# Setup Shared Yocto Cache

By default, BitBake creates the sstate-cache and downloads directories inside
the build directory. To speed up builds and reuse previously fetched sources and
build artifacts across multiple workspaces, you can configure shared locations
for these directories.

* Export `SSTATE_DIR` and `DL_DIR` variables in your shell before running the
  build commands.

```bash theme={null}
export DL_DIR="/path/to/shared/downloads"
export SSTATE_DIR="/path/to/shared/sstate"
```
