 The main problem with traditional MMORPG's is people seeking power and while an offline game can provide this for everyone, an online game cannot. Pretty soon new players will avoid such MMORPG's and existing players will also dwindle. In my opinion there are 2 solutions, you could introduce a decay mechanic to overcome this, or concentrate your innovations and additions to make a more social game rather than a game for power hungry people. Originally I intended to add a lot more social integrations, for example browser notifications integrated to the social hub of the game and easy drop ins to friends playing the game etc. So making a more idle and more social game, with new custom art and a new direction could also be a good option, it's definitely the more serene option that anyone can pursue.
 
+## Code formatting
+
+This project uses [Eslint](https://eslint.org/) and [Prettier](https://prettier.io/).  
+For now, this is only used inside the game servers (`/node/` folder).  
+If you use VSCode, please install the recommended extensions for [eslint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) and [prettier](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode). The formatting will be automatically done on save.  
+If you have suggestions regarding the formatting, feel free to open an issue or discuss it on Discord. [Here is the history](https://discord.com/channels/238332476743745536/1163453037126357074) of the conversation regarding the formatting.  
+As you might notice, several eslint rules have been marked as warnings instead of errors. This is to allow a smooth and iterative transition. Make sure your new code respects the rules, even the warnings. If you want to submit a PR to fix a specific warning in a specific part of the code, feel free to do so.
