 3. For key comments containing such URLs, a Git config setting is written that uses [`url.<base>.insteadof`](https://git-scm.com/docs/git-config#Documentation/git-config.txt-urlltbasegtinsteadOf). It will redirect `git` requests to URLs starting with either `https://github.com/owner/repo` or `git@github.com:owner/repo` to a fake hostname/URL like `git@...some.hash...:owner/repo`.
 4. An SSH configuration section is generated that applies to the fake hostname. It will map the SSH connection back to `github.com`, while at the same time pointing SSH to a file containing the appropriate key's public part. That will make SSH use the right key when connecting to GitHub.com.

-## Action Inputs
-
-The following inputs can be used to control the action's behavior:
-
-* `ssh-private-key`: Required. Use this to provide the key(s) to load as GitHub Actions secrets.
-* `ssh-auth-sock`: Can be used to control where the SSH agent socket will be placed. Ultimately affects the `$SSH_AUTH_SOCK` environment variable.
-* `log-public-key`: Set this to `false` if you want to suppress logging of _public_ key information. To simplify debugging and since it contains public key information only, this is turned on by default.
-* `ssh-agent-cmd`: Optional. Use this to specify a custom location for the `ssh-agent` binary.
-* `ssh-add-cmd`: Optional. Use this to specify a custom location for the `ssh-add` binary.
-* `git-cmd`: Optional. Use this to specify a custom location for the `git` binary.
-
 ## Exported variables
-
 The action exports the `SSH_AUTH_SOCK` and `SSH_AGENT_PID` environment variables through the Github Actions core module.
 The `$SSH_AUTH_SOCK` is used by several applications like git or rsync to connect to the SSH authentication agent.
 The `$SSH_AGENT_PID` contains the process id of the agent. This is used to kill the agent in post job action.

-### Using Multiple Deploy Keys Inside Docker Builds
-
-When you pass the SSH agent socket to the Docker build environment _and_ want to use multiple GitHub deploy keys, you need to copy the Git and SSH configuration files to the build environment as well. This is necessary _in addition to_ forwarding the SSH agent socket into the build process. The config files are required so that Git can pick the right one from your deployment keys.
-
-This requires an additional step in the workflow file **after** the `ssh-agent` step and **before** the Docker build step.  You also need two additional lines in the `Dockerfile` to actually copy the configs.
-
-The following example will: 
-* collect the necessary Git and SSH configuration files in a directory that must be part of the Docker build context so that... 
-* ... the files can be copied into the Docker image (or an intermediate build stage).
-
-Workflow:
-
-```yml
-      - name: ssh-agent setup
-        ...
-
-      - name: Collect Git and SSH config files in a directory that is part of the Docker build context
-        run: |
-          mkdir root-config
-          cp -r ~/.gitconfig  ~/.ssh root-config/
-  
-      - name: Docker build 
-        # build-push-action | docker [compose] build | etc.
-        ...
-```
-
-Dockerfile:
-
-```Dockerfile
-# Copy the two files in place and fix different path/locations inside the Docker image
-COPY root-config /root/
-RUN sed 's|/home/runner|/root|g' -i.bak /root/.ssh/config
-```
-
-Keep in mind that the resulting Docker image now might contain these customized Git and SSH configuration files! Your private SSH keys are never written to files anywhere, just loaded into the SSH agent and forwarded into the container. The config files might, however, give away details about your build or development process and contain the names and URLs of your (private) repositories. You might want to use a multi-staged build to make sure these files do not end up in the final image.
-
-If you still get the error message: `fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.`, you most likely forgot one of the steps above.
