some pictures and type this guide to hopefully help someone else.

 If you’re planning on using wifi, it is recommended to replace the factory Intel wifi chip. The factory chip requires proprietary software to work correctly, and we’re librebooting to rid our x200 of closed source software!
