@ -176,6 +176,12 @@ Going into `build` directory, you will find additional possibilities:
You can build the zstd binary via buck by executing: `buck build programs:zstd` from the root of the repo.
The output binary will be in `buck-out/gen/programs/`.
## Testing
You can run quick local smoke tests by executing the `playTest.sh` script from the `src/tests` directory.
Two env variables `$ZSTD_BIN` and `$DATAGEN_BIN` are needed for the test script to locate the zstd and datagen binary.
For information on CI testing, please refer to TESTING.md
## Status
Zstandard is currently deployed within Facebook. It is used continuously to compress large amounts of data in multiple formats and use cases.
