+### I want to cache a username and password for a repository
+
+You might have a repository that requires authentication.  In which case you can cache a username and password so you don't have to enter it on every push / pull. Credential helper can do this for you.
+
+```sh
+$ git config --global credential.helper cache
+# Set git to use the credential memory cache
+```
+
+```sh
+$ git config --global credential.helper 'cache --timeout=3600'
+# Set the cache to timeout after 1 hour (setting is in seconds)
+```
