 ### Adding the command line parameter
-- conf/default-cli-options.js: add the property 'shareableCache' with a default of false. It should be put in the section with the other cache variables, below cacheStrategy. 
-- docs/src/use/command-line-interface.md: Add an explanation of the 'shareable-cache' variable with the other cache variables: "By default, an eslintcache contains full file paths and thus cannot readily be shared across developers or ci machines. "False" is that default. "True" changes the internal storage to store a relative path to the process execution directory, thus making the eslintcache shareable across developers and ci machines. . If you change this setting, you must regenerate your entire eslint cache."
-- eslint-helpers.js: add shareableCache variable (set to false) to the processOptions, and make sure it must be a boolean. 
-- lib/options.js: Add an option 'shareable-cache' of type Boolean with a nice description for people to read: By default, an eslintcache contains full file paths and thus cannot readily be shared across developers or ci machines. "False" is that default. "True" changes the internal storage to store a relative path to the process execution directory, thus making the eslintcache shareable across developers and ci machines. . If you change this setting, you must regenerate your entire eslint cache.
-- lib/cli.js: Add the shareableCache option, defaulted to false, in the translateOptions function.

 ### Changing cache file serialization
 - `lib/cli-engine/lint-result-cache.js`: Add the properties `cwd` and `shareableCache` to the `LintResultCache` class. `cwd` is a string, the current working directory. `shareableCache` is a boolean, the result of the user's passed in command line parameter. Use these values in two main places:
