 ## Directory structure
 Top level directory structure:
 - `typ`: Input files.
+- `res`: Resource files used by tests.
 - `ref`: Reference images which the output is compared with to determine whether
          a test passed or failed.
 - `png`: PNG files produced by tests.
 - `pdf`: PDF files produced by tests.
-- `res`: Resource files used by tests.
 
 ## Running the tests
+Running the integration tests (the tests in this directory).
 ```bash
-# Run all tests
-cargo test
-
-# Run unit tests
-cargo test --lib
-
-# Run integration tests (the tests in this directory)
 cargo test --test typeset
+```
 
-# Run all tests whose names contain the word `filter`
+Running all tests whose names contain the word `filter`.
+```bash
 cargo test --test typeset filter
 ```
 
+To make the integration tests go faster they don't generate PDFs by default.
+Pass the `--pdf` flag to generate those. Mind that PDFs are not tested
+automatically at the moment, so you should always check the output manually when
+making changes.
+```bash
+cargo test --test typeset -- --pdf
+```

+When you use the approve buttom from the Test Helper (see the `tools` folder)
+this happens automatically if you have `oxipng` installed.
 ```bash
