## Pointing at Shared State Cache Locations
```
If you want to know more about the Yocto Project sstate mechanism, see the

## Preserving the Download Directory
Downloading these files can take a while, particularly if your network
connection is slow.
The process downloads files into a
-"[download directory](https://www.yoctoproject.org/docs/3.1.2/ref-manual/ref-manual.html#var-DL_DIR)".
+"[download directory](https://www.yoctoproject.org/docs/3.1.4/ref-manual/ref-manual.html#var-DL_DIR)".
The `DL_DIR` variable defines the download directory.
For subsequent builds, you can preserve this directory to speed up the download
part of a build.
```
You can learn more about shared state and how it is used in the
