+# Zstd in the Linux Kernel
+
+This directory contains the scripts needed to transform upstream zstd into the version imported into the kernel. All the transforms are automated and tested by our continuous integration.
+
+## Upgrading Zstd in the Linux Kernel
+
+1. `cd` into this directory.
+2. Run `make libzstd` and read the output. Make sure that all the diffs printed and changes made by the script are correct.
+3. Run `make test` and ensure that it passes.
+4. Import zstd into the Linux Kernel `make import LINUX=/path/to/linux/repo`
+5. Inspect the diff for sanity.
+6. Check the Linux Kernel history for zstd. If any patches were made to the kernel version of zstd, but not to upstream zstd, then port them upstream if necessary.
+7. Test the diff. Benchmark if necessary. Make sure to test multiple architectures: At least x86, i386, and arm.
+8. Submit the patch to the LKML.
