NPCs have been placed next to all Construction Trainers (who teach the camp knowledges) They will explain placement and guidelines to players.
Camps must be placed on ground that supports its layout configuration. This will be conveyed by seeing information in the chatbox regarding the "fitness" of the surrounding terrain If the terrain fitness is less than 400, the camp can be placed as long as it meets the additional requirements listed below.
Camps cannot be placed near harvest nodes, creatures (hostile or friendly, including your mount/vehicle) or other players. Once the camp is deployed, other players can then approach the camp.
Camps cannot be placed in PvP zones or near structures of any kind (entrances, buildings, rocks or trees)
