+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at opensource+actions/cache@github.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

 ## Cache Limits
 
-Individual caches are limited to 200MB and a repository can have up to 2GB of caches. Once the 2GB limit is reached, older caches will be evicted based on when the cache was last accessed.
+A repository can have up to 5GB of caches. Once the 5GB limit is reached, older caches will be evicted based on when the cache was last accessed.  Caches that are not accessed within the last week will also be evicted.

+        // 2) double-up quotes - i.e. " => ""

+        //
+        //    note, replacing " with "" also works well if the arg is passed to a downstream .NET console app.
+        //    for example, the command line:
+        //          foo.exe "myarg:""my val"""
+        //    is parsed by a .NET console app into an arg array:
+        //          [ "myarg:\"my val\"" ]
+        //    which is the same end result when applying libuv quoting rules. although the actual
+        //    command line from libuv quoting rules would look like:
+        //          foo.exe "myarg:\"my val\""
+        //
+        // 3) double-up slashes that precede a quote,
+        //    e.g.  hello \world    => "hello \world"
+        //          hello\"world    => "hello\\""world"
+        //          hello\\"world   => "hello\\\\""world"
+        //          hello world\    => "hello world\\"
+        //
+        //    technically this is not required for a cmd.exe command line, or the batch argument parser.
+        //    the reasons for including this as a .cmd quoting rule are:
+        //
+        //    a) this is optimized for the scenario where the argument is passed from the .cmd file to an
+        //       external program. many programs (e.g. .NET console apps) rely on the slash-doubling rule.
+        //
+        //    b) it's what we've been doing previously (by deferring to node default behavior) and we
+        //       haven't heard any complaints about that aspect.
+        //
+        // note, a weakness of the quoting rules chosen here, is that % is not escaped. in fact, % cannot be
+        // escaped when used on the command line directly - even though within a .cmd file % can be escaped
+        // by using %%.
+        //
+        // the saving grace is, on the command line, %var% is left as-is if var is not defined. this contrasts
+        // the line parsing rules within a .cmd file, where if var is not defined it is replaced with nothing.
+        //
+        // one option that was explored was replacing % with ^% - i.e. %var% => ^%var^%. this hack would
+        // often work, since it is unlikely that var^ would exist, and the ^ character is removed when the
+        // variable is used. the problem, however, is that ^ is not removed when %* is used to pass the args
+        // to an external program.
+        //
+        // an unexplored potential solution for the % escaping problem, is to create a wrapper .cmd file.

+        //    is parsed by a .NET console app into an arg array:
+        //          [ "myarg:\"my val\"" ]
+        //    which is the same end result when applying libuv quoting rules. although the actual
+        //    command line from libuv quoting rules would look like:
+        //          foo.exe "myarg:\"my val\""
+        //
+        // 3) double-up slashes that precede a quote,
+        //    e.g.  hello \world    => "hello \world"
+        //          hello\"world    => "hello\\""world"
+        //          hello\\"world   => "hello\\\\""world"
+        //          hello world\    => "hello world\\"
+        //
+        //    technically this is not required for a cmd.exe command line, or the batch argument parser.
+        //    the reasons for including this as a .cmd quoting rule are:
+        //
+        //    a) this is optimized for the scenario where the argument is passed from the .cmd file to an
+        //       external program. many programs (e.g. .NET console apps) rely on the slash-doubling rule.
+        //
+        //    b) it's what we've been doing previously (by deferring to node default behavior) and we
+        //       haven't heard any complaints about that aspect.
+        //
+        // note, a weakness of the quoting rules chosen here, is that % is not escaped. in fact, % cannot be
+        // escaped when used on the command line directly - even though within a .cmd file % can be escaped
+        // by using %%.
+        //
+        // the saving grace is, on the command line, %var% is left as-is if var is not defined. this contrasts
+        // the line parsing rules within a .cmd file, where if var is not defined it is replaced with nothing.
+        //
+        // one option that was explored was replacing % with ^% - i.e. %var% => ^%var^%. this hack would
+        // often work, since it is unlikely that var^ would exist, and the ^ character is removed when the
+        // variable is used. the problem, however, is that ^ is not removed when %* is used to pass the args
+        // to an external program.
+        //
+        // an unexplored potential solution for the % escaping problem, is to create a wrapper .cmd file.
+        // % can be escaped within a .cmd file.

