I can see you already have an account on our GitLab : Carles Barrobés · GitLab
Unfortunately most of the things are documented in french. In Duniter documentation (https://duniter.org/wiki/duniter-v2/) you will find a list of all calls and basic stuff about polkadotjs app (you can use any nodes listed in About the ĞDev category.
But that would be a very good contribution to gcli: improve command line documentation and create a user documentation on duniter.org. If you are interested in this, I can seed this so you fill more confortable to explain what you understand in a documentation.
Basically there are two levels of documentation:
- technical documentation that goes to the repo and assume that the user knows the context, it can be added to duniter website as external documentation
- user documentation which takes a more pedagogic approach and give more context about what’s being done, this one is written directly on duniter.org
