+![Build Status](https://github.com/esphome/AsyncTCP/actions/workflows/push.yml/badge.svg)
-
 A fork of the [AsyncTCP](https://github.com/me-no-dev/AsyncTCP) library by [@me-no-dev](https://github.com/me-no-dev) for [ESPHome](https://esphome.io).
 
 ### Async TCP Library for ESP32 Arduino
 
-[![Join the chat at https://gitter.im/me-no-dev/ESPAsyncWebServer](https://badges.gitter.im/me-no-dev/ESPAsyncWebServer.svg)](https://gitter.im/me-no-dev/ESPAsyncWebServer?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
-
 This is a fully asynchronous TCP library, aimed at enabling trouble-free, multi-connection network environment for Espressif's ESP32 MCUs.
 
 This library is the base for [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer)
