-# conda_remove_env
+# Remove conda environments
 
-Remove one or more conda environments
+Remove multiple conda environments.
 
-1. Clone the repo
+The tool was created to bulk-remove conda environments to avoid the need to have multiple `conda env remove -n NAME` commands. Instead, you can now remove multiple environments with
 
+```text
+python conda_remove_envs.py -n NAME1 NAME2 ...
 ```
+
+## Usage
+
+Remove one environment
+
+```text
+python conda_remove_envs.py -n NAME
+```
+
+Remove multiple environments
+
+```text
+python conda_remove_envs.py -n NAME1 NAME2
+```
+
+## Install
+
+Clone the project
+
+```text
 git clone https://github.com/trevor-moon/conda-remove-envs.git
 ```
 
-2. Run with bash
+Change to the install location
 
+```text
+cd conda-remove-envs
 ```
-bash conda_remove_envs env1 env2
+
+Use
+
+```text
+python conda-remove-envs.py --help
 ```
