@@ -6,22 +6,26 @@ We're currently recruiting for a team of 5 core maintainers.
 As a core maintainer you will have a strong say in the direction of the project. Big changes will require a majority of maintainers to agree.
 
 ## Code of conduct
+
 First and foremost, you'll be evaluated against [these core values](https://github.com/PyTorchLightning/pytorch-lightning/blob/master/.github/CONTRIBUTING.md). Any code we commit or feature we add needs to align with those core values.
 
 ## The bar for joining the team
+
 Lightning is being used to solve really hard problems at the top AI labs in the world. As such, the bar for adding team members is extremely high. Candidates must have solid engineering skills, have a good eye for user experience, and must be a power user of Lightning and PyTorch.
 
 With that said, the Lightning team will be diverse and a reflection of an inclusive AI community. You don't have to be an engineer to contribute! Scientists with great usability intuition and PyTorch ninja skills are welcomed!
 
 ## Responsibilities:
+
 The responsibilities mainly revolve around 3 things.
 
 ### Github issues
+
 - Here we want to help users have an amazing experience. These range from questions from new people getting into DL to questions from researchers about doing something esoteric with Lightning
-Often, these issues require some sort of bug fix, document clarification or new functionality to be scoped out.

+  otherwise we'll do a few more until we're both comfortable :)
 
 ### Project directions
+
 There are some big decisions which the project must make. For these I expect core contributors to have something meaningful to add if it’s their area of expertise.
 
 ### Diversity
+
 Lightning should reflect the broader community it serves. As such we should have scientists/researchers from
 different fields contributing!
 
 The first 5 core contributors will fit this profile. Thus if you overlap strongly with experiences and expertise as someone else on the team, you might have to wait until the next set of contributors are added.
 
 ### Summary: Requirements to apply
+
 The goal is to be inline with expectations for solving issues by the last one so you can do them on your own. If not, I might ask you to solve a few more specific ones.

 #### How to fix PR with mixed base and target branches?
 
 Sometimes you start your PR as a bug-fix but it turns out to be more of a feature (or the other way around).
 Do not panic, the solution is very straightforward and quite simple.
 All you need to do are these two steps in arbitrary order:
-   - Ask someone from Core to change the base/target branch to the correct one
-   - Rebase or cherry-pick your commits onto the correct base branch...
+
+- Ask someone from Core to change the base/target branch to the correct one
+- Rebase or cherry-pick your commits onto the correct base branch...
 
 Let's show how to deal with the git...
 the sample case is moving a PR from `master` to `release/1.2-dev` assuming my branch name is `my-branch`
 and the last true master commit is `ccc111` and your first commit is `mmm222`.
-   * **Cherry-picking** way
-     ```bash
-     git checkout my-branch
-     # create a local backup of your branch
-     git checkout -b my-branch-backup
-     # reset your branch to the correct base
-     git reset release/1.2-dev --hard
-     # ACTION: this step is much easier to do with IDE
-     #  so open one and cherry-pick your last commits from `my-branch-backup`
-     #  resolve all eventual conflict as the new base may contain different code
-     # when all done, push back to the open PR
-     git push -f
-     ```
-   * **Rebasing way**, see more about [rebase onto usage](https://womanonrails.com/git-rebase-onto)
-     ```bash
-     git checkout my-branch
-     # rebase your commits on the correct branch
-     git rebase --onto release/1.2-dev ccc111
-     # if there is no collision you shall see just success
-     #  eventually you would need to resolve collision and in such case follow the instruction in terminal
-     # when all done, push back to the open PR
-     git push -f
-     ```
