-# ${REPO_NAME}
+# Audio Commands using DTMF
 
-${REPO_DESCRIPTION}
+This is a simple example of how to use DTMF elements of GStreamer with ergonomic Rust code.
+
+## Installation
+
+You will need to install the following dependencies from homebrew:
+
+```bash
+brew install gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-libav
+```
+
+Edit the gst-plugins-bad formula to add the following line:
+
+```ruby
+depends_on "spandsp"
+```
+
+Set the following environment variables:
+
+```bash
+export HOMEBREW_NO_INSTALL_FROM_API=1
+```
+
+Then reinstall the formula from source:
+
+```bash
+brew reinstall --build-from-source gst-plugins-bad
+```
