+
+## Pull Request Guidelines
+
+Don't worry if you get any of the below wrong, or if you don't know how. We'll gladly help out.
+
+### Title
+
+Make sure the title starts with a semantic prefix:
+
+- **feat**: A new feature
+- **fix**: A bug fix
+- **improvement**: An improvement to a current feature
+- **docs**: Documentation only changes
+- **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+- **refactor**: A code change that neither fixes a bug nor adds a feature
+- **perf**: A code change that improves performance
+- **test**: Adding missing tests or correcting existing tests
+- **build**: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
+- **ci**: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
+- **chore**: Other changes that don't modify src or test files
+- **revert**: Reverts a previous commit
+
+### Changelog
+
+Add a brief description of your pull request to the changelog located here: [`src/packages/excalidraw/CHANGELOG.md`](src/packages/excalidraw/CHANGELOG.md)
+
+Notes:
+
+- Make sure to prepend to the section corresponding with the semantic prefix you selected in the title
+- Link to your pull request - this will require updating the CHANGELOG _after_ creating the pull request
+
+### Testing
+
+Once you submit your pull request it will automatically be tested. Be sure to check the results of the test and fix any issues that arise.
+
+It's also a good idea to consider if your change should include additional tests. This is highly recommended for new features or bug-fixes. For example, it's good practice to create a test for each bug you fix which ensures that we don't regress the code in the future.
+
+Finally - always manually test your changes using the convenient staging environment deployed for each pull request. As much as local development attempts to replicate production, there can still be subtle differences in behavior. For larger features consider testing your change in multiple browsers as well.

+
+You can almost do anything with shortcuts. Click on the help icon on the bottom right corner to see them all.

+### Curved lines and arrows
+
+Choose line or arrow and click click click instead of drag.

+### Charts

+You can easily create charts by copy pasting data from Excel or just plain comma separated text.

+### Translating
+
+To translate Excalidraw into other languages, please visit [our Crowdin page](https://crowdin.com/project/excalidraw). To add a new language, [open an issue](https://github.com/excalidraw/excalidraw/issues/new) so we can get things set up on our end first.

+### Create a collaboration session manually
+
+In order to create a session manually you just need to generate a link of this form:
+
+```
+https://excalidraw.com/#room=[0-9a-f]{20},[a-zA-Z0-9_-]{22}
+```
+
+#### Example
+
+```
+https://excalidraw.com/#room=91bd46ae3aa84dff9d20,pfLqgEoY1c2ioq8LmGwsFA
+```
+
+The first set of digits is the room. This is visible from the server that’s going to dispatch messages to everyone that knows this number.
+
+The second set of digits is the encryption key. The Excalidraw server doesn’t know about it. This is what all the participants use to encrypt/decrypt the messages.
