## Validating Your metainfo.xml File

To validate your `metainfo.xml` file, install `appstream`, then run `appstreamcli validate NAME.metainfo.xml`.
Errors and warnings should be corrected to the best of your ability. In rare cases, errors are fine to have, such as `E: com.github.neohtop:6: metainfo-invalid-icon-type local`.
`infos` can be ignored or corrected at your discretion.

Here is an example of the output of running `appstreamcli validate` on a proper metainfo.xml file:

```bash
appstreamcli validate games/minecraft-java/com.mojang.Minecraft.metainfo.xml
I: com.mojang.Minecraft:50: nonstandard-gnome-extension metadata
I: com.mojang.Minecraft:~: developer-info-missing
```
