+Run the script below to start docker off building `llvmdev` base from the current state of the source tree:
+
+- 32-bit linux: `./buildscripts/manylinux_2_17/docker_run_x32.sh build_llvmdev.sh`
+- 64-bit linux: `./buildscripts/manylinux_2_17/docker_run_x64.sh build_llvmdev.sh`
+- aarch64 linux: `./buildscripts/manylinux_2_17/docker_run_aaarch64.sh build_llvmdev.sh`
+
+The conda packages will be stored into `<llvmlite_source_root>/docker_output`
+
+Note: the `docker_output` location can be used as a local conda channel.
+
+Finally, upload the conda package to the numba channel under the "manylinux_2_17" label:
+
+`anaconda upload -u numba -l manylinux_2_17 <filepath>`
