+## Strings
+
+Strings are small pieces of text that we can use in our programs. We can
+create strings by simply writing some text in quotes.
+
+```python
+>>> 'hello'
+'hello'
+>>> 'this is a test'
+'this is a test'
+>>> 
+```
+
+String's can also be written using "double quotes" instead of 'single quotes'.
+This is useful when the string needs to contain single quotes.
+
+```python
+>>> "hello there"
+'hello there'
+>>> "it's sunny"
+"it's sunny"
+>>> 
+```
+
+It's also possible to add single quotes and double quotes into the same
+string, but most of the time we don't need to do that so I'm not going
+to talk about it now.
+
+It doesn't matter which quotes you use when the string doesn't need to
+contain any quotes. If you think that one of the quote types looks nicer
+than the other or you find it faster to type, go ahead and use that.
+
+Strings can be joined together easily with `+` or repeated with `*`:
+
+```python
+>>> "hello" + "world"
+'helloworld'
+>>> "hello" * 3
+'hellohellohello'
+>>> 
+```
+
+Note that a `#` inside a string doesn't create a comment.
+
+```python
+>>> "strings can contain # characters"
+'strings can contain # characters'
+>>> 
+```
