-## Development Workflow

-Start by forking the Minio GitHub repository, make changes in a branch and then send a pull request. We encourage pull requests to discuss code changes. Here are the steps in details:
+If you do not have a working Golang environment setup please follow [Golang Installation Guide](https://docs.minio.io/docs/how-to-install-golang).
 
 ### Setup your Minio Github Repository

+...
+Checking dependencies for Minio.. Done
+Installed govet
+Building Libraries

-### Create your feature branch
-Before making code changes, make sure you create a separate branch for these changes
+###  Developer Guidelines
+``Minio`` community welcomes your contribution. To make the process as seamless as possible, we ask for the following:
+* Go ahead and fork the project and make your changes. We encourage pull requests to discuss code changes.
+    - Fork it
+    - Create your feature branch (git checkout -b my-new-feature)
+    - Commit your changes (git commit -am 'Add some feature')
+    - Push to the branch (git push origin my-new-feature)
+    - Create new Pull Request
 
-```
-$ git checkout -b my-new-feature
-```
+* If you have additional dependencies for ``Minio``, ``Minio`` manages its dependencies using [govendor](https://github.com/kardianos/govendor)
+    - Run `go get foo/bar`
+    - Edit your code to import foo/bar
+    - Run `make pkg-add PKG=foo/bar` from top-level directory
 
-### Test Minio server changes
-After your code changes, make sure
+* If you have dependencies for ``Minio`` which needs to be removed
+    - Edit your code to not import foo/bar
+    - Run `make pkg-remove PKG=foo/bar` from top-level directory
 
-- To add test cases for the new code. If you have questions about how to do it, please ask on our [Slack](slack.minio.io) channel.
-- To run `make verifiers`
-- To squash your commits into a single commit. `git rebase -i`. It's okay to force update your pull request.
-- To run `go test -race ./...` and `go build` completes.
+* When you're ready to create a pull request, be sure to:
+    - Have test cases for the new code. If you have questions about how to do it, please ask in your pull request.
+    - Run `make verifiers`
+    - Squash your commits into a single commit. `git rebase -i`. It's okay to force update your pull request.
+    - Make sure `go test -race ./...` and `go build` completes.
 
-### Commit changes
-After verification, commit your changes. This is a [great post](https://chris.beams.io/posts/git-commit/) on how to write useful commit messages
-
-```
-$ git commit -am 'Add some feature'
-```
-
-### Push to the branch
-Push your locally committed changes to the remote origin (your fork)
-```
-$ git push origin my-new-feature
-```
-
-### Create a Pull Request
-Pull requests can be created via GitHub. Refer to [this document](https://help.github.com/articles/creating-a-pull-request/) for detailed steps on how to create a pull request. After a Pull Request gets peer reviewed and approved, it will be merged.
-
-## FAQs
-### How does ``Minio`` manages dependencies? 
-``Minio`` manages its dependencies using [govendor](https://github.com/kardianos/govendor). To add a dependency
-- Run `go get foo/bar`
-- Edit your code to import foo/bar
-- Run `make pkg-add PKG=foo/bar` from top-level directory
-
-To remove a dependency
-- Edit your code to not import foo/bar
-- Run `make pkg-remove PKG=foo/bar` from top-level directory
-
-### What are the coding guidelines for Minio?
-``Minio`` is fully conformant with Golang style. Refer: [Effective Go](https://github.com/golang/go/wiki/CodeReviewComments) article from Golang project. If you observe offending code, please feel free to send a pull request or ping us on [Slack](slack.minio.io).
