 ## How to generate release notes
 
-1. Create an empty release notes file.
-
-    For example:
-
-    ```
-    touch 1.2.3.md
-    ```
-
-1. Run this script to find PRs which have been merged but not yet included in the latest release notes file.
+1. Run the `find_missing_prs.sh` script, passing the release version number as the only argument.
 
     ```
-    ./find_missing_prs.sh
+    ./find_missing_prs.sh 1.2.3
     ```
 
-    (See comments within the script to better understand how it works.)
+    - You can run this any time during the development cycle. If there is not yet a release branch, the script will compare `develop` to the previous release.
+    - If you haven't yet created a release notes file for this release, it will create one for you.
+    - The script will find PRs which have been merged but not yet included in the release notes file.
 
 1. Open `missing_prs.csv` to see the PRs you need to add. Incorporate them into the release notes as you see fit. Save the release notes and commit them.
 
 1. Re-run the script as needed. When more PRs are merged, they will appear in `missing_prs.csv`.
 
+## How to format the release notes content
+
+1. Group changes into sections in the following order
+
+    ```md
+    ## Security fixes
+    ## Breaking changes
+    ## New features
+    ## Groundwork
+    ## Documentation
+    ## Bug fixes
+    ## Maintenance
+    ```
+
+    You can omit sections if there are no applicable changes.
+
+1. Within the "New features" section, further categorize changes by specific features using level 3 headings.
