+  gitdeploy receives git webhooks and runs build and deploy scripts.
+---
+
+To update or switch versions, run `webi gitdeploy@stable`.
+
+## Cheat Sheet
+
+> gitdeploy makes it easy to build and deploy static sites (or anything else)
+> from git webhooks.
+
+Works with
+
+- GitHub
+- Gitea
+- Bitbucket
+- and more ...
+
+To get set up, you'll want to copy the example scripts and dotenv:
+
+```bash
+# The example scripts are a good starting point
+rsync -av examples/ scripts/
+
+# Edit this (or delete it)
+mv scripts/dotenv .env
+```
+
+```bash
+gitdeploy run --listen :4483 --github-secret xxxxx --exec scripts/
+```
+
+When gitdeploy receives a webhook it runs `scripts/deploy.sh` with the following
+environment variables set:
+
+```bash
+GIT_REPO_ID=github.com/my-org/my-project
+
+GIT_CLONE_URL=https://github.com/my-org/my-project.git
+
+GIT_REPO_OWNER=my-org
+GIT_REPO_NAME=my-project
+GIT_REF_TYPE=branch
+GIT_REF_NAME=master
+
+GIT_DEPLOY_JOB_ID=xxxxxx
+```
+
+The example `deploy.sh` looks for `deploy.sh` in the directory matching your
+repository's URL, like this:
+
+- ./scripts/github.com/example/project/deploy.sh
+
+### How to create a build & deploy script
+
+The deploy scripts should exist in your `scripts/` directory, named after the
+repo's name.
+
+```txt
+scripts/github.com/YOUR_ORG/YOUR_PROJECT/deploy.sh
+```
+
+1. Create a directory that matches the `GIT_REPO_ID`:
+   ```bash
+   mkdir -p scripts/github.com/YOUR_ORG/YOUR_PROJECT
+   ```
+2. Create a `deploy.sh` that builds and deploys your project:
+
+   ```bash
+   #!/bin/bash
+
+   # Put bash in strict mode or bad things will happen.
+   set -u
+   set -e
+
+   # maybe you do different things with different branches
+   # in this case we just ignore all branches except for master
+   if [[ "${GIT_REF_NAME}" != "master" ]]
+   then
+       echo "Nothing to do for ${GIT_REPO_ID}#${GIT_REF_NAME}"
+       exit 0
+   fi
+
+   # make a temporary directory for the build
+   my_tmp="$(mktemp -d -t "tmp.XXXXXXXXXX")"
+   git clone --depth=1 "${GIT_CLONE_URL}" -b "${GIT_REF_NAME}" "${my_tmp}/${GIT_REPO_NAME}"
+
+   pushd "${my_tmp}/${GIT_REPO_NAME}/"
+       echo "Deploying ${GIT_REPO_ID}#${GIT_REF_NAME} ..."
+
+       # run an example build process
+       npm ci
+       npm run build
+
+       # deploy to an example staging site
+       rsync -av ./ ~/srv/staging.example.com/public/
+   popd
+
+   # clean up after the build
+   rm -rf "${my_tmp}/${GIT_REPO_NAME}/"
+   ```
+
+### How to set up a webhook
+
+1. Generate a 128-bit random string:
+   ```bash
+   xxd -l16 -ps /dev/urandom
+   ```
+2. Create a new Web Hook on your git platform:
+   - Github: `https://github.com/YOUR_ORG/YOUR_REPO/settings/hooks/new`
+   - Gitea: `https://GIT_DOMAIN/YOUR_ORG/YOUR_REPO/settings/hooks/gitea/new`
+     - Webhook: `https://YOUR_DOMAIN/api/webhooks/gitea`
+   - BitBucket:
+     `https://bitbucket.org/YOUR_ORG/YOUR_REPO/admin/addon/admin/bitbucket-webhooks/bb-webhooks-repo-admin`
+3. Set the content type to JSON.
+4. Add the Webhook URL:
+
+   ```bash
+   # Github
+   https://YOUR_DOMAIN/api/webhooks/github
+
+   # Gitea
+   https://YOUR_DOMAIN/api/webhooks/gitea
+
+   # Bitbucket
+   https://YOUR_DOMAIN/api/webhooks/bitbucket?access_token=YOUR_SECRET
+   ```
+
+### How to use ENVs (and .env)
+
+Most of the flags, such as `--port` and `--github-secret` can also be set as
+ENVs. You can create a `.env` like this, for example:
+
+```bash
+PORT=4483
+
+GITHUB_SECRET=xxxxxxxxxxx
+```
+
+See the
+[examples/dotenv](https://git.rootprojects.org/root/gitdeploy/src/branch/master/examples/dotenv)
+for more info.
