+## Understanding GitHub Apps and Local Development
+
+### What is a GitHub App?
+
+A GitHub App is how bots interact with GitHub. It's:
+
+- **An account** - GitHub knows "this is the AllContributors bot"
+- **A permission system** - defines what the bot can read/write (issues, PRs,
+  files)
+- **A webhook endpoint** - where GitHub sends events (like "someone commented
+  on an issue")
+
+When someone comments `@all-contributors please add @user for code`, GitHub
+sends that comment as a webhook to whatever URL is configured in the GitHub App
+settings.
+
+### Why create your own test app?
+
+The production AllContributors app is configured to send webhooks to the
+production Vercel deployment. You can't use it for local development because:
+
+1. The webhooks go to production, not your laptop
+2. Your changes would affect real repositories
+3. You'd need to deploy every change just to test it
+
+### Local development flow:
+
+1. **Create your own GitHub App** - your personal copy with its own settings
+2. **Point its webhooks at your local machine** - so events come to you
+3. **Install it only on test repos** - isolated from production
+4. **Run the bot code locally** - make changes, test immediately
+5. **When ready** - deploy to Vercel and test with preview deployments
+
+This gives you a safe sandbox to develop in.

+
+## Local Bot Setup
+
+To test the bot locally, you need to create your own GitHub App and configure
+it to point to your local machine.
+
+<Aside type="caution">
+  Uninstall the production all-contributors bot from your user account before
+  continuing; if you don't, multiple bots will respond to your GitHub comments.
+</Aside>
+
+To get your app running against GitHub:
+
+## 1. Create a GitHub App for testing in your account:
+
+- Go to your account's GitHub
+  [developer settings](https://github.com/settings/developers)
+- Create a [new GitHub app](https://github.com/settings/apps/new)
+
+When creating your app, the fields that are required to fill out are:
+
+- **name:** Set this to any name that you like. It needs to be a globally
+  unique name on GitHub
+- **homepage url:** Set this to anything (e.g. allcontributors.org is fine)
+- **webhook url:** This also can be set to anything.
+
+The fields below also need to be filled out and the values are important:
+
+- Set **webhook secret**: to `development`
+- Set **Permissions** to the permissions [defined in the app.yml file:}
+  (https://github.com/all-contributors/all-contributors-bot/blob/main/app.yml#L54),
+  - **Repository contents:** Set to `read & write`
+  - Set **Issues** to read
+  - Set **Pull Requests** to read
+  - Set **Repository Metadata** to read
+
+\_Note that some of the settings in the `app.yml` file are commented out.\*
+
+Next:
+
+- `Subscribe to Events` should be set
+  [as defined in the app.yml](https://github.com/all-contributors/all-contributors-bot/blob/main/app.yml#L15),
+  - Check the checkbox to subscribe to the **Issue comment** event
+- Ensure **Where can this GitHub App be installed?** is set to **only this
+  account**
+
+<Picture
+  src={appInstalled}
+  formats={["avif", "webp"]}
+  alt="A screenshot ...."
+/>
+
+## 2. Configure Your GitHub App for testing
+
+You should now have create an app! Now it's time to configure it.
+
+<Picture
+  src={appCreated}
+  formats={["avif", "webp"]}
+  alt="A screenshot that shows the bottom part of the app configuration page with the question, Where can this GitHub app be installed? The option Only on this account is selected."
+/>
+
+On the app page, you will notice a side bar with several tabs including
+General, Permissions & Webhooks, and Install App.
+
+- On the General Tab of your configured app.
+
+  - scroll down to the **Private Keys** section and click the **Generate
+    Private Key** green button. This will trigger a .pem file to be created and
+    will download it to your computer (likely to your Downloads directory).
+  - Move this file so you can retrieve it later.
+  - Call it something like `allcontributorsbot.pem`.
+
+- Next, click on the Install App tab. Install the app/bot on your user
+
+**IMPORTANT**: Create a new repository for testing the bot; Then you can
+install the app on that repository only. This is important to avoid the bot
+interfering with other repositories you may have.
+
+## 3. Configure Your local to talk to the GitHub app
+
+Now that your app is created, you need to configure your local environment.
+Create a file named `.env` using the following template:
+
+```txt
+APP_ID=
+WEBHOOK_SECRET=development
+PRIVATE_KEY=
+```
+
+### .env file values
+
+- `APP_ID`: The app ID is a 7 digit numeric value. You can find it on the General tab of the developer settings
+  for your app.
+- `WEBHOOK_SECRET`: Leave this value as `development` (you set it to development when you created your app on GitHub)
+- `PRIVATE_KEY`: This key is stored in your .pem file that you downloaded above. To access the value stored in the file:
+    * CD to the `allcontributorsbot.pem.pem` file (or whatever you called it when you downloaded it above) in your favorite shell.
+    * run `openssl base64 < allcontributorsbot.pem | tr -d '\n' | pbcopy` on the file. This
+  will copy the base64 file contents onto your clipboard. Paste that value into the
+  line for `PRIVATE_KEY`
+
+## 4. Setup a test GitHub repository/with issues PR
+
+- Setup a repository under your name (the name on GitHub where the bot is
+  installed)
+- Enable issues and pull requests
+- Create an issue
+- Comment on the issue: `@all-contributors please add @jakebolam for design`
+  (replace @jakebolam with your username)
+
+To verify if the bot should have seen this goto
+[your app settings](https://github.com/settings/apps/). On the Advanced Tab,
+Click the most recent deliver to see the payload. It should look something like
+this:
+
+<Picture
+  src={deliveryComment}
+  formats={["avif", "webp"]}
+  alt="A screenshot ...."
+/>
+
+Copy the payload and save it locally in a file called
+`test-webhook-payload.json`. Also make note of the headers under the 'Headers'
+section.
+
+## 5. Send your first hook
+
+1. Install the node modules for the bot `yarn install`
+2. Run the bot `yarn start`
+3. Curl the bot (or use Postman, using the headers you got from the previous
+   step and the content from `test-webhook-payload.json`) If you're using
+   `curl`, this will look something like this:
+
+```console
+curl -vX POST http://localhost:3000/ -d @test-webhook-payload.json \
+--header "Content-Type: application/json" \
+--header "User-Agent: GitHub-Hookshot/4d63832" \
+--header "X-GitHub-Delivery: 413857f0-8b61-11eb-92be-566b7aa5f6ee" \
+--header "X-GitHub-Event: issue_comment" \
+--header "X-GitHub-Hook-ID: 297478976" \
+--header "X-GitHub-Hook-Installation-Target-ID: 105785" \
+--header "X-GitHub-Hook-Installation-Target-Type: integration" \
+--header "X-Hub-Signature: sha1=ed222e6750dc2954a422ed8dd371f9da66368104" \
+--header "X-Hub-Signature-256: sha256=04d0943f20545ac8df974466c502e4b9743d3618149b03f4ea1a9e658bf31fd0"
+```
+
+If there are no errors in the bot console, check your GitHub test issue to see
+the bot respond :tada:
+
+## Using [smee.io](https://smee.io/)
+
+Alternatively, instead of having to mock the webhook payload using `curl`, you
+can add an additional environment variable called `WEBHOOK_PROXY_URL` and set
+it to a [smee.io](https://smee.io) channel URL.
+
+Once you've done that, set the Webhook URL for you app in GitHub to the same
+channel URL and, after a server restart, your bot will be able to directly
+respond to incoming webhooks.
