-## Example usage
-
-Basic usage for default compilation settings is like this:
-
-```yaml
-jobs:
-  test:
-    steps:
-      - uses: actions/checkout@v4
-      - uses: ilammy/msvc-dev-cmd@v1

-      # ...
-```
-
-If you want something non-default,
-like using a specific version of Visual Studio,
-or cross-compling for a different target,
-you will need to configure those settings via inputs:

-## Caveats
+## Example usage
-
-### Name conflicts with `shell: bash`
-
-Using `shell: bash` in Actions may shadow some of the paths added by MSVC.
-In particular, `link.exe` (Microsoft C linker) is prone to be shadowed by `/usr/bin/link` (GNU filesystem link tool).
-
-Unfortunately, this happens because GitHub Actions unconditionally *prepend* GNU paths when `shell: bash` is used,
-on top of any paths set by `msvc-dev-cmd`, every time at the start of each new step.
-Hence, there aren't many non-destructive options here.
-
-If you experience compilation errors where `link` complains about unreasonable command-line arguments,
-“extra operand *something-something*” – that's probably it.
-Recommended workaround is to remove `/usr/bin/link` if that interferes with your builds.
-If this is not acceptable, please file an issue, then we'll figure out something better.
-
-### Reconfiguration
-
-You can invoke `ilammy/msvc-dev-cmd` multiple times during your jobs with different inputs
-to reconfigure the environment for building with different settings
-(e.g., to target multiple architectures).
 
 ```yaml
 jobs:
-  release:
+  test:
-    steps:
+    - uses: actions/checkout@v1
-      # ...
+    - uses: ilammy/msvc-dev-cmd@v1
-      - name: Configure build for amd64
+    - name: Build something requiring CL.EXE
-        uses: ilammy/msvc-dev-cmd@v1
+      run: |
-        with:
+        cmake -G "NMake Makefiles" .
-          arch: amd64
+        nmake
-
+    # ...
-      - run: build # (for amd64)
-
-      - name: Configure build for x86
-        uses: ilammy/msvc-dev-cmd@v1
-        with:
-          arch: amd64_x86
-
-      - run: build # (for x86)
-
-      - name: Configure build for ARM64
-        uses: ilammy/msvc-dev-cmd@v1
-        with:
-          arch: amd64_arm64
-
-      - run: build # (for ARM64)
-
-      # ...
 ```
 
-This mostly works but it's not really recommended
-since Developer Command Prompt was not meant for recursive reconfiguration.
-That said, if it does not work for you, please file an issue.
-
-Consider using [`strategy.matrix`](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idstrategymatrix)
-to execute different build configuration in parallel, independent environments.

+# `@actions/core`
+
+> Core functions for setting results, logging, registering secrets and exporting variables across actions
+
+## Usage
+
+### Import the package
+
+```js
+// javascript
+const core = require('@actions/core');
+
+// typescript
+import * as core from '@actions/core';
+```
+
+#### Inputs/Outputs
+
+Action inputs can be read with `getInput`.  Outputs can be set with `setOutput` which makes them available to be mapped into inputs of other actions to ensure they are decoupled.
+
+```js
+const myInput = core.getInput('inputName', { required: true });
+
+core.setOutput('outputKey', 'outputVal');
+```
+
+#### Exporting variables
+
+Since each step runs in a separate process, you can use `exportVariable` to add it to this step and future steps environment blocks.
+
+```js
+core.exportVariable('envVar', 'Val');
+```
+
+#### Setting a secret
+
+Setting a secret registers the secret with the runner to ensure it is masked in logs.
+
+```js
+core.setSecret('myPassword');
+```
+
+#### PATH Manipulation
+
+To make a tool's path available in the path for the remainder of the job (without altering the machine or containers state), use `addPath`.  The runner will prepend the path given to the jobs PATH.
+
+```js
+core.addPath('/path/to/mytool');
+```
+
+#### Exit codes
+
+You should use this library to set the failing exit code for your action.  If status is not set and the script runs to completion, that will lead to a success.
+
+```js
+const core = require('@actions/core');
+
+try {
+  // Do stuff
+}
+catch (err) {
+  // setFailed logs the message and sets a failing exit code
+  core.setFailed(`Action failed with error ${err}`);
+}
+
+Note that `setNeutral` is not yet implemented in actions V2 but equivalent functionality is being planned.
+
+```
+
+#### Logging
+
+Finally, this library provides some utilities for logging. Note that debug logging is hidden from the logs by default. This behavior can be toggled by enabling the [Step Debug Logs](../../docs/action-debugging.md#step-debug-logs).
+
+```js
+const core = require('@actions/core');
+
+const myInput = core.getInput('input');
+try {
+  core.debug('Inside try block');
+  
+  if (!myInput) {
+    core.warning('myInput was not set');
+  }
+  
+  if (core.isDebug()) {
+    // curl -v https://github.com
+  } else {
+    // curl https://github.com
+  }
+
+  // Do stuff
+  core.info('Output to the actions build log')
+}
+catch (err) {
+  core.error(`Error ${err}, action may still succeed though`);
+}
+```
+
+This library can also wrap chunks of output in foldable groups.
+
+```js
+const core = require('@actions/core')
+
+// Manually wrap output
+core.startGroup('Do some function')
+doSomeFunction()
+core.endGroup()
+
+// Wrap an asynchronous function call
+const result = await core.group('Do something async', async () => {
+  const response = await doSomeHTTPRequest()
+  return response
+})
+```
+
+#### Action state
+
+You can use this library to save state and get state for sharing information between a given wrapper action: 
+
+**action.yml**
+```yaml
+name: 'Wrapper action sample'
+inputs:
+  name:
+    default: 'GitHub'
+runs:
+  using: 'node12'
+  main: 'main.js'
+  post: 'cleanup.js'
+```
+
+In action's `main.js`:
+
+```js
+const core = require('@actions/core');
+
+core.saveState("pidToKill", 12345);
+```
+
+In action's `cleanup.js`:
+```js
+const core = require('@actions/core');
+
+var pid = core.getState("pidToKill");
+
+process.kill(pid);
+```
