 To install PXF, first make sure that the user has sufficient permissions in the `$GPHOME` and `$PXF_HOME` directories to perform the installation. It's recommended to change ownership to match the installing user. For example, when installing PXF as user `gpadmin` under `/usr/local/cloudberrydb`:
 
 ```bash
-export GPHOME=/usr/local/cloudberrydb
+export GPHOME=/usr/local/cloudberry-db
 export PXF_HOME=/usr/local/pxf
 export PXF_BASE=${HOME}/pxf-base
 chown -R gpadmin:gpadmin "${GPHOME}" "${PXF_HOME}"
-make -C ~/workspace/pxf install
+make -C ~/workspace/cloudberry-db install
 ```
 
 NOTE: if `PXF_BASE` is not set, it will default to `PXF_HOME`, and server configurations, libraries or other configurations, might get deleted after a PXF re-install.
