+# DevSkiller TalentScore - Upload task action
+
+This GitHub Action uploads custom programming tasks to the DevSkiller TalentScore platform. It allows you to easily integrate the upload process into your CI/CD pipeline.
+
+## Inputs
+
+### `api_key`
+**Required**: The TalentScore API key. This key is needed to authenticate the upload request.
+
+### `path`
+**Required**: The path to the programming task directory that contains the task source code to upload.
+
+### `id`
+**Optional**: The ID of the programming task you want to update on the TalentScore platform. If not provided, the code task directory should contain a [metadata.yaml file](metadata-file-structure.md).
+
+### `publish`
+**Optional**: If set to `true` (default), the task will be published automatically after a successful build.
+
+## Example
+
+```yaml
+name: Sample task upload
+
+on:
+  push:
+    branches:
+      - master
+
+jobs:
+  upload-task:
+    runs-on: ubuntu-latest
+
+    steps:
+      - uses: actions/checkout@v2
+      - uses: Devskiller/talentscore-upload-task-action@v1.0.0
+        with:
+          api_key: ${{ secrets.TALENTSCORE_API_KEY }}
+          id: fe3217a6-e085-47dd-afff-025be5355d87
+          path: ./src
+```
+
+## How to prepare a custom programming task
+Please see: [Creating custom tasks](https://help.devskiller.com/space/TSG/2893873179/Creating+Custom+Tasks)

+# Metadata file structure
+The file stores programming task details in the form of YAML key-value pairs, with the following fields:
+
+- **uuid**: ID of the task. With it you will be able to update tasks. You can use the existing one or generate an unique value using [generators](https://www.uuidgenerator.net/)
+- **title**: title of a task
+- **question**:  question which will be presented to the candidate
+- **type**: `PROGRAMMING` or `CODE_REVIEW` 
+- **difficulty**: difficulty level, one of `EASY`, `MEDIUM`, `HARD`
+- **tags**: task tags, ie. what kind of knowledge this questions tests
+- **points**: default number of points for this task
+- **duration**: default time duration in the ISO 8601 duration format  
+- **projectType**: technology associated with the task, e.g.: `CMAKE`, `NODEJS`, `MAVEN`
+- **projectTypeVersion**: specific version of the technology, e.g.: `NODEJS16`, `GCC11`
+
+## Example
+
+```yaml
+uuid: aee4ae94-5709-4917-8dde-fa54b91f84cf
+title: Java | Sample Calculator task
+question: |-
+  Your task is to create a simple calculator capable of adding, subtracting, multiplying and dividing two numbers.
+type: PROGRAMMING
+difficulty: EASY
+tags: ['C++', 'Basics']
+points: 20
+duration: PT1H
