+# Getting started
+
+Let's assume that both Python and Julia are installed.
+
+## Installation
+
+It is recommended to use [conda](https://conda.io/projects/conda/en/latest/user-guide/getting-started.html) virtul environment.
+
+## Using Julia Awkward Arrays from Python
+
+ - To install [Awkward Array](https://github.com/scikit-hep/awkward) Python package:
+
+```python
+conda install -c conda-forge awkward
+```
+ - To install [JuliaCall](https://juliapy.github.io/PythonCall.jl):
+
+```python
+conda install pyjuliacall
+```
+JuliaCall takes care of installing all necessary Julia packages, including this package. 
+
+```python
+import awkward as ak
+from juliacall import Main as jl
+
+jl.seval("using AwkwardArray")
+```
+
+## Using Python Awkward Arrays from Julia
+
+[PythonCall](https://github.com/JuliaPy/PythonCall.jl) is currently configured to use the Julia-specific Python distribution
+installed by the [CondaPkg.jl](https://github.com/JuliaPy/CondaPkg.jl) package.
+
+```julia
+using CondaPkg
+CondaPkg.add("awkward")
+```
+
+```julia
+using PythonCall
+
+const ak = pyimport("awkward")
+
+println(ak.__version__)
+2.6.4
+```
+
+See [Examples](@ref).
