 # Github Workflows
 
-## [Push API Changes to Solo-APIs](./push-solo-apis-branch.yaml)
-This Github Action is responsible for updating [Solo-Apis](https://github.com/solo-io/solo-apis), the read-only mirror of the Gloo API. 
-When this job runs properly, it will push API changes the solo-apis repository, on a branch with the following name:
-```
-sync-apis/gloo-[GLOO_LTS_BRANCH]/gloo-[GLOO_COMMIT_TO_MIRROR]
-```
-
-From there, solo-apis automation will open a Pull Request for that branch.
-
-There are two triggers for this job, and each are explained below:
-### 1. On a Release
-Whenever Gloo Edge is released, we want to automatically update the published APIs in our read-only mirror. This action will be triggered, and after a release completes a developer needs to manually approve the PR in solo-apis.
-
-### 2. On a Manual Trigger
-We may want to test API changes in other projects, without actually merging the API changes into Gloo Edge. To do this, we push the API changes to a branch in Gloo, and then use this workflow to publish the changes to solo-apis.
-
-The arguments are:
-- `Use Workflow From`: The branch which contains the workflow code you want to execute. Often times, the default branch will work.
-- `The branch that contains the relevant API change`: The branch which contains the API changes you want to mirror
-- `The LTS branch that these API changes are targeted for`: The Gloo LTS branch which you want to merge your changes into
-
-Below are some examples for inputs to the job, if you are working on a feature branched named `feature/new-api`
-
-To test this on the default main branch:
-- Use Workflow From: `main`
-- The branch that contains the relevant API change: `feature/new-api`
-- The LTS branch that these API changes are targeted for: `main`
-
-To test this on 1.13.x branch:
-- Use Workflow From: `v1.13.x`
-- The branch that contains the relevant API change: `feature/new-api`
-- The LTS branch that these API changes are targeted for: `v1.13.x`
-
-**NOTE: After the PR opens in solo-apis, we want to avoid the chance that it merges. Please put a 'work in progress' label on the PR to prevent it from merging.**

 ## Future Work
 It would be great to add support for issue comment directives. This would mean that commenting `/sig-ci` would signal CI to run, or `/skip-ci` would auto-succeed CI.
