-# Updating Blimp Fonts
-
-1.  Clone the git-repositories listed in
-    `//third_party/blimp_fonts/README.chromium`, and roll forward to the commit
-    you want.
-1.  Copy the necessary files to `//third_party/blimp_fonts`.
-1.  Verify that the `LICENSE` file is still up to date and lists all relevant
-    licenses and which fonts use which license.
-1.  Update the `//third_party/blimp_fonts:fonts` target to include all the
-    current fonts and their license files.
-1.  Update the engine dependencies using
-    `//blimp/tools/generate-engine-manifest.py`. This step is documented in
-    `//blimp/docs/container.md`.
-1.  Run the `upload_to_google_storage.py` (from depot_tools) script to upload
-    the files. To do this, execute:
-
-    ```bash
-    find ./third_party/blimp_fonts \
-        -regex '^.*.\(ttf\|otf\)$' -type f -print0 | \
-        upload_to_google_storage.py --use_null_terminator -b chromium-fonts -
-    ```
-
-    If the set of fonts includes more than `.ttf` or `.otf` files, you must
-    update the regular expression to include such fonts.
-1.  Verify that `//third_party/blimp_fonts/.gitignore` lists the correct files
-    to ignore.
-1.  Add all the `.sha1` files to the chromium src repository, by executing the
-    following command:
-
-    ```bash
-    git add ./third_party/blimp_fonts/*.sha1
-    ```
-
-1.  Commit and upload the change for review:
-
-    ```bash
-    git commit
-    git cl upload
-    ```
