+On supported platforms, `--enable-rjit` is set by default. You usually don't need to specify this.
+You may still manually pass `--enable-rjit` to try RJIT on unsupported platforms.

 If you see an "RJIT bindgen" GitHub Actions failure, please commit the `git diff` shown on the failed job.
 
 For doing the same thing locally, run `make rjit-bindgen` after installing libclang.
 macOS seems to have libclang by default. On Ubuntu, you can install it with `apt install libclang1`.

+This dumps all JIT code. You need to install libcapstone before configure.
 
-* `--rjit-dump-disasm`: Dump all JIT code.
-* `--rjit-stats`: Print RJIT stats.
