 # Technical stuff
 
+## Pre-commit
+This projects makes use of [pre-commit](https://pre-commit.com) to add some safety checks and create consistency
+in the project code. When committing changes to this project, please first [install pre-commit](https://pre-commit.com/#install),
+then activate it for this project:
+
+```bash
+pip install pre-commit
+pre-commit install
+```
+
+After installing pre-commit to your project (with `pre-commit install`), committing to the project will trigger a series
+of checks, and fixers. This process may reject your commit or make changes to your code to bring it into line with the
+project standards. For example, [Python black](https://github.com/psf/black) will be used to reformat any code. When
+changes are made by these pre-commit hooks you will need to re-add and commit those changes in order for pre-commit to
+pass.
+
+Here is some example output from pre-commit:
+
+```
+trim trailing whitespace.................................................Failed
+- hook id: trailing-whitespace

+fix end of files.........................................................Failed
+- hook id: end-of-file-fixer
+- exit code: 1

+
+This shows that two files were updated by hooks, and need to be re-added (with `git add`) before trying to commit again.

 ## Documentation
 The `README.md` file contains a table showing example badges for the different built-in colors. If you modify the
 appearance of badges, or the available colors please update the table using the following code:
