Is your feature request related to a problem? Please describe.
No its not really a problem, but I think the Page of your Client-Addon requires some more explanation, like how to access the GUI etc. Currently I tried it out and its unusable for me due to lack of description, can't find any tutorials or help in your wiki, except that vague page: (It tells a bit, also that it adds GUI and some commands)
https://github.com/ForgeEssentials/ForgeEssentials/wiki/FE-Client-mod

Describe the solution you'd like
A Clear description on that Page, about all commands for that Client-Addon
https://github.com/ForgeEssentials/ForgeEssentials/wiki/FE-Client-mod

Describe alternatives you've considered
Use commands instead of the Addon, since its ususeable without description

Additional context
N/A

The client addon does need some documentation. However, in it's current state it is rather limited anyway.
I will see about adding some documentation to it at a later date.
