1. The target branch is failing probably because you changed it in the PR
2. Fix the conflicting file
3. You'll need to do some research. The project is not community based. It is targeting network engineers, NetOps, DevOps, SysAdmins & SysOps. Please find images and artwork in your next PR to address this. The images in this PR are inappropriate in the short term. They will need to be changed soon.

@palisadoes Hi, the image was totally random to get the same layout as Hasura Docs website. But since it is not appropriate, I have set the image transparent for the moment until the next PR. Conflicts are now resolved. Please let me know if anything else needs to be changed for this PR.
