-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-preview
   with:
     name: my-artifact
-    path: path/to/artifact
+    path: path/to/artifact/world.txt
 ```
 
+### Upload an Entire Directory
+
+```yaml
+- uses: actions/upload-artifact@v2-preview
+  with:
+    name: my-artifact
+    path: path/to/artifact/ # or path/to/artifact
+```
+
+### Upload using a Wildcard Pattern:
+```yaml
+- uses: actions/upload-artifact@v2-preview
+  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.
+
+### 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-preview
   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-preview
+  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-preview
+  with:
+    path: world.txt
+
+- run: echo howdy > extra-file.txt
+- uses: actions/upload-artifact@v2-preview
+  with:
+    path: extra-file.txt
+
+- run: echo hello > world.txt
+- uses: actions/upload-artifact@v2-preview
+  with:
+    path: world.txt
+```
+With the following example, the available artifact (named `artifact`) would contain both `world.txt` (`hello`) and `extra-file.txt` (`howdy`).
