   - `grunt shell:compile_dev --path=about-us` to re-compile only template(s) which serve about-us path in URL.
 - To fix eslint errors run `npm run eslint`
 
-### Sections
-The codebase is divided into different sections. Passing `--section=[all|app|app_2]` to almost all grunt commands causes to run it on the specified section (excluding tests since it should run on the whole source code).
-
-Current sections are:
-- `app` represents current version of the website including `app`, `static`, `landing_pages` folders in the source code.
-- `app_2` is the next version which its source code is mainly inside the `app_2` folders.
-- `all` denotes to all available sections and is the default value if `--section` is not specified.
-
-Although section is mandatory for release, but it is optional for the rest of commands as there is a default value (`all`).
-
 ## Release
 
 ```
-grunt release --{release type}=1 --section=app|app_2 [--cleanup] [--reset]
+grunt release --{release type}=1 [--cleanup] [--reset]
 ```
