 ```
+
+## compiling it with CI
+
+1. enable CI test in your forked repo : 
+   at https://github.com/username/perl/settings/actions set `Allow all actions and reusable workflows`
+   and `Read and write permissions`. Don't forget to click `save` at both section.
+2. Or create a new branch directly on binary-com/perl repo
+3. create a branch whose name include a perl version `perl-x.yy.zz`, e.g. `upgrade/perl.5.38.2`
+
+Then CI will download and compile perl and push it to your branch
