 # Salesforce Metadata Git Merge Driver
+
+A custom Git merge driver designed specifically for Salesforce metadata files. This tool helps resolve merge conflicts in Salesforce XML metadata files by understanding their structure and intelligently merging changes.
+
+## Features
+
+- Intelligent merging of Salesforce XML metadata files
+- Handles complex metadata structures like arrays with unique identifiers
+- Supports both local and global installation
+- Easy to use with SFDX CLI plugin commands
+
+## Installation
+
+### As SFDX Plugin
+
+```bash
+sf plugins install sf-git-merge-driver
+```
+
+### Local Repository Installation
+
+```bash
+sf git merge driver install
+```
+
+This will:
+- Configure your Git settings to use the merge driver
+- Add appropriate entries to your `.gitattributes` file
+- Set up the driver to handle XML files
+
+## Uninstallation
+
+```bash
+sf git merge driver uninstall
+```
+
+## How It Works
+
+The merge driver works by:
+1. Converting XML to JSON for easier processing
+2. Using a specialized three-way merge algorithm that understands Salesforce metadata structures
+3. Intelligently resolving conflicts based on metadata type
+4. Converting the merged result back to properly formatted XML
+
+## Configuration
+
+The driver is configured to work with `.xml` files by default. The installation adds the following to your `.gitattributes` file:
+
+```
+*.xml merge=salesforce-source
+```
+
+## Changelog
+
+[changelog.md](CHANGELOG.md) is available for consultation.
+
+## Versioning
+
+Versioning follows [SemVer](http://semver.org/) specification.

 ## Installation
 
-### As SFDX Plugin
-
 ```bash
 sf plugins install sf-git-merge-driver
 ```
 
-### Local Repository Installation

+## `sf git merge driver install`
+
+Installs a local git merge driver for the given org and branch.
 
-```bash
-sf git merge driver install
 ```
+USAGE
+  $ sf git merge driver install [--json] [--flags-dir <value>]
 
-This will:
-- Configure your Git settings to use the merge driver
-- Add appropriate entries to your `.gitattributes` file
-- Set up the driver to handle XML files
+GLOBAL FLAGS

-## Uninstallation
+DESCRIPTION
+  Installs a local git merge driver for the given org and branch.
 
-```bash
-sf git merge driver uninstall
+  Installs a local git merge driver for the given org and branch, by updating the `.gitattributes` files in the project,
+  creating a new merge driver configuration in the `.git/config` of the project, and installing the binary in the
+  node_modules/.bin directory.
+
+EXAMPLES
+  Install the driver for a given project:
+
+    $ sf git merge driver install

+## `sf git merge driver run`
+
+Runs the merge driver for the specified files.

+USAGE
+  $ sf git merge driver run -a <value> -o <value> -t <value> -p <value> [--json] [--flags-dir <value>]
+
+FLAGS
+  -a, --ancestor-file=<value>  (required) path to the common ancestor version of the file
+  -o, --our-file=<value>       (required) path to our version of the file
+  -p, --output-file=<value>    (required) path to the file where the merged content will be written
+  -t, --theirs-file=<value>    (required) path to their version of the file
+
+GLOBAL FLAGS
+  --flags-dir=<value>  Import flag values from a directory.
+  --json               Format output as json.
+
+DESCRIPTION
+  Runs the merge driver for the specified files.
+
+  Runs the merge driver for the specified files, handling the merge conflict resolution using Salesforce-specific merge
+  strategies. This command is typically called automatically by Git when a merge conflict is detected.
+
+EXAMPLES
+  Run the merge driver for conflicting files:
+
+    $ sf git merge driver run --ancestor-file=<value> --our-file=<value> --theirs-file=<value> --output-file=<value>
+
+  Where:
+  - ancestor-file is the path to the common ancestor version of the file
+  - our-file is the path to our version of the file
+  - their-file is the path to their version of the file
+  - output-file is the path to the file where the merged content will be written
+```

+DESCRIPTION
+  Runs the merge driver for the specified files.
+
+  Runs the merge driver for the specified files, handling the merge conflict resolution using Salesforce-specific merge
+  strategies. This command is typically called automatically by Git when a merge conflict is detected.
+
+EXAMPLES
+  Run the merge driver for conflicting files:
+
+    $ sf git merge driver run --ancestor-file=<value> --our-file=<value> --theirs-file=<value> --output-file=<value>
+
+  Where:
+  - ancestor-file is the path to the common ancestor version of the file
+  - our-file is the path to our version of the file
+  - their-file is the path to their version of the file
+  - output-file is the path to the file where the merged content will be written

-USAGE
-  $ sf git merge driver run -a <value> -o <value> -t <value> -p <value> [--json] [--flags-dir <value>]
-
-FLAGS
-  -a, --ancestor-file=<value>  (required) path to the common ancestor version of the file
-  -o, --our-file=<value>       (required) path to our version of the file
-  -p, --output-file=<value>    (required) path to the file where the merged content will be written
-  -t, --theirs-file=<value>    (required) path to their version of the file
-
-GLOBAL FLAGS
-  --flags-dir=<value>  Import flag values from a directory.
-  --json               Format output as json.
-
-DESCRIPTION
-  Runs the merge driver for the specified files.
-
-  Runs the merge driver for the specified files, handling the merge conflict resolution using Salesforce-specific merge
-  strategies. This command is typically called automatically by Git when a merge conflict is detected.
-
-EXAMPLES
-  Run the merge driver for conflicting files:
-
-    $ sf git merge driver run --ancestor-file=<value> --our-file=<value> --theirs-file=<value> --output-file=<value>
-
-  Where:
-  - ancestor-file is the path to the common ancestor version of the file
-  - our-file is the path to our version of the file
-  - their-file is the path to their version of the file
-  - output-file is the path to the file where the merged content will be written

-  Uninstalls the local git merge driver for the given org and branch.
-
-  Uninstalls the local git merge driver for the given org and branch, by removing the merge driver content in the
