+<ul>
+<li>[x] Kernel compiles (LineageOS)</li>
+<li>[x] Booting the system</li>

+<h3>What doesn't work well</h3>
+<ul>
+<li>I had to disable -Werror in order to compile the kernel</li>
+<li>Screen is laggy</li>
+<li>
+<p>initfs hook</p>
+</li>
+<li>
+<p>Splash screens don't work and I cannot get framebuffer working in initramfs</p>
+</li>
+<li>Screen is black after I've entered the password. Workaround:</li>

+<ul>
