# Built from source

Before you proceed with installing Singularity, make sure you have [Go 1.20 or higher](https://golang.org/dl/) installed on your system.

## Setting Up Go

To get Go up and running, follow these steps:

1. **Download and Extract Go Binaries**:

       >> ~/.bashrc && source ~/.bashrc
