 ### Running kvssink Samples
-The SDK comes with two programatic GStreamer samples: `kvssink_gstreamer_sample` and `kvssink_intermittent_sample`. For more use cases, see the CLI pipeline examples at [Example: Kinesis Video Streams Producer SDK GStreamer Plugin](https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/examples-gstreamer-plugin.html).

-The programtic samples require for the AWS region to be set with the `AWS_DEFAULT_REGION` environment variable. For example:

+The programmatic samples require the AWS region to be set with the `AWS_DEFAULT_REGION` environment variable. For example:
+```bash
 export AWS_DEFAULT_REGION=us-west-2
 ```
 
 After building the SDK, loading kvssink into the GStreamer plugin path, and setting a region, the sample executables, which are located in the `build` directory, can be run.
 
 #### kvssink Intermittent Sample
 Usage:
-```
+```bash
 ./kvssink_intermittent_sample <stream-name (optional)> <testsrc or devicesrc (optional)>
 ```
 Setting the source to `testsrc` will use [videotestsrc](https://gstreamer.freedesktop.org/documentation/videotestsrc/?gi-language=c) and to `devicesrc` will use [autovideosrc](https://gstreamer.freedesktop.org/documentation/autodetect/autovideosrc.html?gi-language=c). By default, kvssink uses "DEFAULT_STREAM" as the stream name, and the sample uses videotestsrc as the source. If a stream with the provided or default name does not exist, the stream will automatically be created.
 
-The intermittent kvssink sample will stream video for 20 seconds, then pause for 40 seconds, and repeat until an inturupt signal is received. To manually adjust the streaming/paused intervals, you can change the `KVS_INTERMITTENT_PLAYING_INTERVAL_SECONDS` and `KVS_INTERMITTENT_PAUSED_INTERVAL_SECONDS` values in the *kvssink_intermittent_sample.cpp* file.
