+   Renovate is a service similar to GitHub Dependabot, but with

+## NAME
+skopeo\-generate-sigstore-key - Generate a sigstore public/private key pair.
+
+## SYNOPSIS
+**skopeo generate-sigstore-key** [*options*] **--output-prefix** _prefix_
+
+## DESCRIPTION
+
+Generates a public/private key pair suitable for creating sigstore image signatures.
+The private key is encrypted with a passphrase;
+if one is not provided using an option, this command prompts for it interactively.
+
+The private key is written to _prefix_**.private** .
+The private key is written to _prefix_**.pub** .
+
+## OPTIONS
+
+**--help**, **-h**
+
+Print usage statement
+
+**--output-prefix** _prefix_
+
+Mandatory.
+Path prefix for the output keys (_prefix_**.private** and _prefix_**.pub**).
+
+**--passphrase-file** _path_
+
+The passphare to use to encrypt the private key.
+Only the first line will be read.
+A passphrase stored in a file is of questionable security if other users can read this file.
+Do not use this option if at all avoidable.

-We also require that contributors sign their commits using git commit -s or git commit --signoff to certify they either authored the work themselves

+Additionally, the pull request pipeline requires the following steps to be performed before

+### Code Sign-Off
+
+We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
+to certify they either authored the work themselves or otherwise have permission to use it in this project.
+
+A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
+

+as well as to make sure that you can attest to the rules listed.
+Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+    "go.lintTool": "golangci-lint",
+    "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run ./...
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+
+This can be done for the entire repo:
+
+```shell
+> go generate ./...
+```

+## Security
+
+Microsoft takes the security of our software products and services seriously, which includes all source code repositories managed through our GitHub organizations, which include [Microsoft](https://github.com/Microsoft), [Azure](https://github.com/Azure), [DotNet](https://github.com/dotnet), [AspNet](https://github.com/aspnet), [Xamarin](https://github.com/xamarin), and [our GitHub organizations](https://opensource.microsoft.com/).
+
+If you believe you have found a security vulnerability in any Microsoft-owned repository that meets [Microsoft's definition of a security vulnerability](https://aka.ms/opensource/security/definition), please report it to us as described below.
+
+## Reporting Security Issues
+
+**Please do not report security vulnerabilities through public GitHub issues.**
+
+Instead, please report them to the Microsoft Security Response Center (MSRC) at [https://msrc.microsoft.com/create-report](https://aka.ms/opensource/security/create-report).
+
+If you prefer to submit without logging in, send email to [secure@microsoft.com](mailto:secure@microsoft.com).  If possible, encrypt your message with our PGP key; please download it from the [Microsoft Security Response Center PGP Key page](https://aka.ms/opensource/security/pgpkey).
+
+You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Additional information can be found at [microsoft.com/msrc](https://aka.ms/opensource/security/msrc). 
+
+Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
+
+  * Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
+  * Full paths of source file(s) related to the manifestation of the issue
+  * The location of the affected source code (tag/branch/commit or direct URL)
+  * Any special configuration required to reproduce the issue
+  * Step-by-step instructions to reproduce the issue
+  * Proof-of-concept or exploit code (if possible)
+  * Impact of the issue, including how an attacker might exploit the issue
+
+This information will help us triage your report more quickly.
+
+If you are reporting for a bug bounty, more complete reports can contribute to a higher bounty award. Please visit our [Microsoft Bug Bounty Program](https://aka.ms/opensource/security/bounty) page for more details about our active programs.
