how to add events.md

const { Client } = require('discord.js');

module.exports = {
    name: 'interactionCreate', // name of events 
    /**
     * @param { Client } client client use
     */
    async run(interaction, client) {  
            // your code what to do with that event 
    }
};

interaction will be the event paramaters u get from it, like if event is guildMemberAdd then u will get member as a paramater if its memberupdate or any thing which gives u 2 value/paramater from event then it will be always at first and client will be always at last in params value aka

async run(oldPresence, newPresence, client){
    // here memberpresence update  event have 2 parameters so it will be like this  any thing but client will be at last of it and if it get switch then it will property will change so ...
} 

your events goes inside src/events/any_folder_if_u_have/cmd_name.js like if its client event then its inside src/events/client/ eg src/events/client/ready.js
