+# Install
+
+Add this file to `_plugins` in the root of your Jekyll site.
+
+Add dependencies these dependencie to your sites Gemfile
+
+```
+gem 'json'
+gem 'hash-joiner'
+gem 'open-uri-cached'
+```
+
+# Run
+`bundle install`
+`jekyll build`
+`jekyll
+
+# Configure
+
+This plugin reads settings from the `_config.yml` file. Add settings as attributes or an array of attributes for multiple files.
+
+## Example
+
+```yml
+jekyll_get:
+  data: team
+  json: 'https://18f.gsa.gov/hub/api/team/'
+```
+
+Or
+
+```yml
+jekyll_get:
+  - data: team
+    json: 'https://18f.gsa.gov/hub/api/team/'
+  - data: projects
+    json: 'https://18f.gsa.gov/hub/api/projects/'
+```
+
+Use in a liquid template as if it were a local data file:
+
+```liquid
+{% for member in site.data.team %}
+  Hello {{member[1].first_name}}
+{% endfor %}
+```
+
+Optionally, set a cache attribute to save a local copy of the data in the `_data` directory:
+
+```yml
+jekyll_get:
+  - data: team
+    json: 'https://18f.gsa.gov/hub/api/team/'
+    cache: true
+  - data: projects
+    json: 'https://18f.gsa.gov/hub/api/projects/'
+    cache: true
+  - data: pif_team
+    json: 'https://18f.gsa.gov/hub/api/pif_team/'
+    cache: true
+  - data: pif_projects
+    json: 'https://18f.gsa.gov/hub/api/pif_projects/'
+    cache: true
+```
