+# Zydis disassembler
+
+Zydis x64/x86 disassembler imported from github, see
+https://github.com/zyantific/zydis and https://github.com/zyantific/zycore-c.
+
+Zydis is MIT licensed code, see Zydis/LICENSE and Zycore/LICENSE.
+
+Sources here were taken from the tag/revision of Zydis that is recorded in the
+file imported-revision.txt.
+
+The file hierarchy of Zydis+Zycore has been flattened and processed as described
+in the script update.sh.
+
+## Integrating new versions of Zydis
+
+The procedure for pulling a new version is encoded in the script update.sh,
+which is to be run from the parent directory of zydis, ie, from js/src/. It
+will create a new zydis directory and pull new files from github into it,
+leaving the old zydis directory as zydis_old.
+
+It's not a given that the script will work out of the box for new versions of
+zydis or that the resulting files will build as-is. Buyer beware.
