+[color = "#fff6d5"]
+== Group exercise 3
+
+- continuation of the previous 2 phases
+- half of the grade
+- important choices - extend functionality - vs alternative client
+
+
+[background-color = "#124990"]
+[color = "#fff6d5"]
+== Fixing errors with Git
+
+== Typical errors
+
+- staging the wrong files
+- wrong commit messsage
+- committing the wrong file(s)
+- deleting the wrong branch
+- deleting the wrong commit
+- committing sensitive files
+
+== Compounding the gravity
+
+- easier to fix before push
+- more issues with shared commits
+
+== Recommended approaches
+- not pushed
+    ** change history ok
+- pushed
+    ** fix issues and add a new commit
+    ** revert commit with `git revert ...`
+- changing history on pushed commits
+    ** only  if there is no other option
+    ** team is small enough to manage this
+
+
+== Relevant commands
+
+- `git restore --staged <file> ...` - to unstage
+- `git commit --ammend`
+- `git rebase -i HEAD~n`
+- `git revert <sha value>`
+- `git reflog` + `git reset --hard <sha value>` 
+
+
+== Relevant commands - aftermath
+
+- `git push --force-with-lease`  is a safer option that will not overwrite any work on the remote branch if more commits were added to the remote branch
+- `git pull .... --allow-unrelated-histories`

+
+== .gitkeep
+
+- keep in the repository empty folders
+- git keeps track of folders that have files 
+- not really a git special file 
+- widely used convention
+- typically we remove the file when we add other files to the folder 
+
+== .gitattributes
+
+- https://www.git-scm.com/docs/gitattributes
+- control git attributes per path
+- for example configure how EOL is handled
+
+== .gitattributes
+
+```
+# Set the default behavior, in case people don't have core.autocrlf set.
+* text=auto
+
+# Set linux endings for . files
+.bashrc text eol=lf
+.xinitrc text eol=lf
+
+# Explicitly declare text files you want to always be normalized and converted
+# to native line endings on checkout.
+*.c text
+*.h text
+
+# Declare files that will always have CRLF line endings on checkout.
+*.sln text eol=crlf
+
+# Denote all files that are truly binary and should not be modified.
+*.png binary
+*.jpg binary
+
