Pokemon-go – How is the skillset of an evolution being chosen

Pokémon GO's database is based on Niantic's portal database for Ingress, which is currently not accepting new requests for more locations while they review the process.

If you want to see every current PokéStop, download and register for Ingress, then go to https://www.ingress.com/intel

There are some plugins you can download to facilitate the discovery of Stops and Gyms based on that information (and even help updating the ones that still aren't registered as either).

Keep in mind that, while every PokéStop and Gym are based on Ingress Portals, not every Portal will be a PokéStop or Gym.

There are no fights before player level five. You will also not receive Potions and Revive items from Pokéstops before this level, as you have no use for them without access to fights.

Evolving can be helpful, although Combat Power (CP) is generally a much stronger indicator of success in a Gym battle. Additionally, you will want to build your team to combat the enemies' strengths and weaknesses. This follows the typical format from earlier Pokémon games (e.g. Fire is super effective against Grass, Electric is super effective against Flying, Water is super effective against Fire, etc.). This web page should be a useful resource in helping you build a strong team to counter your opponents' types.

The gym system is a little complicated, but in essence, by fighting an enemy gym you reduce that gym's prestige (until eventually your team takes it over). Once your team takes over a gym, you can increase its prestige by continuing to battle there. If there is an empty slot in the gym, you should be able to station a Pokémon there, which will help defend it from enemy teams. Once every 21 hours you can claim a reward for holding a gym by going into the shop menu and tapping the shield icon in the top right. The reward for each Pokémon that is still stationed in a gym is 500 Pokédust and 10 Pokécoins.
