• [ ] Bugfix
• [ ] Feature
• [ ] Enhancement
• [X ] Other (fixed typos)

Does this PR introduce a breaking change? (check one)

• [ X] No
• [ ] Yes (please describe)

The PR fulfills these requirements:

• [X ] When resolving a specific issue, it's referenced in the PR's title (i.e. [...] (fixes #xxx[,#xxx]), where "xxx" is the issue number)
• [ X] It should address only one issue or feature. If adding multiple features or fixing a bug and adding a new feature, break them into separate PRs if at all possible.

If adding a new feature, or changing the functionality of an existing feature, the PR's description above includes:

• [ ] A convincing reason for adding this feature (to avoid wasting your time, it's best to open a suggestion issue first and wait for approval before working on it)
