+## Categories
+
+The list of categories available on crates.io is stored in
+`src/categories.toml`. To propose adding, removing, or changing a category,
+send a pull request making the appropriate change to that file as noted in the
+comment at the top of the file. Please add a description that will help others
+to know what crates are in that category.
+
+For new categories, it's helpful to note in your PR description examples of
+crates that would fit in that category, and describe what distinguishes the new
+category from existing categories.
+
+After your PR is accepted, the next time that crates.io is deployed the
+categories will be synced from this file.
