While i do understand that giving the format is giving away a lot of hint, i suggest to expose in some way the description on how to insert the answer for the challenges.

In the challenge https://shellterlabs.com/en/questions/shx-12/shx12-b0mb/ , for example i found the numbers, and i got the "bomb defused" message, but still have no idea on how to input the numbers in the answer box to solve the challenge.

Thank you for the fun i'm having, though.
