• Run this command in cmd or powershell heroku stack:set container -a appname, where appname is replaced with your Heroku app's name.- Create a new heroku app.
• Open the Settings tab on heroku and insert your API access token with bot:play scopes enabled in the Config vars field in the format LICHESS_BOT_TOKEN:API-ACCESS-TOKEN, where you replace API-ACCESS-TOKEN with your API Access token.
• Go to the Deploy tab and click Connect to GitHub.
• Click on search and then select your fork of this repository.
• Then Enable Automatic Deploys and then select the main branch (which is already done by default usually) and Click Deploy.
• Once it has been deployed, go to Resources tab on heroku and enable dynos. (Do note that if you don't see any dynos in the Resources tab, then you must wait for about 5 minutes and then refresh your heroku page.)
• NOTE if your bot stopped playing but online go to heroku and click on more > restart all dynos

You're now connected to lichess and awaiting challenges! Your bot is up and ready!
