+
+### Overview
+We need to populate the 'github-handle' variable with the correct GitHub username for each member of the leadership team. Eventually `github-handle` will replace the `github` and `picture` variables, reducing redundancy in the project file.
+
+
+### Action Items
+- [ ] Open the file `_projects/[PROJECT FILE]` in the IDE [^1]
+- [ ] Locate the GitHub username for [INSERT MEMBER NAME] in their existing `github` variable URL (e.g.,`https://github.com/githubusername`)
+- [ ] Replace:
+```
+- name: [INSERT MEMBER NAME]
+  github-handle:
+```
+with
+```
+- name: [INSERT MEMBER NAME]
+  github-handle: [INSERT GITHUB USERNAME]
+```
+- [ ] Using docker, confirm that the appearance of the project webpage is unchanged at all screen sizes. The project webpage URL can be found below under Resources.
+
