 Tying the API endpoint info to the credentials allows us to use the same ```garm``` installation with both [github.com](https://github.com) and private deployments. All you have to do is to add the needed endpoint info (see bellow).

-Garm uses a [Personal Access Token (PAT)](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) to create runner registration tokens, list current self hosted runners and potentially remove them if they become orphaned (the VM was manually removed on the provider).
+GARM has the option to use both [Personal Access Tokens (PAT)](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) or a [GitHub App](https://docs.github.com/en/apps/creating-github-apps/registering-a-github-app/registering-a-github-app).

-From the list of scopes, you will need to select:
+
+If you'll use a PAT, you'll have to grant access for the following scopes:

 * ```public_repo``` - for access to a repository
 * ```repo``` - for access to a private repository
 * ```admin:org``` - if you plan on using this with an organization to which you have access
 * ```manage_runners:enterprise``` - if you plan to use garm at the enterprise level
+* ```admin:repo_hook``` - if you want to allow GARM to install webhooks on repositories (optional)
+* ```admin:org_hook``` - if you want to allow GARM to install webhooks on organizations (optional)

-The resulting token must be configured in the ```[[github]]``` section of the config. Sample as follows:

+* **Organization permissions**:
+  * ```Self-hosted runners: Read & write```
+  * ```Webhooks: Read & write```
+
+**Note** :warning:: Github Apps are not available at the enterprise level.

+
+[![GoDoc](https://godoc.org/github.com/bradleyfalzon/ghinstallation?status.svg)](https://godoc.org/github.com/bradleyfalzon/ghinstallation/v2)
+
+`ghinstallation` provides `Transport`, which implements `http.RoundTripper` to
+provide authentication as an installation for GitHub Apps.
+
+This library is designed to provide automatic authentication for
+https://github.com/google/go-github or your own HTTP client.
+
+See
+https://developer.github.com/apps/building-integrations/setting-up-and-registering-github-apps/about-authentication-options-for-github-apps/
+
+# Installation
+
+Get the package:
+
+```bash
+GO111MODULE=on go get -u github.com/bradleyfalzon/ghinstallation/v2
+```
+
+# GitHub Example
+
+```go
+import "github.com/bradleyfalzon/ghinstallation/v2"
+
+func main() {
+    // Shared transport to reuse TCP connections.
+    tr := http.DefaultTransport
+
+    // Wrap the shared transport for use with the app ID 1 authenticating with installation ID 99.
+    itr, err := ghinstallation.NewKeyFromFile(tr, 1, 99, "2016-10-19.private-key.pem")
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    // Use installation transport with github.com/google/go-github
+    client := github.NewClient(&http.Client{Transport: itr})
+}
+```
+
+You can also use [`New()`](https://pkg.go.dev/github.com/bradleyfalzon/ghinstallation/v2#New) to load a key directly from a `[]byte`.
+
+# GitHub Enterprise Example
+
+For clients using GitHub Enterprise, set the base URL as follows:
+
+```go
+import "github.com/bradleyfalzon/ghinstallation/v2"
+
+const GitHubEnterpriseURL = "https://github.example.com/api/v3"
+
+func main() {
+    // Shared transport to reuse TCP connections.
+    tr := http.DefaultTransport
+
+    // Wrap the shared transport for use with the app ID 1 authenticating with installation ID 99.
+    itr, err := ghinstallation.NewKeyFromFile(tr, 1, 99, "2016-10-19.private-key.pem")
+    if err != nil {
+        log.Fatal(err)
+    }
+    itr.BaseURL = GitHubEnterpriseURL
+
+    // Use installation transport with github.com/google/go-github
+    client := github.NewEnterpriseClient(GitHubEnterpriseURL, GitHubEnterpriseURL, &http.Client{Transport: itr})
+}
+```
+
+## What is app ID and installation ID
+
+`app ID` is the GitHub App ID. \
+You can check as following : \
+Settings > Developer > settings > GitHub App > About item
+
+`installation ID` is a part of WebHook request. \
+You can get the number to check the request. \
+Settings > Developer > settings > GitHub Apps > Advanced > Payload in Request
+tab
+
+```
+WebHook request
+...
+  "installation": {
+    "id": `installation ID`
+  }
+```
+
+# Customizing signing behavior
+
+Users can customize signing behavior by passing in a
+[Signer](https://pkg.go.dev/github.com/bradleyfalzon/ghinstallation/v2#Signer)
+implementation when creating an
+[AppsTransport](https://pkg.go.dev/github.com/bradleyfalzon/ghinstallation/v2#AppsTransport).
+For example, this can be used to create tokens backed by keys in a KMS system.
+
+```go
+signer := &myCustomSigner{
+  key: "https://url/to/key/vault",
+}
+atr := NewAppsTransportWithOptions(http.DefaultTransport, 1, WithSigner(signer))
+tr := NewFromAppsTransport(atr, 99)
+```

