 Done.

+## I want to discard local commits so my branch is the same as one on the server
+
+Confirm that you haven't pushed your changes to the server.
+
+`git status` should show how many commits you are ahead of origin:
+
+```sh
+(bug24)$ git status
+# On branch bug24
+# Your branch is ahead of 'origin/bug24' by 2 commits.
+#   (use "git push" to publish your local commits)
+#
+```
+
+One way of reseting to match origin (to have the same as what is on the remote) is to do this:
+
+```sh
+(master)$ git reset --hard origin/bug24
+```
+
+If you want to only reset to some commit between origin and your local, you can do this: 
+
+```sh
+# one commit
+(bug24)$ git reset --hard HEAD^
+# two commits
+(bug24)$ git reset --hard HEAD^^
+# four commits
+(bug24)$ git reset --hard HEAD~4
+```
+
+<a href="discard-local-uncommited-changes"></a>
+## I want to discard my local, uncommitted changes
+
+```sh
+(master)$ git reset --hard
+# or
+(master)$ git checkout -f
+```
+
+<a href="stage-in-two-commits"></a>
+## I want to add changes in one file to two different commits
+
+`git add` will add the entire file to a commit. `git add -p` will allow to interactively select which changes you want to add.
+
+<a href="remove-from-git"></a>
+## I want to remove a file from git but keep the file
+
+```sh
+(master)$ git rm --cached log.txt
+```
