 ## Configuration
 
-The different tools and sub-tools used by CodiumAI pr-agent are easily configurable via the configuration file: `/pr-agent/settings/configuration.toml`.
+The different tools and sub-tools used by CodiumAI PR-Agent are adjustable via the **[configuration file](pr_agent/settings/configuration.toml)**
-##### Git Provider:
-You can select your git_provider with the flag `git_provider` in the `config` section
 
-##### PR Reviewer:
+### Working from CLI
+When running from source (CLI), your local configuration file will be initially used.
+
+Example for invoking the 'review' tools via the CLI: 
 
-You can enable/disable the different PR Reviewer abilities with the following flags (`pr_reviewer` section):
 ```
-require_focused_review=true
+python cli.py --pr-url=<pr_url>  review
-require_score_review=true
-require_tests_review=true
-require_security_review=true
 ```
-You can contol the number of suggestions returned by the PR Reviewer with the following flag:
+In addition to general configurations, the 'review' tool will use parameters from the `[pr_reviewer]` section (every tool has a dedicated section in the configuration file).
-```inline_code_comments=3```
+
-And enable/disable the inline code suggestions with the following flag:
+Note that you can print results locally, without publishing them, by setting in `configuration.toml`:
-```inline_code_comments=true```
+
+```
+[config]
+publish_output=true
+verbosity_level=2
+```
+This is useful for debugging or experimenting with the different tools.
+
+### Working from pre-built repo (GitHub Action/GitHub App/Docker)
+When running PR-Agent from a pre-built repo, the default configuration file will be loaded.
+
+To edit the configuration, you have two options: 
+1. Place a local configuration file in the root of your local repo. The local file will be used instead of the default one.
+2. For online usage, just add `--config_path=<value>` to you command, to edit a specific configuration value.
+For example if you want to edit `pr_reviewer` configurations, you can run:
+```
+/review --pr_reviewer.extra_instructions="..." --pr_reviewer.require_score_review=false ...
+```
+
+Any configuration value in `configuration.toml` file can be similarly edited.
+
+### General configuration parameters
+
+#### Changing a model
+See [here](pr_agent/algo/__init__.py) for the list of available models.
+
+To use Llama2 model, for example, set:
+```
+[config]
+model = "replicate/llama-2-70b-chat:2c1608e18606fad2812020dc541930f2d0495ce32eee50074220b87300bc16e1"
+[replicate]
+key = ...
+```
+(you can obtain a Llama2 key from [here](https://replicate.com/replicate/llama-2-70b-chat/api))
+
+Also review the [AiHandler](pr_agent/algo/ai_handler.py) file for instruction how to set keys for other models.
+
+#### Extra instructions
+All PR-Agent tools have a parameter called `extra_instructions`, that enables to add free-text extra instructions. Example usage:
+```
+/update_changelog --pr_update_changelog.extra_instructions="Make sure to update also the version ..."
+```

 - [Method 5: Run as a GitHub App](INSTALL.md#method-5-run-as-a-github-app)
   - Allowing you to automate the review process on your private or public repositories
 
-## Usage and Tools
-
-**PR-Agent** provides five types of interactions ("tools"): `"PR Reviewer"`, `"PR Q&A"`, `"PR Description"`, `"PR Code Sueggestions"` and `"PR Reflect and Review"`.
-
-- The "PR Reviewer" tool automatically analyzes PRs, and provides various types of feedback.
-- The "PR Q&A" tool answers free-text questions about the PR.
-- The "PR Description" tool automatically sets the PR Title and body.
-- The "PR Code Suggestion" tool provide inline code suggestions for the PR that can be applied and committed.
-- The "PR Reflect and Review" tool initiates a dialog with the user, asks them to reflect on the PR, and then provides a more focused review.
 
 ## How it works
 
+The following diagram illustrates PR-Agent tools and their flow:
+
 ![PR-Agent Tools](https://www.codium.ai/wp-content/uploads/2023/07/codiumai-diagram-v4.jpg)
 
 Check out the [PR Compression strategy](./PR_COMPRESSION.md) page for more details on how we convert a code diff to a manageable LLM prompt
 
+## Why use PR-Agent?
+
+A reasonable question that can be asked is: `"Why use PR-Agent? What make it stand out from existing tools?"`
+
+Here are some advantages of PR-Agent:
+
+- We emphasize **real-life practical usage**. Each tool (review, improve, ask, ...) has a single GPT-4 call, no more. We feel that this is critical for realistic team usage - obtaining an answer quickly (~30 seconds) and affordably.
+- Our [PR Compression strategy](./PR_COMPRESSION.md)  is a core ability that enables to effectively tackle both short and long PRs.
+- Our JSON prompting strategy enables to have **modular, customizable tools**. For example, the '/review' tool categories can be controlled via the [configuration](./CONFIGURATION.md) file. Adding additional categories is easy and accessible.
+- We support **multiple git providers** (GitHub, Gitlab, Bitbucket), **multiple ways** to use the tool (CLI, GitHub Action, GitHub App, Docker, ...), and **multiple models** (GPT-4, GPT-3.5, Anthropic, Cohere, Llama2).
+- We are open-source, and welcome contributions from the community.
+
+
 ## Roadmap
 
-- [ ] Support open-source models, as a replacement for OpenAI models. (Note - a minimal requirement for each open-source model is to have 8k+ context, and good support for generating JSON as an output)
+- [x] Support additional models, as a replacement for OpenAI (see [here](https://github.com/Codium-ai/pr-agent/pull/172))
-- [x] Support other Git providers, such as Gitlab and Bitbucket.
+- [ ] Develop additional logic for handling large PRs
-- [ ] Develop additional logic for handling large PRs, and compressing git patches
 - [ ] Add additional context to the prompt. For example, repo (or relevant files) summarization, with tools such a [ctags](https://github.com/universal-ctags/ctags)
 - [ ] Adding more tools. Possible directions:
   - [x] PR description
   - [x] Inline code suggestions
   - [x] Reflect and review
+  - [x] Rank the PR (see [here](https://github.com/Codium-ai/pr-agent/pull/89))   
   - [ ] Enforcing CONTRIBUTING.md guidelines
   - [ ] Performance (are there any performance issues)
   - [ ] Documentation (is the PR properly documented)
-  - [ ] Rank the PR importance
   - [ ] ...
