@sylock Looks like you'll need to run make docs. Also, please make sure to sign your commits by using the -s flag: git commit -asm "message"

[alexec]

make codegen needs running

[sylock]

I'm sorry but make codegen is still not working from my side:

• Do you have some documentation about how to setup properly a dev environment
• It would be nice to have an easier entry barrier to contributing, especially for documentation (I'm not a golang dev)

I'm sorry but make codegen is still not working from my side:

I tend to copy the patch and use git apply to update codegen when the CI prints the diffs.

[simster7]

@sylock I ran codegen for you
