-### Anaconda
+## Conda (Miniconda or Anaconda)
 
-Freqtrade can also be installed using Anaconda (or Miniconda).
+Freqtrade can also be installed with Miniconda or Anaconda.
+Conda is a package manager and virtual environment manager in one.
+The purpose of installing Conda (Miniconda or Anaconda) is to automatically prepare and manage the extensive library dependencies of the Freqtrade program.
 
-!!! Note
-    This requires the [ta-lib](#1-install-ta-lib) C-library to be installed first. See below.
+You can start with any clean distribution of Debian-based Linux distributions, which includes Ubuntu Linux.
+For other popular Linux distributions, see: https://distrowatch.com/ or https://www.ubuntupit.com/best-debian-based-linux-distributions/
+
+Installation requirement: Your Linux is a Debian based distribution with bash terminal
+
+To get know more about Conda check : https://linuxnetmag.com/miniconda-vs-anaconda/
+
+Shortly : Conda < Miniconda < Anaconda
+
+https://www.dunderdata.com/blog/anaconda-is-bloated-set-up-a-lean-robust-data-science-environment-with-miniconda-and-conda-forge
+
+The difference lies in the number of packages that need to be installed upfront: how heavy/light the installation is. Difference is like ~1:8. It is recommended to install Miniconda instead of Anaconda.
+
+#### 1. Instal Conda
+
+##### Download conda file:
+
+installation file of chosen distribution you can find here
+
+https://docs.conda.io/en/latest/miniconda.html
+
+##### Verify file integrity with SHA256 checksum:
+
+official SHA256 checksum can be found here
+
+https://docs.conda.io/en/latest/miniconda_hashes.html
+
+Navigate to the directory with your file, and run SHA256 checksum of your file, check with following command
 
 ```bash
-conda env create -f environment.yml
+sha256sum ./Miniconda3-number-of-the-package
 ```
 
+both checksum suppose to match
+
+##### Install conda:
+
+While in directory with your file, install conda
+
+```bash
+bash ./Miniconda3-number-of-the-package
+```
+
+Confirm with yes all questions
+
+After installation, it is mandatory to turn your terminal OFF and ON again.
+
+CTRL + D (close terminal), CTRL + ALT + T (open terminal)
+
+#### 2. Prepare Conda environment
+
+
+enter the conda base environment:
+
+```bash
+conda activate base
+```
+
+If you want, you can prevent the (base) conda environment from being activated automatically as well.
+
+```bash
+conda config --set auto_activate_base false
+```
+
+
+##### Change the channels with upgrades:
+
+Conda as a package manager can download new packages from "channels". The best developed Conda channel, is not the default channel and is called `conda-forge`. The code below switches to it.
+
+```bash    
+# adding forge
+conda config --env --add channels conda-forge
+
+# make it strict
+conda config --env --set channel_priority strict 	
+```
+
+You can check the status of conda with the following code.
+
+```bash
+conda info
+conda config --show channels
+conda config --show channel_priority
+```
+
+#### 3. Freqtrade Conda Environment
+
+Now you have conda, but only base environment,
+
+```bash# download freqtrade
+conda env list
+```
+
+It is time to setup environment of the Freqtrade itself:
+
+
+Conda `create` command, installs all nested dependencies, for the selected libraries automatically
+
+general structure of installation command is:
+
+```bash
+conda create -n [name of the environment] [python version] [packages]
+```
+
+so it can be
+
+```bash
+conda create -n freqtrade-conda python=3.8 pandas numpy ta-lib git wheel virtualenv
+```
+
+or if you expect, to use later jupiter for [data-analysis](data-analysis.md), use
+
+```bash
+conda create -n freqtrade-jupyter-conda python=3.8 pandas numpy ta-lib git wheel virtualenv jupyter
+```
+
+the same works for [docker](docker.md), for spyder and other useful programs.

+
+!!! NOTE:
+It may happen that creating a new Conda environment, populated with selected packages at the moment of creation, takes less time than installing a large, heavy dependent package into the old environment,

+
+##### Enter/exit freqtrade-conda venv:
+
+to enter choosen conda environment
+
+```bash
+conda activate freqtrade-conda
+
+```
+
+to exit conda environment
+
+```bash
+conda deactivate						
+```
+
+#### 4. Freqtrade Instalation
+
+Within the newly created freqtrade-conda environment, download and install Freqtrade. To process --install command, may take a few minutes
+
+```bash
+# download freqtrade
+git clone https://github.com/freqtrade/freqtrade.git
+
+# enter downloaded directory 'freqtrade'
+cd freqtrade      
+
+# run setup
+./setup.sh --install                                        
+```
+
+Create virtual environment (yes, python3-venv environment, inside conda-environment), where Freqtrade program can run.
+
+Running python3-venv seems to be requirement of the Freqtrade program itself.
+
+```bash
+# create venv environment, inside hidden directory /freqtrede/.env
+python3 -m venv ./.env/
+
+# run the python3-venv environment
+source ./.env/bin/activate
+
+# install last required package            
+pip install -e .						
+```
+
+##### pip install within conda, a reminder:
+
+The documentation of conda says that pip should NOT be used within conda, because internal problems can occur.
+However, they are rare
+
+That is, why the conda-forge channel is preferred: (and if no library is available in conda, you have to use pip)
+
+* more libraries are available (less need for pip)
+* conda-forge works better with pip
+* the libraries are newer
+
+
+#### 5. You are ready
+
+You are ready to run, create the user directory and configuration file, run the program dry to verify that everything is working, and run a backtest to double check.
+
+```bash
+freqtrade create-userdir --userdir user_data
+freqtrade new-config --config config.json
+freqtrade download-data -t 5m 15m 1h --days 100
+freqtrade trade --strategy SampleStrategy  
+freqtrade backtesting -s SampleStrategy
+```
+
+important shortcuts
+
+```bash
+# activate base environment
+conda activate
+
+# activate freqtrade-conda environment
+conda activate freqtrade-conda
+
+#deactivate any conda environments
+conda deactivate
+
+# list installed conda environments
+conda env list
+
+# activation/deactivate the venv
+source ./.env/bin/activate
+deactivate                                      
+```
+
+Happy trading!
