-Subject: PATCH EncodeAlphaInternal: clear result->bw on error
-
-This avoids a double free should the function fail prior to
-VP8BitWriterInit() and a previous trial result's buffer carried over.
-Previously in ApplyFiltersAndEncode() trial.bw (with a previous
-iteration's buffer) would be freed, followed by best.bw pointing to the
-same buffer.
-
-Since:
-187d379d add a fallback to ALPHA_NO_COMPRESSION
-
-In addition, check the return value of VP8BitWriterInit() in this
-function.
-
-Bug: webp:603
-Change-Id: Ic258381ee26c8c16bc211d157c8153831c8c6910

 All submissions, including submissions by project members, require review. We
 use a Gerrit(https://www.gerritcodereview.com) instance hosted at
-https://chromium-review.googlesource.com for this purpose. See the
+https://chromium-review.googlesource.com for this purpose.
+
+## Sending patches
+
+The basic git workflow for modifying libwebp code and sending for review is:
+
+1.  Get the latest version of the repository locally:
+
+    ```sh
+    git clone https://chromium.googlesource.com/webm/libwebp && cd libwebp
+    ```
+
+2.  Copy the commit-msg script into ./git/hooks (this will add an ID to all of
+    your commits):
+
+    ```sh
+    curl -Lo .git/hooks/commit-msg https://chromium-review.googlesource.com/tools/hooks/commit-msg && chmod u+x .git/hooks/commit-msg
+    ```
+
+3.  Modify the local copy of libwebp. Make sure the code
+    builds successfully(https://chromium.googlesource.com/webm/libwebp/+/HEAD/doc/building.md#cmake).
+
+4.  Choose a short and representative commit message:
+
+    ```sh
+    git commit -a -m "Set commit message here"
+    ```
+
+5.  Send the patch for review:
+
+    ```sh
+    git push https://chromium-review.googlesource.com/webm/libwebp HEAD:refs/for/main
+    ```
+
+    Go to https://chromium-review.googlesource.com to view your patch and
+    request a review from the maintainers.
+
+See the
 WebM Project page(https://www.webmproject.org/code/contribute/submitting-patches/)
 for additional details.
 
+## Code Style
+
+The C code style is based on the
+Google C++ Style Guide(https://google.github.io/styleguide/cppguide.html) and
+`clang-format --style=Google`, though this project doesn't use the tool to
+enforce the formatting.
+
+CMake files are formatted with
+cmake-format(https://cmake-format.readthedocs.io/en/latest/). `cmake-format
+-i` can be used to format individual files, it will use the settings from
+`.cmake-format.py`.