+## Migration Guide (v4.0.0)
+
+Starting from [v4.0.0](https://github.com/golang-jwt/jwt/releases/tag/v4.0.0), the import path will be:
+
+    "github.com/golang-jwt/jwt/v4"
+
+The `/v4` version will be backwards compatible with existing `v3.x.y` tags in this repo, as well as 
+`github.com/dgrijalva/jwt-go`. For most users this should be a drop-in replacement, if you're having 
+troubles migrating, please open an issue.
+
+You can replace all occurrences of `github.com/dgrijalva/jwt-go` or `github.com/golang-jwt/jwt` with `github.com/golang-jwt/jwt/v4`, either manually or by using tools such as `sed` or `gofmt`.
+
+And then you'd typically run:
+
+```
+go get github.com/golang-jwt/jwt/v4
+go mod tidy
+```
+
+## Older releases (before v3.2.0)
+
+The original migration guide for older releases can be found at https://github.com/dgrijalva/jwt-go/blob/master/MIGRATION_GUIDE.md.

+[![build](https://github.com/golang-jwt/jwt/actions/workflows/build.yml/badge.svg)](https://github.com/golang-jwt/jwt/actions/workflows/build.yml)
+[![Go Reference](https://pkg.go.dev/badge/github.com/golang-jwt/jwt/v4.svg)](https://pkg.go.dev/github.com/golang-jwt/jwt/v4)
+
+A [go](http://www.golang.org) (or 'golang' for search engine friendliness) implementation of [JSON Web Tokens](https://datatracker.ietf.org/doc/html/rfc7519).
+
+Starting with [v4.0.0](https://github.com/golang-jwt/jwt/releases/tag/v4.0.0) this project adds Go module support, but maintains backwards compatibility with older `v3.x.y` tags and upstream `github.com/dgrijalva/jwt-go`.
+See the [`MIGRATION_GUIDE.md`](./MIGRATION_GUIDE.md) for more information.
+
+> After the original author of the library suggested migrating the maintenance of `jwt-go`, a dedicated team of open source maintainers decided to clone the existing library into this repository. See [dgrijalva/jwt-go#462](https://github.com/dgrijalva/jwt-go/issues/462) for a detailed discussion on this topic.
+
+
+**SECURITY NOTICE:** Some older versions of Go have a security issue in the crypto/elliptic. Recommendation is to upgrade to at least 1.15 See issue [dgrijalva/jwt-go#216](https://github.com/dgrijalva/jwt-go/issues/216) for more detail.
+
+**SECURITY NOTICE:** It's important that you [validate the `alg` presented is what you expect](https://auth0.com/blog/critical-vulnerabilities-in-json-web-token-libraries/). This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage.  See the examples provided.
+
+### Supported Go versions
+
+Our support of Go versions is aligned with Go's [version release policy](https://golang.org/doc/devel/release#policy).
+So we will support a major version of Go until there are two newer major releases.
+We no longer support building jwt-go with unsupported Go versions, as these contain security vulnerabilities
+which will not be fixed.
+
+## What the heck is a JWT?
+
+JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
+
+In short, it's a signed JSON object that does something useful (for example, authentication).  It's commonly used for `Bearer` tokens in Oauth 2.  A token is made of three parts, separated by `.`'s.  The first two parts are JSON objects, that have been [base64url](https://datatracker.ietf.org/doc/html/rfc4648) encoded.  The last part is the signature, encoded the same way.
+
+The first part is called the header.  It contains the necessary information for verifying the last part, the signature.  For example, which encryption method was used for signing and what key was used.
+
+The part in the middle is the interesting bit.  It's called the Claims and contains the actual stuff you care about.  Refer to [RFC 7519](https://datatracker.ietf.org/doc/html/rfc7519) for information about reserved keys and the proper way to add your own.
+
+## What's in the box?
+
+This library supports the parsing and verification as well as the generation and signing of JWTs.  Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
+
+## Installation Guidelines
+
+1. To install the jwt package, you first need to have [Go](https://go.dev/doc/install) installed, then you can use the command below to add `jwt-go` as a dependency in your Go program.
+
+```sh
+go get -u github.com/golang-jwt/jwt/v4
+```
+
+2. Import it in your code:
+
+```go
+import "github.com/golang-jwt/jwt/v4"
+```
+
+## Examples
+
+See [the project documentation](https://pkg.go.dev/github.com/golang-jwt/jwt/v4) for examples of usage:
+
+* [Simple example of parsing and validating a token](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#example-Parse-Hmac)
+* [Simple example of building and signing a token](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#example-New-Hmac)