+## C# - NuGet
+Using [NuGet lock files](https://docs.microsoft.com/nuget/consume-packages/package-references-in-project-files#locking-dependencies):
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/.nuget/packages
+    key: ${{ runner.os }}-nuget-${{ hashFiles('**/packages.lock.json') }}
+    restore-keys: |
+      ${{ runner.os }}-nuget-
+```
+
+Depending on the environment, huge packages might be pre-installed in the global cache folder.
+If you do not want to include them, consider to move the cache folder like below.
+>Note: This workflow does not work for projects that require files to be placed in user profile package folder
+```yaml
+env:
+  NUGET_PACKAGES: ${{ github.workspace }}/.nuget/packages
+steps:
+  - uses: actions/cache@v1
+    with:
+      path: ${{ github.workspace }}/.nuget/packages
+      key: ${{ runner.os }}-nuget-${{ hashFiles('**/packages.lock.json') }}
+      restore-keys: |
+        ${{ runner.os }}-nuget-
+```
+
+## Elixir - Mix
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: deps
+    key: ${{ runner.os }}-mix-${{ hashFiles(format('{0}{1}', github.workspace, '/mix.lock')) }}
+    restore-keys: |
+      ${{ runner.os }}-mix-
+```
+
+## Go - Modules
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/go/pkg/mod
+    key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }}
+    restore-keys: |
+      ${{ runner.os }}-go-
+```
+
+## Haskell - Cabal
+
+We cache the elements of the Cabal store separately, as the entirety of `~/.cabal` can grow very large for projects with many dependencies.
+
+```yaml
+- uses: actions/cache@v1
+  name: Cache ~/.cabal/packages
+  with:
+    path: ~/.cabal/packages
+    key: ${{ runner.os }}-${{ matrix.ghc }}-cabal-packages
+- uses: actions/cache@v1
+  name: Cache ~/.cabal/store
+  with:
+    path: ~/.cabal/store
+    key: ${{ runner.os }}-${{ matrix.ghc }}-cabal-store
+- uses: actions/cache@v1
+  name: Cache dist-newstyle
+  with:
+    path: dist-newstyle
+    key: ${{ runner.os }}-${{ matrix.ghc }}-dist-newstyle
+```
+
+## Java - Gradle
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/.gradle/caches
+    key: ${{ runner.os }}-gradle-${{ hashFiles('**/*.gradle') }}
+    restore-keys: |
+      ${{ runner.os }}-gradle-
+```
+
+## Java - Maven
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/.m2/repository
+    key: ${{ runner.os }}-maven-${{ hashFiles('**/pom.xml') }}
+    restore-keys: |
+      ${{ runner.os }}-maven-
+```
+
+## Node - npm
+
+For npm, cache files are stored in `~/.npm` on Posix, or `%AppData%/npm-cache` on Windows. See https://docs.npmjs.com/cli/cache#cache
+
+>Note: It is not recommended to cache `node_modules`, as it can break across Node versions and won't work with `npm ci`
+
+### macOS and Ubuntu
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/.npm
+    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
+    restore-keys: |
+      ${{ runner.os }}-node-
+```
+
+### Windows
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~\AppData\Roaming\npm-cache
+    key: ${{ runner.os }}-node-${{ hashFiles('**\package-lock.json') }}
+    restore-keys: |
+      ${{ runner.os }}-node-
+```
+
+### Using multiple systems and `npm config`
+
+```yaml  
+- name: Get npm cache directory
+  id: npm-cache
+  run: |
+    echo "::set-output name=dir::$(npm config get cache)"
+- uses: actions/cache@v1
+  with:
+    path: ${{ steps.npm-cache.outputs.dir }}
+    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
+    restore-keys: |
+      ${{ runner.os }}-node-
+```
+
+## Node - Yarn
+The yarn cache directory will depend on your operating system and version of `yarn`. See https://yarnpkg.com/lang/en/docs/cli/cache/ for more info.
+
+```yaml
+- name: Get yarn cache
+  id: yarn-cache
+  run: echo "::set-output name=dir::$(yarn cache dir)"
+
+- uses: actions/cache@v1
+  with:
+    path: ${{ steps.yarn-cache.outputs.dir }}
+    key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-yarn-
+```
+
+## PHP - Composer
+
+```yaml  
+- name: Get Composer Cache Directory
+  id: composer-cache
+  run: |
+    echo "::set-output name=dir::$(composer config cache-files-dir)"
+- uses: actions/cache@v1
+  with:
+    path: ${{ steps.composer-cache.outputs.dir }}
+    key: ${{ runner.os }}-composer-${{ hashFiles('**/composer.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-composer-
+```
+
+## Python - pip
+
+For pip, the cache directory will vary by OS. See https://pip.pypa.io/en/stable/reference/pip_install/#caching
+
+Locations:
