You can install downloaded extensions by copying them into `extensions`. For example,
```
cp -R extensions-tmp/druid-example-extension extensions/druid-example-extension
```
You only have to install the extension once. Then, add `"druid-example-extension"` to
`druid.extensions.loadList` in common.runtime.properties to instruct Druid to load the extension. If
you used *pull-deps*, then once an extension is installed, you can remove the `extensions-tmp` and
`hadoop-dependencies-tmp` directories that it created.
`druid.extensions.loadList` in common.runtime.properties to instruct Druid to load the extension.
