# Build the web server
In order to build the web server we will be using the [ESPAsyncWebServer library](https://github.com/me-no-dev/ESPAsyncWebServer) that is perfect for building an Asynchronous web server.
#### Install [ESPAsyncWebServer library](https://github.com/me-no-dev/ESPAsyncWebServer)
We need to install it manually by following the steps below:
1. Download the zip folder of the [ESPAsyncWebServer library](https://github.com/me-no-dev/ESPAsyncTCP/archive/master.zip)
2. Unzip the folder.
3. Rename your folder from ~~ESPAsyncWebServer-master~~ to *ESPAsyncWebServer*
4. Move the *ESPAsyncWebServer* folder to your Arduino IDE installation libraries folder
#### Installing the **ESPAsync TCP Library**
1. Download the zip file with the [**ESPAsyncTCP Library**](https://github.com/me-no-dev/ESPAsyncTCP)
2. Unzip the folder
3. Rename your folder from ~~ESPAsyncTCP-master~~ to *ESPAsyncTCP*
4. Move the *ESPAsyncTCP* folder to your Arduino IDE installation libraries folder
5. Finally, re-open your Arduino IDE.
