 ### How to enable ligatures
 
+You need to explicitly enable ligatures support in following editors:

 - [Jetbrains' products](https://github.com/tonsky/FiraCode/wiki/Intellij-products-instructions) (IntelliJ, etc)

+### Troubleshooting
+
+#### 1. Make sure the font your editor displays is actually Fira Code
+
+Easiest way to do that is to type `@&r` and compare them with the reference image:

+
+#### 2. Make sure you’ve enabled ligatures in your editor
+
+Consult this wiki (see above) for instruction on how to do that.

+Issues: [#291](https://github.com/tonsky/FiraCode/issues/291)
+
+#### 3. Make sure you’re on the latest version of Fira Code
+
+Consult [CHANGELOG](https://github.com/tonsky/FiraCode/blob/master/CHANGELOG.md) to see when it was last updated.
+
+### Known issues
+
+#### Hinting issues
+
+* Uneven spacing in `===` and `!==` at certain font sizes, esp. on Windows [#405](https://github.com/tonsky/FiraCode/issues/405) [#243](https://github.com/tonsky/FiraCode/issues/243) [#119](https://github.com/tonsky/FiraCode/issues/119) [#114](https://github.com/tonsky/FiraCode/issues/114) 
+
+* Different height of `[]` at certain font sizes [#332](https://github.com/tonsky/FiraCode/issues/332) [#251](https://github.com/tonsky/FiraCode/issues/251)
+
+#### Powerline characters are of slightly wrong size
+
+Unfortunately this can’t be fixed for all terminals because they have different ways of calculate font metrics. See [this comment](https://github.com/tonsky/FiraCode/issues/44#issuecomment-187305276)

+
+#### Some ligatures work while some don’t
+
+This is an issue with your editor and how it handles tokenization/syntax highlighting. Nothing can be done in a font to work around that. Report your problem to the corresponding editor’s issue tracker.

+
+#### Anything related to italics
+
+Fira Code does not have italics at all. If you see italicized glyphs it means your editor is “faking” them.
