 ##### Advanced Inputs/Parameters
 - ExifTool Path: Optionally provide an updated/custom version of exiftool.  If not provided the default version is included in the tool.
 - Calibration ID: For Sentera sensors, calibration images are tagged with "CAL".  Optionally provide a different tag if the image names have been modified.  For non-Sentera sensors all images are scanned for calibration panels.
-- Use all panel sets(6X):  By default only the best calibration set will be used to perform corrections for Sentera sensors.  Select this option to perform corrections using all available calibration panel captures.
+- Use All Panel Sets(6X):  By default only the best calibration set will be used to perform corrections for Sentera sensors.  Select this option to perform corrections using all available calibration panel captures.
 - Delete/Overwrite Original Images: Select this option and set the input and output paths to match to overwrite the original images with the corrected images. Not reccomended as original images cannot be restored.
-- Output as uint16(0-65535):  By default corrected images are formated in Float32 with values in reflectance ranging from 0-1.  Selecting this option will output the corrected images in Uint16 with values ranging from 0-65535.  This may be required for certain photogrametry software and corrected images will have a much smaller file size.
+- Output as UInt16(0-65535):  By default corrected images are formated in Float32 with values in reflectance ranging from 0-1.

+## Installation instructions for usage/development in Python
+
+#### Windows (Conda)
+    
+1) Download [Miniconda](https://docs.conda.io/en/latest/miniconda.html) for Python3.7
+
+2) Open Anaconda Prompt and clone **py-radiometric-corrections** with
+
+        >> git clone https://github.com/SenteraLLC/py-radiometric-corrections.git
+
+3) Open Anaconda Prompt and navigate to **py-radiometric-corrections/**.  Run:
+
+        >> conda env create -f environment.yml
+        >> conda activate imgcorrect-venv
+        >> pip install .
+        
+4) This creates an *imgcorrect-venv* environment that all scripts should be run in and installs the **analyticstest**
+   library for the scripts to reference. 
+        
+If no errors appear, the **imgcorrect** library should be installed correctly.
+
+### Usage
+The imagery correction in this repository can be used via:
+* Importing the various library functions defined in the package
+* Running the pre-defined scripts with a Python installation of version 3.6 or above
+* Running the standalone executable on the command line
+
+Open Anaconda Prompt and navigate to **py-radiometric-corrections/**.  Run:
+
+        >> conda activate imgcorrect-venv
+Get a list of required arguments:	
+
+	>> python scripts\correct_images.py -h 
+Run corrections: 
+
+	>> python scripts\correct_images.py "input_path" -o "output_path" **Additional optional commands
+
+
+Optional commands:
+
+  --calibration_id "CALIBRATION_ID", -c CALIBRATION_ID
+  * Identifier in the name of the image that denotes it is from the calibration set. If not specified, defaults to "CAL".
+  
+  --output_path OUTPUT_PATH, -o OUTPUT_PATH
+  * Path to output folder at which the corrected images will be stored. If not supplied, corrected images will be placed into the input directory.
+  
+  --no_ils_correct, -i 
+  * If selected, ILS correction will not be applied to the images.
+  
+  --no_reflectance_correct, -r
+  * If selected, reflectance correction will not be applied to the images.
+
+  --all_panels, -a
+  * If selected, reflectance correction will be applied using all panel images.
+
+  --delete_original, -d
+  * Overwrite original 12-bit images with the corrected versions. If selected, corrected images are renamed to their original names. If not, an extension is added.
+  
+  --exiftool_path EXIFTOOL_PATH, -e EXIFTOOL_PATH
+  * Path to ExifTool executable. ExifTool is required for the conversion; if not passed, the script will use a bundled ExifTool executable.
+  
+  --uint16_output, -u   
+  * If selected, scale of output values will be adjusted to 0-65535 and dtype will be changed to uint16.
