-# upload-artifact
+# Upload-Artifact v2
 
-This uploads artifacts from your workflow.
+This uploads artifacts from your workflow allowing you to share data between jobs and store data once a workflow is complete.
 
 See also [download-artifact](https://github.com/actions/download-artifact).
 
+# What's new
+
+- Easier upload 
+  - Specify a wildcard pattern
+  - Specify an individual file
+  - Specify a directory (previously you were limited to only this option)
+- Upload an artifact without providing a name
+- Fix for artifact uploads sometimes not working with containers
+- Proxy support out of the box
+- Port entire action to typescript from a runner plugin so it is easier to collaborate and accept contributions
+
+Refer [here](https://github.com/actions/upload-artifact/tree/releases/v1) for the previous version
+
 # Usage
 
 See [action.yml](action.yml)
 
-Basic:
+### Upload an Individual File
 ```yaml
 steps:
-- uses: actions/checkout@v1
+- uses: actions/checkout@v2
 
 - run: mkdir -p path/to/artifact
 
 - run: echo hello > path/to/artifact/world.txt
 
-- uses: actions/upload-artifact@v1
+- uses: actions/upload-artifact@v2
   with:
     name: my-artifact
-    path: path/to/artifact
+    path: path/to/artifact/world.txt
 ```
 
+### Upload an Entire Directory
+
+```yaml
+- uses: actions/upload-artifact@v2
+  with:
+    name: my-artifact
+    path: path/to/artifact/ # or path/to/artifact
+```
+
+### Upload using a Wildcard Pattern:
+```yaml
+- uses: actions/upload-artifact@v2
+  with:
+    name: my-artifact
+    path: path/**/[abc]rtifac?/*
+```
+
+For supported wildcards along with behavior and documentation, see [@actions/glob](https://github.com/actions/toolkit/tree/master/packages/glob) which is used internally to search for files.
+
+Relative and absolute file paths are both allowed. Relative paths are rooted against the current working directory. Paths that begin with a wildcard character should be quoted to avoid being interpreted as YAML aliases.
+
+The [@actions/artifact](https://github.com/actions/toolkit/tree/master/packages/artifact) package is also used internally to handle most of the logic around uploading an artifact. There is extra documentation around upload limitations and behavior in the toolkit repo that is worth checking out.
+
+### Conditional Artifact Upload
+
 To upload artifacts only when the previous step of a job failed, use [`if: failure()`](https://help.github.com/en/articles/contexts-and-expression-syntax-for-github-actions#job-status-check-functions):
 
 ```yaml
-- uses: actions/upload-artifact@v1
+- uses: actions/upload-artifact@v2
   if: failure()
   with:
     name: my-artifact
-    path: path/to/artifact
+    path: path/to/artifact/
 ```
 
+### Uploading without an artifact name
+
+You can upload an artifact without specifying a name
+```yaml
+- uses: actions/upload-artifact@v2
+  with:
+    path: path/to/artifact/world.txt
+```
+
+If not provided, `artifact` will be used as the default name which will manifest itself in the UI after upload.
+
+### Uploading to the same artifact
+
+Each artifact behaves as a file share. Uploading to the same artifact multiple times in the same workflow can overwrite and append already uploaded files
+
+```yaml
+- run: echo hi > world.txt
+- uses: actions/upload-artifact@v2
+  with:
+    path: world.txt
+
+- run: echo howdy > extra-file.txt
+- uses: actions/upload-artifact@v2
+  with:
+    path: extra-file.txt
+
+- run: echo hello > world.txt
+- uses: actions/upload-artifact@v2
+  with:
+    path: world.txt
+```
+With the following example, the available artifact (named `artifact` which is the default if no name is provided) would contain both `world.txt` (`hello`) and `extra-file.txt` (`howdy`).
+
+### Environment Variables and Tilde Expansion
+
+You can use `~` in the path input as a substitute for `$HOME`. Basic tilde expansion is supported.
+
+```yaml
+  - run: |	
+      mkdir -p ~/new/artifact
+      echo hello > ~/new/artifact/world.txt
+  - uses: actions/upload-artifact@v2
+    with:	
+      name: 'Artifacts-V2'	
+      path: '~/new/**/*'
+```
+
+Environment variables along with context expressions can also be used for input. For documentation see [context and expression syntax](https://help.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions).
+
+```yaml
+    env:
+      name: my-artifact
+    steps:
+    - run: |	
+        mkdir -p ${{ github.workspace }}/artifact
+        echo hello > ${{ github.workspace }}/artifact/world.txt
+    - uses: actions/upload-artifact@v2
+      with:	
+        name: ${{ env.name }}-name	
+        path: ${{ github.workspace }}/artifact/**/*
+```
 
 ## Where does the upload go?
 In the top right corner of a workflow run, once the run is over, if you used this action, there will be a `Artifacts` dropdown which you can download items from. Here's a screenshot of what it looks like<br/>

 There is a trashcan icon that can be used to delete the artifact. This icon will only appear for users who have write permissions to the repository.
