# Install GCC Man Pages on Debian 10 Buster

The Man Pages for GCC compiler are not included by default on Debian 10 Buster and must be added by installing the Backport package named ***gcc-doc***. To complete this task, I recommend you should add the Backports sources with options *main contrib* to your source files **/etc/apt/sources.list.d/** directory on a file named buster-backports.list. You can do this with this command:

```bash
echo deb http://deb.debian.org/debian buster-backports main contrib | sudo tee /etc/apt/sources.list.d/buster-backports.list
```

After this, run:

```bash
sudo apt update
```

And:

```bash
sudo apt install gcc gcc-doc
```

Now try running this to corroborate proper installation of GCC's man pages.

```bash
man gcc
```

**Note:** You could also add the *non-free* option to your Backports source if you are interested in other unrelated non-free software later on, but it is not required for installing *gcc-doc*.
