 ### New Version Info
 
-#### Author's Instructions
-- [ ] Derive a new `MAJOR.MINOR.PATCH` version number. Increment the:
-    - `MAJOR` version when you make incompatible API changes
-    - `MINOR` version when you add functionality in a backwards-compatible manner
-    - `PATCH` version when you make backwards-compatible bug fixes
-- [ ] Update [CHANGELOG.md](https://github.com/scrooloose/nerdtree/blob/master/CHANGELOG.md), following the established pattern.
-#### Collaborator's Instructions
-- [ ] Review [CHANGELOG.md](https://github.com/scrooloose/nerdtree/blob/master/CHANGELOG.md), suggesting a different version number if necessary.
-- [ ] After merging, tag the commit using these (Mac-compatible) bash commands:
-    ```bash
-    git checkout master
-    git pull
-    sed -n "$(grep -n -m2 '####' CHANGELOG.md | cut -f1 -d: | sed 'N;s/\n/,/')p" CHANGELOG.md | sed '$d'

 After installing NERDTree, the best way to learn it is to turn on the Quick Help. Open NERDTree with the `:NERDTree` command, and press `?` to turn on the Quick Help, which will show you all the mappings and commands available in the NERDTree. Of course, your most complete source of information is the documentation: `:help NERDTree`.

-NERDTree can be extended with custom mappings and functions using its built-in API. The details of this API and are described in the included documentation.

 ### Can NERDTree access remote files via scp or ftp?
 
 Short answer: No, and there are no plans to add that functionality. However, Vim ships with a plugin that does just that. It's called netrw, and by adding the following lines to your `.vimrc`, you can use it to open files over the `scp:`, `ftp:`, or other protocols, while still using NERDTree for all local files. The function seamlessly makes the decision to open NERDTree or netrw, and other supported protocols can be added to the regular expression.
