-Triggers can be used to force a rebuild of a specific branch or tag with an API
-call.
+Triggers can be used to force a rebuild of a specific branch, tag or commit,
+with an API call.
 
 ## Add a trigger
 
+You can add a new trigger by going to your project's **Settings > Triggers**.
+The **Add trigger** button will create a new token which you can then use to
+trigger a rebuild of this particular project.
+
+Once at least one trigger is created, on the **Triggers** page you will find
+some descriptive information on how you can
+
+Every new trigger you create, gets assigned a different token which you can
+then use inside your scripts or `.gitlab-ci.yml`. You also have a nice
+overview of the time the triggers were last used.
+

+
+## Revoke a trigger
+
+You can revoke a trigger any time by going at your project's
+**Settings > Triggers** and hitting the **Revoke** button. The action is
+irreversible.
+
+## Trigger a build
+
+To trigger a build you need to send a `POST` request to GitLab's API endpoint:
+
+```
+POST /projects/:id/trigger/builds
+```
+
+The required parameters are the trigger's `token` and the Git `ref` on which
+the trigger will be performed. Valid refs are the branch, the tag or the commit
+SHA. The `:id` of a project can be found by [querying the API](../api/projects.md)
+or by visiting the **Triggers** page which provides self-explanatory examples.
+
+When a rebuild is triggered, the information is exposed in GitLab's UI under
+the **Builds** page and the builds are marked as `triggered`.
+
+![Marked rebuilds as triggered on builds page](img/builds_page.png)
+
+---
+
+You can see which trigger caused the rebuild by visiting the single build page.
+The token of the trigger is exposed in the UI as you can see from the image
+below.
+
+![Marked rebuilds as triggered on a single build page](img/trigger_single_build.png)
+
+---
+
+See the [Examples](#examples) section for more details on how to actually
+trigger a rebuild.
+
+## Pass build variables to a trigger
+
+You can pass any number of arbitrary variables in the trigger API call and they
+will be available in GitLab CI so that they can be used in your `.gitlab-ci.yml`
+file. The parameter is of the form:
+
+```
+variables[key]=value
+```
+
+This information is also exposed in the UI.
+
+![Build variables in UI](img/trigger_variables.png)
+
+---
+
+See the [Examples](#examples) section below for more details.
+
+## Examples
+
+Using cURL you can trigger a rebuild with minimal effort, for example:
+
+```bash
+curl -X POST \
+     -F token=TOKEN \
+     -F ref=master \
+     https://gitlab.com/api/v3/projects/9/trigger/builds
+```
+
+In this case, the project with ID `9` will get rebuilt on `master` branch.
+
+You can also use triggers in your `.gitlab-ci.yml`. Let's say that you have
+two projects, A and B, and you want to trigger a rebuild on the `master`
+branch of project B whenever a tag on project A is created.
+
+```yaml
+build_docs:
+  stage: deploy
+  script:
+    - "curl -X POST -F token=TOKEN -F ref=master https://gitlab.com/api/v3/projects/9/trigger/builds"
+  only:
+  - tags
+```
