+# Example Project: SpecProject
+SpecProject is an example project for use with Specter. It contains examples for making an analysis pipeline, extending the UI, and creating the executable entry point.
+It also has an example CMakeLists.txt which demonstrates how to link a custom project to Specter.
+
+## Building SpecProject
+In this directory (the SpecProject directory) run the following commands:
+
+- `mkdir build`
+- `cd build && cmake .. && make -j 4`
+
+This will build the SpecProject executable and install it to the Specter/bin directory. The executable should be run from the Specter/bin directory.