+* [Directory of Examples](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#pkg-examples)
+
+## Extensions
+
+This library publishes all the necessary components for adding your own signing methods or key functions.  Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod` or provide a `jwt.Keyfunc`.
+
+A common use case would be integrating with different 3rd party signature providers, like key management services from various cloud providers or Hardware Security Modules (HSMs) or to implement additional standards.
+
+| Extension | Purpose                                                                                                  | Repo                                       |
+| --------- | -------------------------------------------------------------------------------------------------------- | ------------------------------------------ |
+| GCP       | Integrates with multiple Google Cloud Platform signing tools (AppEngine, IAM API, Cloud KMS)             | https://github.com/someone1/gcp-jwt-go     |
+| AWS       | Integrates with AWS Key Management Service, KMS                                                          | https://github.com/matelang/jwt-go-aws-kms |
+| JWKS      | Provides support for JWKS ([RFC 7517](https://datatracker.ietf.org/doc/html/rfc7517)) as a `jwt.Keyfunc` | https://github.com/MicahParks/keyfunc       |
+
+*Disclaimer*: Unless otherwise specified, these integrations are maintained by third parties and should not be considered as a primary offer by any of the mentioned cloud providers
+
+## Compliance
+
+This library was last reviewed to comply with [RFC 7519](https://datatracker.ietf.org/doc/html/rfc7519) dated May 2015 with a few notable differences:
+
+* In order to protect against accidental use of [Unsecured JWTs](https://datatracker.ietf.org/doc/html/rfc7519#section-6), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
+
+## Project Status & Versioning
+
+This library is considered production ready.  Feedback and feature requests are appreciated.  The API should be considered stable.  There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
+
+This project uses [Semantic Versioning 2.0.0](http://semver.org).  Accepted pull requests will land on `main`.  Periodically, versions will be tagged from `main`.  You can find all the releases on [the project releases page](https://github.com/golang-jwt/jwt/releases).
+
+**BREAKING CHANGES:*** 
+A full list of breaking changes is available in `VERSION_HISTORY.md`.  See `MIGRATION_GUIDE.md` for more information on updating your code.
+
+## Usage Tips
+
+### Signing vs Encryption
+
+A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data:
+
+* The author of the token was in the possession of the signing secret
+* The data has not been modified since it was signed
+
+It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. The companion project https://github.com/golang-jwt/jwe aims at a (very) experimental implementation of the JWE standard.
+
+### Choosing a Signing Method
+
+There are several signing methods available, and you should probably take the time to learn about the various options before choosing one.  The principal design decision is most likely going to be symmetric vs asymmetric.
+
+Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation.
+
+Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
+
+### Signing Methods and Key Types
+
+Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones:
+
+* The [HMAC signing method](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation
+* The [RSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation
+* The [ECDSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation
+* The [EdDSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#SigningMethodEd25519) (`Ed25519`) expect `ed25519.PrivateKey` for signing and `ed25519.PublicKey` for validation
+
+### JWT and OAuth
+
+It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
+
+Without going too far down the rabbit hole, here's a description of the interaction of these technologies:
+
+* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
+* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
+* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.
+
+### Troubleshooting
+
+This library uses descriptive error messages whenever possible. If you are not getting the expected result, have a look at the errors. The most common place people get stuck is providing the correct type of key to the parser. See the above section on signing methods and key types.

