-This action allow user to deposit lp token in the farm. User must send tokens to the farm's genesis address. It's fund will be hold by the contract and could be reclaimed using `claim` action when the end_timestamp is over.
-A user can deposit multiple time in the same farm with different duration of lock (level)
+- `level`: Determine the lock duration
 
-- Lock `end_timestamp` Unix: seconds since epoch
+This action allow users to deposit LP tokens in the farm. Users must send LP tokens to the farm's genesis address. Users may deposit multiple times. Deposits may be merged together for optimisation.
+
+note: `max` can be used when there is less than 3 years remaining to ensure the lock ends with the farm's end.
 
 ```elixir

+claim(identifier :: string)
 ```