+ - Ubuntu: `~/.cache/pip`
+ - Windows: `~\AppData\Local\pip\Cache`
+ - macOS: `~/Library/Caches/pip`
+
+### Simple example
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/.cache/pip
+    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
+    restore-keys: |
+      ${{ runner.os }}-pip-
+```
+
+Replace `~/.cache/pip` with the correct `path` if not using Ubuntu.
+
+### Multiple OS's in a workflow
+
+```yaml
+- uses: actions/cache@v1
+  if: startsWith(runner.os, 'Linux')
+  with:
+    path: ~/.cache/pip
+    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
+    restore-keys: |
+      ${{ runner.os }}-pip-
+
+- uses: actions/cache@v1
+  if: startsWith(runner.os, 'macOS')
+  with:
+    path: ~/Library/Caches/pip
+    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
+    restore-keys: |
+      ${{ runner.os }}-pip-
+
+- uses: actions/cache@v1
+  if: startsWith(runner.os, 'Windows')
+  with:
+    path: ~\AppData\Local\pip\Cache
+    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
+    restore-keys: |
+      ${{ runner.os }}-pip-
+```
+
+### Using a script to get cache location
+
+> Note: This uses an internal pip API and may not always work
+```yaml
+- name: Get pip cache
+   id: pip-cache
+   run: |
+     python -c "from pip._internal.locations import USER_CACHE_DIR; print('::set-output name=dir::' + USER_CACHE_DIR)"
+
+- uses: actions/cache@v1
+  with:
+    path: ${{ steps.pip-cache.outputs.dir }}
+    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
+    restore-keys: |
+      ${{ runner.os }}-pip-
+```
+
+## R - renv
+
+For renv, the cache directory will vary by OS. Look at https://rstudio.github.io/renv/articles/renv.html#cache
+
+Locations:
+ - Ubuntu: `~/.local/share/renv`
+ - macOS: `~/Library/Application Support/renv`
+ - Windows: `%LOCALAPPDATA%/renv`
+
+### Simple example
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/.local/share/renv
+    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-renv-
+```
+
+Replace `~/.local/share/renv` with the correct `path` if not using Ubuntu.
+
+### Multiple OS's in a workflow
+
+```yaml
+- uses: actions/cache@v1
+  if: startsWith(runner.os, 'Linux')
+  with:
+    path: ~/.local/share/renv
+    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-renv-
+
+- uses: actions/cache@v1
+  if: startsWith(runner.os, 'macOS')
+  with:
+    path: ~/Library/Application Support/renv
+    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-renv-
+
+- uses: actions/cache@v1
+  if: startsWith(runner.os, 'Windows')
+  with:
+    path: ~\AppData\Local\renv
+    key: ${{ runner.os }}-renv-${{ hashFiles('**/renv.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-renv-
+```
+
+## Ruby - Bundler
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: vendor/bundle
+    key: ${{ runner.os }}-gems-${{ hashFiles('**/Gemfile.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-gems-
+```
+When dependencies are installed later in the workflow, we must specify the same path for the bundler.
+
+```yaml
+- name: Bundle install
+  run: |
+    bundle config path vendor/bundle
+    bundle install --jobs 4 --retry 3
+```
+
+## Rust - Cargo
+
+```yaml
+- name: Cache cargo registry
+  uses: actions/cache@v1
+  with:
+    path: ~/.cargo/registry
+    key: ${{ runner.os }}-cargo-registry-${{ hashFiles('**/Cargo.lock') }}
+- name: Cache cargo index
+  uses: actions/cache@v1
+  with:
+    path: ~/.cargo/git
+    key: ${{ runner.os }}-cargo-index-${{ hashFiles('**/Cargo.lock') }}
+- name: Cache cargo build
+  uses: actions/cache@v1
+  with:
+    path: target
+    key: ${{ runner.os }}-cargo-build-target-${{ hashFiles('**/Cargo.lock') }}
+```
+
+## Scala - SBT
+
+```yaml
+- name: Cache SBT ivy cache
+  uses: actions/cache@v1
+  with:
+    path: ~/.ivy2/cache
+    key: ${{ runner.os }}-sbt-ivy-cache-${{ hashFiles('**/build.sbt') }}
+- name: Cache SBT
+  uses: actions/cache@v1
+  with:
+    path: ~/.sbt
+    key: ${{ runner.os }}-sbt-${{ hashFiles('**/build.sbt') }}
+```
+
+## Swift, Objective-C - Carthage
+
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: Carthage
+    key: ${{ runner.os }}-carthage-${{ hashFiles('**/Cartfile.resolved') }}
+    restore-keys: |
+      ${{ runner.os }}-carthage-

+## Swift, Objective-C - CocoaPods
+
+```yaml
+- uses: actions/cache@v1

+    path: Pods
+    key: ${{ runner.os }}-pods-${{ hashFiles('**/Podfile.lock') }}
+    restore-keys: |
+      ${{ runner.os }}-pods-
+```
+
+## Swift - Swift Package Manager
+
+```yaml
+- uses: actions/cache@v1
