Synchronize updates in this repository by pulling them from the remote:
``` bash
user@host:~/repo/blocks$ git pull
```
# Pulling from git when your local version has been modified
Here's a typical scenario:
``` console
$git checkout <branch>
(git tells you it won't check out <branch>because you have changes you haven't committed)
```
You now have three choices:
1. Commit the changes to the current branch, because you know you want them
2. Delete the changes by reverting to the previous commit, because you know you don't want them
3. Store the changes locally, because you're not sure if you want them yet
In case 1, you do:
``` console
$git commit -am"<commit message>"
$git push
```
In case 2, you do:
``` console
$git reset --hard HEAD
```
In case 3, you do:
``` console
$git stash
```
After doing any of these three things you should be able to check out the branch you want without any issues.
``` console
$git checkout <branch>
```
**BONUS:** Let's assume you were in case 3 and you stashed the changes, then checked out a working branch. Now you want to switch back to master and get back the changes you made. Here's what you do:
``` console
$git checkout master
$git stash pop
```
