 To test with bpcat:
 
 1. Open two terminal windows and have them both visible. The test runs `bpcat` as a receiver in one window and a sender in the other.
-2. In both terminals run: `cd "${BPLIB_HOME}/bplib-build-matrix-Debug/POSIX/app"`
+2. In both terminals run:
+   `cd <same chosen working directory>/bplib-build-matrix-<Debug or Release>-POSIX/app`
 3. The files `bpcat` and `Makefile` should be in the current directory.
 4. In one terminal, create the `storage` folder required for the test.
  `mkdir storage`
 5. In the same terminal, run the receiver with:
  `./bpcat -l ipn://101.1 -r ipn://201.1 |& tee recv.log`
-6. In the other terminal, run the sender with: `./bpcat -l ipn://201.1 -r ipn://101.1 -i Makefile |& tee send.log`
+6. In the other terminal, run the sender with:
+ `./bpcat -l ipn://201.1 -r ipn://101.1 -i Makefile |& tee send.log`
 7. For a successful test the contents of the Makefile appear in the receiver terminal.
 8. Terminate `bpcat` in both terminal windows by pressing `CTRL-C` in each window.
