 ### basic usage:
 
 ```python

-	>>> a = typedlist([
-				myclass(...), 
-				myclass(...),
-				], dtype=myclass)
-	>>> a[0]

+>>> from arrex import *
+>>> a = typedlist([
+			myclass(...), 
+			myclass(...),
+			], dtype=myclass)
+>>> a[0]
+myclass(...)
 ```
 
 in that example, `myclass` can be a primitive numpy type, like `np.float64`
 
 ```python
-	>>> import typedlist.numpy		# this is enabling numpy dtypes for arrex
-	>>> typedlist(dtype=np.float64)
+>>> import typedlist.numpy		# this is enabling numpy dtypes for arrex
+>>> typedlist(dtype=np.float64)
 ```
 
 it can be a more complex type, from module `pyglm` for instance
 
 ```python
-	>>> import typedlist.glm		# this is enabling glm dtypes for arrex
-	>>> typedlist(dtype=glm.vec4)
+>>> import typedlist.glm		# this is enabling glm dtypes for arrex
+>>> typedlist(dtype=glm.vec4)

 ### Use it as a list:
 
 ```python
-	>>> a = typedlist(dtype=vec3)

-	# build from an iterable
-	>>> a = typedlist([], dtype=vec3)
-	
-	# append some data
-	>>> a.append(vec3(1,2,3))

+

+6

 ```
 
 ### Use it as a slice:
 
 ```python
-	>>> myslice = a[:5]		# no data is copied
-	typedlist(....)
+>>> myslice = a[:5]		# no data is copied
+typedlist(....)
 ```
 
 ### Use it as a view on top of a random buffer
 
 ```python
-	>>> a = np.ones((6,3), dtype='f4')
-	>>> myslice = typedlist(a, dtype=vec3)
+>>> a = np.ones((6,3), dtype='f4')
+>>> myslice = typedlist(a, dtype=vec3)
 ```
 
 ### buffer protocol
 
 It does support the buffer protocol, so it can be converted in a great variety of well known arrays, even without any copy
 
 ```python
-	>>> np.array(typedlist([....]))
+>>> np.array(typedlist([....]))
 ```
