+# Integrate Scripts
+
+A collection of scripts used to integrate the StableHLO repository into the
+rest of the OpenXLA repos. These scripts are run ~2x/wk by a StableHLO oncall
+rotation at Google to ensure new changes can propagate to the rest of the
+ecosystem in a reasonable amount of time.
+
+## Integrate Process
+
+### Bump LLVM Revision
+
+First we bump LLVM to match that of XLA, and apply any patches the the XLA
+LLVM integrate had to apply to StableHLO to build LLVM:
+
+```
+$ ./build_tools/integrate/llvm_bump_revision.sh
+```
+
+### Integarte into OpenXLA Repositories
+
+The StableHLO oncall then integrates the change into the google monorepo, which
+propagates the new StableHLO features to XLA, Shardy, JAX, TF, etc, including
+any changes or patches that were needed to build these projects with the new
+feature.
+
+_Note: this is the only step that must be carried out by a Google team member._
+
+### Tag the integrated StableHLO commit and bump StableHLO version numbers
+
+This step takes care of a few things:
+1. Add a tag for the integrated StableHLO version
+2. Bump the patch version in [Version.h](https://github.com/openxla/stablehlo/tree/main/stablehlo/dialect/Version.h#L41)
+3. Bump the 4w and 12w forward compatibility requirement versions in
+   [Version.cpp](https://github.com/openxla/stablehlo/blob/main/stablehlo/dialect/Version.cpp#L75)
+
+```
+Usage: ./build_tools/integrate/stablehlo_tag_and_bump_version.sh [-t <COMMIT_TO_TAG>]
+   -t  Specify a commit to tag, must be an integrated StableHLO commit
+       available on https://github.com/search?q=repo%3Aopenxla%2Fxla+integrate+stablehlo&type=commits
+       If not specifed, will only bump the 4w and 12w versions.
+
+$ ./build_tools/integrate/stablehlo_tag_and_bump_version.sh -t 37487a8e
+```
