-# Project Name
+[![Docker Repository on Quay](https://quay.io/repository/avanier/gitea-resource/status "Docker Repository on Quay")](https://quay.io/repository/avanier/gitea-resource)
 
-TODO: Write a project description
+# gitea-resource
+
+A Concourse resource to interact with Gitea.
 
 ## Installation
 
-TODO: Describe the installation process
+```yaml
+resource_types:
+  - name: gitea-pr
+    type: registry-image
+    source:
+      repository: quay.io/avanier/gitea-resource
+      tag: latest-pr
+
+resrouces:
+  - name: some-repo-pr
+    type: gitea-pr
+    source:
+      access_token: ((my_cred.token))
+      repo: some-repo
+      owner: some_user_or_org
+      hostname: privatehost.example
+      port: 443 # default, optional
+      insecure: false # default, optional, true uses http instead of https
+      skip_ssl_verification: false # default, optional, ignore invalid certificates
+```
 
 ## Usage
 
-TODO: Write usage instructions
+### `check`
 
-## Contributing
+This resource is opinionated, and does not allow you to track every commit on
+every PR. All it does for now is allow you to know when new PRs are created, and
+it returns the PR number as a ref.
 
-1.  Create your feature branch: `git checkout -b feature/my-new-feature`
-2.  Commit your changes: `git commit -am 'Add some feature'`
-3.  Push to the branch: `git push origin my-new-feature`
-4.  Submit a pull request :D
+### `in`
 
-## Credits
+When you `get` a ref, the resource will provide the raw Gitea API payload, and
+the Concourse metadata for that PR as the following files:
 
-TODO: Write credits
+```plaintext
+some-repo-pr/pr.json
+some-repo-pr/metadata.json
+```
 
+The intent is to parse this with `jq` in a separate task to get the branch, and
+template a pipeline for every PR with the [`fly-resource`][fly-resource]. It's
+the only way to avoid PR race conditions.

+## FAQ
+
+- **I'd like to set the CI status for those PRs.** It's an incoming feature. I
+  organized my code to be able to have a single codebase to do all the
+  operations on Gitea. Right now only listing and querying PRs is implemented,
+  but that's why the `base` image is separate from the `pr` image. I'll
+  eventually probably implement `singlepr` and `release`. The [`pr`][pr-image] image only
+  has one extra layer which puts the right commands in the `$PATH`.
