+**Illegal instruction - core dumped**
+
+Bun currently only works on CPUs supporting the AVX2 instruction set.
+To run on older CPUs this can be emulated using Intel SDE, however bun won't be as fast as it would be when running on CPUs with AVX2 support.
+If you get this error while bun is initializing, you probably need to wrap the bun executable with intel-sde.
+
+**1.** Install intel-sde:
+   • Arch Linux: `yay -S intel-sde`
+   • Other Distros:
+```bash
+wget https://downloadmirror.intel.com/732268/sde-external-9.7.0-2022-05-09-lin.tar.xz -O /tmp/intel-sde.tar.xz
+cd /tmp
+tar -xf intel-sde.tar.xz
+cd sde-external*
+mkdir /usr/local/bin -p
+cp sde64 /usr/local/bin/sde
+cp -r intel64 /usr/local/bin/
+cp -r misc /usr/local/bin/
+```
+
+**2.** Add alias to bashrc
+   • `echo "alias bun='sde -chip-check-disable -- bun'" >> ~/.bashrc`