+## `jwt-go` Version History
+
+#### 4.0.0
+
+* Introduces support for Go modules. The `v4` version will be backwards compatible with `v3.x.y`.
+
+#### 3.2.2
+
+* Starting from this release, we are adopting the policy to support the most 2 recent versions of Go currently available. By the time of this release, this is Go 1.15 and 1.16 ([#28](https://github.com/golang-jwt/jwt/pull/28)).
+* Fixed a potential issue that could occur when the verification of `exp`, `iat` or `nbf` was not required and contained invalid contents, i.e. non-numeric/date. Thanks for @thaJeztah for making us aware of that and @giorgos-f3 for originally reporting it to the formtech fork ([#40](https://github.com/golang-jwt/jwt/pull/40)).
+* Added support for EdDSA / ED25519 ([#36](https://github.com/golang-jwt/jwt/pull/36)).
+* Optimized allocations ([#33](https://github.com/golang-jwt/jwt/pull/33)).
+
+#### 3.2.1
+
+* **Import Path Change**: See MIGRATION_GUIDE.md for tips on updating your code
+	* Changed the import path from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt`
+* Fixed type confusing issue between `string` and `[]string` in `VerifyAudience` ([#12](https://github.com/golang-jwt/jwt/pull/12)). This fixes CVE-2020-26160 
+
+#### 3.2.0
+
+* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation
+* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate
+* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior. Initial set include `WithClaims` and `WithParser`. Existing usage of this function will continue to work as before.
+* Deprecated `ParseFromRequestWithClaims` to simplify API in the future.
+
+#### 3.1.0
+
+* Improvements to `jwt` command line tool
+* Added `SkipClaimsValidation` option to `Parser`
+* Documentation updates
+
+#### 3.0.0
+
+* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
+	* Dropped support for `[]byte` keys when using RSA signing methods.  This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
+	* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
+	* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`.  The default value is type `MapClaims`, which is an alias to `map[string]interface{}`.  This makes it possible to use a custom type when decoding claims.
+* Other Additions and Changes
+	* Added `Claims` interface type to allow users to decode the claims into a custom type
+	* Added `ParseWithClaims`, which takes a third argument of type `Claims`.  Use this function instead of `Parse` if you have a custom type you'd like to decode into.
+	* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
+	* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
+	* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests.  Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
+	* Added several new, more specific, validation errors to error type bitmask
+	* Moved examples from README to executable example files
+	* Signing method registry is now thread safe
+	* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)
+
+#### 2.7.0
+
+This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
+
+* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
+* Error text for expired tokens includes how long it's been expired
+* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
+* Documentation updates
+
+#### 2.6.0
+
+* Exposed inner error within ValidationError
+* Fixed validation errors when using UseJSONNumber flag
+* Added several unit tests
+
+#### 2.5.0
+
+* Added support for signing method none.  You shouldn't use this.  The API tries to make this clear.
+* Updated/fixed some documentation
+* Added more helpful error message when trying to parse tokens that begin with `BEARER `
+
+#### 2.4.0
+
+* Added new type, Parser, to allow for configuration of various parsing parameters
+	* You can now specify a list of valid signing methods.  Anything outside this set will be rejected.
+	* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
+* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
+* Fixed some bugs with ECDSA parsing
+
+#### 2.3.0
+
+* Added support for ECDSA signing methods
+* Added support for RSA PSS signing methods (requires go v1.4)
+
+#### 2.2.0
+
+* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`.  Result will now be the parsed token and an error, instead of a panic.
+
+#### 2.1.0
+
+Backwards compatible API change that was missed in 2.0.0.
+
+* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
+
+#### 2.0.0
+
+There were two major reasons for breaking backwards compatibility with this update.  The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations.  There will likely be no required code changes to support this change.
+
+The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods.  Not all keys used for all signing methods have a single standard on-disk representation.  Requiring `[]byte` as the type for all keys proved too limiting.  Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys.  Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
+
+It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
+
+* **Compatibility Breaking Changes**
+	* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
+	* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
+	* `KeyFunc` now returns `interface{}` instead of `[]byte`
+	* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
+	* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
+* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.  Specific sizes are now just instances of this type.
+    * Added public package global `SigningMethodHS256`
+    * Added public package global `SigningMethodHS384`
+    * Added public package global `SigningMethodHS512`
+* Renamed type `SigningMethodRS256` to `SigningMethodRSA`.  Specific sizes are now just instances of this type.
+    * Added public package global `SigningMethodRS256`
+    * Added public package global `SigningMethodRS384`
+    * Added public package global `SigningMethodRS512`
+* Moved sample private key for HMAC tests from an inline value to a file on disk.  Value is unchanged.
+* Refactored the RSA implementation to be easier to read
+* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
+
+#### 1.0.2
+
+* Fixed bug in parsing public keys from certificates
+* Added more tests around the parsing of keys for RS256
+* Code refactoring in RS256 implementation.  No functional changes
+
+#### 1.0.1
+
+* Fixed panic if RS256 signing method was passed an invalid key
+
+#### 1.0.0
+
+* First versioned release
+* API stabilized
+* Supports creating, signing, parsing, and validating JWT tokens
+* Supports RS256 and HS256 signing methods
