blogger.com
In short: Blogger (blogger.com) accepts blog links. It is free to submit, takes a moderate amount of preparation, and scores 46/100 on our impact ranking (long tail).
Create official your tool update/tutorial blog if needed.
Avoid duplicate content; canonical strategy needed.
Priority is later, which sets the band. It is free and moderate to complete, which adjusts it within that band. The score ranks your queue — it is not a measure of domain authority.
