+# Installation
+HOWTO Install. Development is currently done using Debian stable
+(Bullseye/11), which uses Python 3.9. Perhaps do something like this, or
+set up a Python virtual environment.
+
+```
+sudo apt update
+sudo apt install python3-pip
+pip install --user --upgrade pip
+pip install --user --upgrade -r requirements.txt
+```
+
+
+# Usage
+HOWTO USE.
+The first step is to record a sample. This is similar to just doing an
+audio recording. The next step is to process that file, then visualize,
+then categorize. Along these lines...
+
+```
+./witgit-rec --device [hardware] [filename]    # Record
+./witgit-proc [filename]                       # Process
+./witgit-view [filename]                       # View Plot
+./witgit-wut [filename]                        # Categorize
+```
+
 
 # Upstream
 The code will be built using bits from other free software / open source
