-
-Automatically add an issue or pull request to specific [GitHub Project](https://help.github.com/articles/about-project-boards/) when you __create__ and/or __label__ them. By default, the issues are assigned to the __`To do`__ column and the pull requests to the __`In progress`__ one, so make sure you have those columns in your project dashboard. But the workflow __allowed you to specify the column name as input__, so you can assign the issues/PRs based on a set of conditions to a specific column of a specific project.
-
-## Latest features:
-
-* included `issue_comment` as trigger for this action.
-* added project pagination for searching 100+ GitHub projects.
-
-## Acknowledgment & Motivations
-
-This action has been modified from the original action from [masutaka](https://github.com/masutaka/github-actions-all-in-one-project). I needed to fix it as the original docker container would not build. Also I think the GitHub Action syntax changed a bit.
-
-I would like to thank @SunRunAway for adding the labelling functionality and custom column input.
-
-## Inputs
-
-### `project`
-
-**Required** The url of the project to be assigned to.
-
-### `column_name`
-
-The column name of the project, defaults to `'To do'` for issues and `'In progress'` for pull requests.
-
-## Example usage
-
-Examples of action:
-
-### Repository project
-
-```yaml
-name: Auto Assign to Project(s)
-
-on:
-  issues:
-    types: [opened, labeled]
-  pull_request:
-    types: [opened, labeled]
-  issue_comment:
-    types: [created]
-env:
-  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
-
-jobs:
-  assign_one_project:
-    runs-on: ubuntu-latest
-    name: Assign to One Project
-    steps:
-    - name: Assign NEW issues and NEW pull requests to project 2
-      uses: srggrs/assign-one-project-github-action@1.2.1
-      if: github.event.action == 'opened'
-      with:
-        project: 'https://github.com/srggrs/assign-one-project-github-action/projects/2'
-
-    - name: Assign issues and pull requests with `bug` label to project 3
-      uses: srggrs/assign-one-project-github-action@1.2.1
-      if: |
-        contains(github.event.issue.labels.*.name, 'bug') ||
-        contains(github.event.pull_request.labels.*.name, 'bug')
-      with:
-        project: 'https://github.com/srggrs/assign-one-project-github-action/projects/3'
-        column_name: 'Labeled'
-```
-
-#### __Notes__
-Be careful of using the conditions above (opened and labeled issues/PRs) because in such workflow, if the issue/PR is opened and labeled at the same time, it will be assigned to __both__ projects!
-
-
-You can use any combination of conditions. For example, to assign new issues or issues labeled with 'mylabel' to a project column, use:
-```yaml
-...
-
-if: |
-  github.event_name == 'issues' &&
-  (
-    github.event.action == 'opened' ||
-    contains(github.event.issue.labels.*.name, 'mylabel')
-  )
-...
-```
-
-### Organisation or User project
-
-Generate a token from the Organisation settings or User Settings and add it as a secret in the repository secrets as `MY_GITHUB_TOKEN`
-
-```yaml
-name: Auto Assign to Project(s)
-
-on:
-  issues:
-    types: [opened, labeled]
-  pull_request_target:
-    types: [opened, labeled]
-  issue_comment:
-    types: [created]
-env:
-  MY_GITHUB_TOKEN: ${{ secrets.MY_GITHUB_TOKEN }}
-
-jobs:
-  assign_one_project:
-    runs-on: ubuntu-latest
-    name: Assign to One Project
-    steps:
-    - name: Assign NEW issues and NEW pull requests to project 2
-      uses: srggrs/assign-one-project-github-action@1.2.1
-      if: github.event.action == 'opened'
-      with:
-        project: 'https://github.com/srggrs/assign-one-project-github-action/projects/2'
-
-    - name: Assign issues and pull requests with `bug` label to project 3
-      uses: srggrs/assign-one-project-github-action@1.2.1
-      if: |
-        contains(github.event.issue.labels.*.name, 'bug') ||
-        contains(github.event.pull_request.labels.*.name, 'bug')
-      with:
-        project: 'https://github.com/srggrs/assign-one-project-github-action/projects/3'
-        column_name: 'Labeled'
-```
