Update test

Currently it's a unstructured map[string]string that gets copied into
a Result.ExtraData after detection, but we might want to revisit this
decision when we get more handlers.

+# Testing
+
+Most testing is handled automatically by our GitHub Actions workflows.
+
+## Local GitHub Action Testing
+
+In some cases you may wish to submit changes to the Trufflehog GitHub Action. Unfortunately GitHub does not provide a 1st-party testing environment for testing actions outside of GitHub Actions.
+
+Fortunately [nektos/act](https://github.com/nektos/act) enables local testing of GitHub Actions.
+
+### Instructions
+
+1. Please follow [the installation instructions](http://https://github.com/nektos/act#installation) for your OS.
+2. The first run of `act` will ask you to specify an image. `Medium` should suffice.
+3. You'll need to configure a personal-access-token(PAT) with: `repo:status`, `repo_deployment`, and `public_repo` permissions.
+4. Set an environment variable named `GITHUB_TOKEN` with the PAT from the previous step as the value: `$ export GITHUB_TOKEN=<your_PAT>`
+5. Run the following command from the repository root: `act pull_request -j test -W .github/workflows/secrets.yml -s GITHUB_TOKEN --defaultbranch main`
+6. If the job was successful, you should expect to see output from the scanner showing several detected secrets.
+7. If you want to omit the context of a pull request event and just test that the action starts successfully, run: `act -j test -W .github/workflows/secrets.yml -s GITHUB_TOKEN --defaultbranch main`

-# What's new in v3?
+# :newspaper: What's new in v3?
 
 TruffleHog v3 is a complete rewrite in Go with many new powerful features.
 
 - We've **added over 700 credential detectors that support active verification against their respective APIs**.
-- We've also added native **support for scanning GitHub, GitLab, filesystems, and S3**.
+- We've also added native **support for scanning GitHub, GitLab, filesystems, S3, GCS and Circle CI**.
 - **Instantly verify private keys** against millions of github users and **billions** of TLS certificates using our [Driftwood](https://trufflesecurity.com/blog/driftwood) technology.
+- Scan binaries and other file formats
+- Available as a GitHub Action and a pre-commit hook
 
 
 ## What is credential verification?
-For every potential credential that is detected, we've painstakingly implemented programatic verification against the API that we think it belongs to. Verification eliminates false positives. For example, the [AWS credential detector](pkg/detectors/aws/aws.go) performs a `GetCallerIdentity` API call against the AWS API to verify if an AWS credential is active.

-## Installation
-
-Several options:
-
-### 1. Go
-```
-git clone https://github.com/trufflesecurity/trufflehog.git
-
-cd trufflehog; go install
-```
-
-### 2. [Release binaries](https://github.com/trufflesecurity/trufflehog/releases)
-
-### 3. Docker
-
-
-> Note: Apple M1 hardware users should run with `docker run --platform linux/arm64` for better performance.
-
-#### **Most users**
-
-```bash
-docker run -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --repo https://github.com/trufflesecurity/test_keys
-```
-
-#### **Apple M1 users**
-
-The `linux/arm64` image is better to run on the M1 than the amd64 image.
-Even better is running the native darwin binary available, but there is no container image for that.
-
-```bash
-docker run --platform linux/arm64 -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --repo https://github.com/trufflesecurity/test_keys 
-```
-
-### 4. Pip (help wanted)
-
-It's possible to distribute binaries in pip wheels.

-## Use as a library
+# Regex Detector (alpha)
 
-Currently, trufflehog is in heavy development and no guarantees can be made on
-the stability of the public APIs at this time.
+Trufflehog supports detection and verification of custom regular expressions.
+For detection, at least one **regular expression** and **keyword** is required.
+A **keyword** is a fixed literal string identifier that appears in or around
+the regex to be detected. To allow maximum flexibility for verification, a
+webhook is used containing the regular expression matches.
 
-## Contributors
+Trufflehog will send a JSON POST request containing the regex matches to a
+configured webhook endpoint. If the endpoint responds with a `200 OK` response
+status code, the secret is considered verified.
+
+**NB:** This feature is alpha and subject to change.
+
+## Regex Detector Example
+
+```yaml
+# config.yaml
+detectors:
+- name: hog detector
+  keywords:
+  - hog
+  regex:
+    adjective: hogs are (\S+)
+  verify:
+  - endpoint: http://localhost:8000/
+    # unsafe must be set if the endpoint is HTTP
+    unsafe: true
+    headers:
+    - 'Authorization: super secret authorization header'
+```
+
+```
+$ trufflehog filesystem /tmp --config config.yaml --only-verified
+🐷🔑🐷  TruffleHog. Unearth your secrets. 🐷🔑🐷
+
+Found verified result 🐷🔑
+Detector Type: CustomRegex
+Decoder Type: PLAIN
+Raw result: hogs are cool
+File: /tmp/hog-facts.txt
+```
+
+## Verification Server Example (Python)
+
+Unless you run a verification server, secrets found by the custom regex
+detector will be unverified. Here is an example Python implementation of a
+verification server for the above `config.yaml` file.
+
+```python
+import json
+from http.server import BaseHTTPRequestHandler, HTTPServer
+
+AUTH_HEADER = 'super secret authorization header'
+
+
+class Verifier(BaseHTTPRequestHandler):
+    def do_GET(self):
+        self.send_response(405)
+        self.end_headers()
+
+    def do_POST(self):
+        try:
+            if self.headers['Authorization'] != AUTH_HEADER:
+                self.send_response(401)
+                self.end_headers()
+                return
+
+            # read the body
+            length = int(self.headers['Content-Length'])
+            request = json.loads(self.rfile.read(length))
+            self.log_message("%s", request)
+
+            # check the match
+            if request['hog detector']['adjective'][-1] == 'cool':
+                self.send_response(200)
+                self.end_headers()
+            else:
+                # any other response besides 200
+                self.send_response(406)
+                self.end_headers()
+        except Exception:
+            self.send_response(400)

+### Verification indeterminacy
+
+There are two types of reasons that secret verification can fail:
+* The candidate secret is not actually a valid secret.
+* Something went wrong in the process unrelated to the candidate secret, such as a transient network error or an unexpected API response.
+
+In Trufflehog parlance, the first type of verification response is called _determinate_ and the second type is called _indeterminate_. Verification code should distinguish between the two by returning an error object in the result struct **only** for indeterminate failures. In general, a verifier should return an error (indicating an indeterminate failure) in all cases that haven't been explicitly identified as determinate failure states.
+
+For example, consider a hypothetical authentication endpoint that returns `200 OK` for valid credentials and `403 Forbidden` for invalid credentials. The verifier for this endpoint could make an HTTP request and use the response status code to decide what to return:
+* A `200` response would indicate that verification succeeded. (Or maybe any `2xx` response.)
+* A `403` response would indicate that verification failed **determinately** and no error object should be returned.
+* Any other response would indicate that verification failed **indeterminately** and an error object should be returned.
