 ## 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.  Caches that are not accessed within the last week will also be evicted.
+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.

+## 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
+

+
+## 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

+
+## 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-
+```
+
+### 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') }}

+      ${{ runner.os }}-renv-
+```
+
+Replace `~/.local/share/renv` with the correct `path` if not using Ubuntu.

+    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
