 ====== starting a new remote branch ======
-<code>
+In the examples below, there is a shared repo (shared), a user1 (doing the branch changes), and a user2 (needs to pull the branch changes).
-(locally start the new branch)
-git checkout -b new_feature_name
-(push the new local branch to the shared repo)
+Method 1 may be better for you if the branch already exists locally, and you need that history pushed to the shared repo.
-git push origin new_feature_name
-(other people pull changes)
-git pull
-(the new branch is now available, but not being tracked by any local branches)
+===== method 1: start a local branch and push it to the remote =====
+  * shared repo has one branch: master
+  * user1 creates a new local branch called dev<code>
+$ git checkout -b dev
+</code>
+  * push the new local branch to the shared repo:<code>
+$ git push origin dev
+</code>
+  * but wait - even though user1 created the branch and pushed it to the remote, the local branch is not yet tracking the shared branch
+    * option 1 - use %%--set-upstream%%<code>
+git branch --set-upstream dev origin/dev
+(output should be: Branch dev set up to track remote branch dev from origin.)
+</code>
+    * option 2 - delete the local branch and create it again with %%--track%%<code>
+$ git checkout master
+$ git branch -D dev
+$ git checkout --track -b dev origin/dev
+</code>
+    * option 3 - manually edit your .git/config by adding lines similar to the following (this is what %%--set-upstream%% does for you)<code>
+[branch "dev"]
+	remote = origin
+	merge = refs/heads/dev
+</code>
+  * user2 can pull changes to see the new branch, then use the same command as user1 to create a local branch and track the remote branch:<code>
+$ git pull
-(start tracking the remote branch with a new local branch)
+From /path/to/shared/repo
-git checkout --track -b new_branch origin/new_feature_name
+ * [new branch]      dev        -> origin/dev
+Already up-to-date.
+$ git checkout --track -b dev origin/dev
+$ git branch -a
+* dev
+  master
+  remotes/origin/HEAD -> origin/master
+  remotes/origin/dev
+  remotes/origin/master
 </code>
+===== method 2: push a new branch directly to the shared repo =====
+  * shared repo has one branch: master
+  * user1 pushes a new branch (dev) to the shared repo<code>
+$ git push origin origin:refs/heads/dev
+</code>
+  * user1 now has the following branches locally:<code>
+$ git branch -a
+* master
+  remotes/origin/HEAD -> origin/master
+  remotes/origin/dev
+  remotes/origin/master
+</code>
+  * user1 now must create a local branch which is set to "track" the new remote branch:<code>
+$ git checkout --track -b dev origin/dev
+$ git branch -a
+* dev
+  master
+  remotes/origin/HEAD -> origin/master
+  remotes/origin/dev
+  remotes/origin/master
+</code>
+  * user2 can pull changes to see the new branch, then use the same command as user1 to create a local branch and track the remote branch:<code>
+$ git pull
+From /path/to/shared/repo
+ * [new branch]      dev        -> origin/dev
+Already up-to-date.
+$ git checkout --track -b dev origin/dev
+$ git branch -a
+* dev
+  master
+  remotes/origin/HEAD -> origin/master
+  remotes/origin/dev
+  remotes/origin/master
+</code>
+===== Advanced Topics =====
+==== creating a new remote branch from a branch other than master ====
+we want to create a new remote branch called foo2 from an existing remote branch called foo
+<code>
+$ git push origin origin/foo:refs/heads/foo2
+</code>
+==== remove a remote branch ====
+<code>
+git push origin :old_branch_to_be_deleted
+</code>
