-## Memory Leak Detection
-
-To run the leak detector against the FFI-exposed portion of
-libsector_builder_ffi.a, simply run the FFI example with leak detection enabled.
-On a Linux machine, you can run the following command:
-
-```shell
-RUSTFLAGS="-Z sanitizer=leak" cargo run --release --package filecoin-proofs --example ffi --target x86_64-unknown-linux-gnu
-```
-
-If using mac OS, you'll have to run the leak detection from within a Docker
-container. After installing Docker, run the following commands to build and run
-the proper Docker image and then the leak detector itself:
-
-```shell
-docker build -t foo -f ./Dockerfile-ci . && \
-  docker run \
-    -it \
-    -e RUSTFLAGS="-Z sanitizer=leak" \
-    --privileged \
-    -w /mnt/crate \
-    -v `pwd`:/mnt/crate -v $(TMP=$(mktemp -d) && mv ${TMP} /tmp/ && echo /tmp${TMP}):/mnt/crate/target \

 ## Parameter File Location
 
 Filecoin proof parameter files are expected to be located in `/var/tmp/filecoin-proof-parameters`.  If they are located in an alternate location, you can point the system to that location using an environment variable
