 To run Annolid, we suggest using Anaconda package/environment manager for Python. Download and install the [Anaconda](https://www.anaconda.com/products/individual) environment first. Then do the following, using the bash shell in Linux or the conda command line (= Anaconda Prompt) in Windows.
 
-```{note}
-We also provide a pypi version of Annaconda that you can use but it is most likely not an as up-to-date version of the code as the codebase on Github (at least for the foreseable future)

+We also provide a PyPI version of Annolid that you can use, but it may not be as up-to-date as the codebase on GitHub.
 
 ## Requirements
-- Ubuntu / macOS / Windows      \
-- Python >= 3.7                 \
+- Ubuntu / macOS / Windows
+- Python >= 3.10
 - [PyQt4 / PyQt5]
 
 ## Install Annolid locally
 
-We create a virtual environment called _annolid-env_ into which we will install Annolid and all of its dependencies, along with whatever other Python tools we need. Python 3.7 is recommended, as it is the version being used for Annolid development.

 ### Clone Annolid repository and change into the directory
 ```
+conda create -n annolid-env python=3.11
+conda activate annolid-env
+conda install git
+conda install ffmpeg
 git clone --recurse-submodules https://github.com/healthonrails/annolid.git
 cd annolid
+pip install -e .
 ```
-### Installing with Anaconda
-```
-conda env create -f environment.yml

-```{note}
-Note: if you got this error:
-`ERROR: Could not find a version that satisfies the requirement decord>=0.4.0` try to install [ffmpeg](https://ffmpeg.org/) or you can install it in conda with `conda install -c conda-forge ffmpeg` and then install [decord](https://github.com/dmlc/decord) from source.

 ```{note}
-Alternatively you can install with pip if you prefer using
-`pip install -e .`

 We then activate the virtual environment we just created.
 ```
 conda activate annolid-env
 ```
-
 ```{note}
-Be sure to activate the annolid virtual environment every time you restart Anaconda or your computer; the shell prompt should read "(annolid-env)"
