@carlosmiranda We can do base on your idea, but it's not satisfied to me. We're trying to create a MkContents to converging to same function of RtContents. So ```update``` method should have all required parameters in API, not just ```content`` attr. We need to do it similar to RtContents does.
```
Name 	Type 	Description
path 	string 	Required. The content path.
message 	string 	Required. The commit message.
content 	string 	Required. The updated file content, Base64 encoded.
sha 	string 	Required. The blob SHA of the file being replaced.
branch 	string 	The branch name. Default: the repository’s default branch (usually master)
```
