+## Understanding hooks
+
+A hook is basically code that runs as a result of some event. In git we have
+client-side hooks and server-side hooks. Client-side git hooks run on your
+machine when perform actions on your local git repo. `pre-commit` is a
+client-side hook that runs before you commit something, you can use this hook
+to check for what is being commited and run tests for example to check if the
+formating of the code conforms to a style guide. `post-merge` runs after a
+successful merge takes place. `commit-msg` - This hook is invoked on `git
+commit` and gets the name of the file that holds the commit message. Checks can
+be performed on the commit message to see whether or not it conforms to a
+standard format. If the hook exits with a non-zero cdoe, the commit is aborted.
+
+We also have server-side hooks that live on the remote's bare repository.
+`pre-recieve` hook runs before refs are updated on the remote. The script can
+exit with a non-zero code and the push won't be accepted and the client will be
+notified. `post-recieve` on the other hand runs when all the refs are updated
+on the remote. This hook can be thought of as a hook that runs when there is a
+'push'. This hook gets information of what refs were updated - if the master
+branch was updated then this information is passed on to the script along with
+the last hash and the new updated hash.
