-All the commits in this repo are done with OpenCommit — look into [the commits](https://github.com/di-sukharev/opencommit/commit/eae7618d575ee8d2e9fff5de56da79d40c4bc5fc) to see how OpenCommit works. Emoji and long commit description text is configurable.
+All the commits in this repo are authored by OpenCommit — look at [the commits](https://github.com/di-sukharev/opencommit/commit/eae7618d575ee8d2e9fff5de56da79d40c4bc5fc) to see how OpenCommit works. Emojis and long commit descriptions are configurable, basically everything is.
 
-## Setup
+## Setup OpenCommit as a CLI tool
 
-> The minimum supported version of Node.js is the latest v14. Check your Node.js version with `node --version`.
+You can use OpenCommit by simply running it via the CLI like this `oco`. 2 seconds and your staged changes are committed with a meaningful message.
 
-1. Install opencommit globally to use in any repository:
+1. Install OpenCommit globally to use in any repository:
 
    ```sh
    npm install -g opencommit
    ```
 
-2. Get your API key from [OpenAI](https://platform.openai.com/account/api-keys)
+2. Get your API key from [OpenAI](https://platform.openai.com/account/api-keys) or other supported LLM providers (we support them all). Make sure that you add your OpenAI payment details to your account, so the API works.
 
-3. Set the key to opencommit config:
+3. Set the key to OpenCommit config:
 
    ```sh
-   opencommit config set OPENAI_API_KEY=<your token>
+   oco config set OCO_API_KEY=<your_api_key>
    ```
 
-   Your token isn't sent to anyone, it's saved in `~/.opencommit` config file.
+   Your API key is stored locally in the `~/.opencommit` config file.
 
 ## Usage
 
-You can call `opencommit` directly to generate a commit message for your staged changes:
+You can call OpenCommit with `oco` command to generate a commit message for your staged changes:
 
 ```sh
 git add <files...>
-opencommit
+oco
 ```
 
-You can also use the `oc` shortcut:
+Running `git add` is optional, `oco` will do it for you.
+
+### Running locally with Ollama
+
+You can also run it with local model through ollama:
+
+- install and start ollama
+- run `ollama run mistral` (do this only once, to pull model)
+- run (in your project directory):
 
 ```sh
 git add <files...>
-oc
+oco config set OCO_AI_PROVIDER='ollama' OCO_MODEL='llama3:8b'
 ```
 
-## Features
+Default model is `mistral`.
 
-### Preface commits with emoji 🤠
+If you have ollama that is set up in docker/ on another machine with GPUs (not locally), you can change the default endpoint url.
 
-[GitMoji](https://gitmoji.dev/) convention is used.
-
-To add emoji:
+You can do so by setting the `OCO_API_URL` environment variable as follows:
 
 ```sh
-oc config set emoji=true
+oco config set OCO_API_URL='http://192.168.1.10:11434/api/chat'
 ```
 
-To remove emoji:
+where 192.168.1.10 is example of endpoint URL, where you have ollama set up.
+
+#### Troubleshooting Ollama IPv6/IPv4 Connection Fix
+
+If you encounter issues with Ollama, such as the error
 
 ```sh
-oc config set emoji=false
+✖ local model issues. details: connect ECONNREFUSED ::1:11434
 ```
 
-### Postface commits with descriptions of changes
+It's likely because Ollama is not listening on IPv6 by default. To fix this, you can set the OLLAMA_HOST environment variable to 0.0.0.0 before starting Ollama:
 
-To add descriptions:
+```bash
+export OLLAMA_HOST=0.0.0.0
+```
+
+This will make Ollama listen on all interfaces, including IPv6 and IPv4, resolving the connection issue. You can add this line to your shell configuration file (like `.bashrc` or `.zshrc`) to make it persistent across sessions.
+
+### Flags
+
+There are multiple optional flags that can be used with the `oco` command:
+
+#### Use Full GitMoji Specification
+
+Link to the GitMoji specification: https://gitmoji.dev/
+
+This flag can only be used if the `OCO_EMOJI` configuration item is set to `true`. This flag allows users to use all emojis in the GitMoji specification, By default, the GitMoji full specification is set to `false`, which only includes 10 emojis (🐛✨📝🚀✅♻️⬆️🔧🌐💡).
+
+This is due to limit the number of tokens sent in each request. However, if you would like to use the full GitMoji specification, you can use the `--fgm` flag.
+
+```
+oco --fgm
+```
+
+#### Skip Commit Confirmation
+
+This flag allows users to automatically commit the changes without having to manually confirm the commit message. This is useful for users who want to streamline the commit process and avoid additional steps. To use this flag, you can run the following command:
+
+```
+oco --yes
+```
+
+## Configuration
+
+### Local per repo configuration
+
+Create a `.env` file and add OpenCommit config variables there like this:
+
+```env
+...
+OCO_AI_PROVIDER=<openai (default), anthropic, azure, ollama, gemini, flowise, deepseek, aimlapi>
+OCO_API_KEY=<your OpenAI API token> // or other LLM provider API token
+OCO_API_URL=<may be used to set proxy path to OpenAI api>
+OCO_API_CUSTOM_HEADERS=<JSON string of custom HTTP headers to include in API requests>
+OCO_TOKENS_MAX_INPUT=<max model token limit (default: 4096)>
+OCO_TOKENS_MAX_OUTPUT=<max response tokens (default: 500)>
+OCO_DESCRIPTION=<postface a message with ~3 sentences description of the changes>
+OCO_EMOJI=<boolean, add GitMoji>
+OCO_MODEL=<either 'gpt-4o-mini' (default), 'gpt-4o', 'gpt-4', 'gpt-4-turbo', 'gpt-3.5-turbo', 'gpt-3.5-turbo-0125', 'gpt-4-1106-preview', 'gpt-4-turbo-preview' or 'gpt-4-0125-preview' or any Anthropic or Ollama model or any string basically, but it should be a valid model name>
+OCO_LANGUAGE=<locale, scroll to the bottom to see options>
+OCO_MESSAGE_TEMPLATE_PLACEHOLDER=<message template placeholder, default: '$msg'>
+OCO_PROMPT_MODULE=<either conventional-commit or @commitlint, default: conventional-commit>
+OCO_ONE_LINE_COMMIT=<one line commit message, default: false>
+```
+
+Global configs are same as local configs, but they are stored in the global `~/.opencommit` config file and set with `oco config set` command, e.g. `oco config set OCO_MODEL=gpt-4o`.
+
+### Global config for all repos
+
+Local config still has more priority than Global config, but you may set `OCO_MODEL` and `OCO_LOCALE` globally and set local configs for `OCO_EMOJI` and `OCO_DESCRIPTION` per repo which is more convenient.
+
+Simply set any of the variables above like this:
 
 ```sh
-oc config set description=true
+oco config set OCO_MODEL=gpt-4o-mini
 ```
 
-To remove description:
+To see all available configuration parameters and their accepted values:
 
 ```sh
-oc config set description=false
+oco config describe
 ```
 
-## Git hook
+To see details for a specific parameter:
 
-You can set opencommit as Git [`prepare-commit-msg`](https://git-scm.com/docs/githooks#_prepare_commit_msg) hook. Hook integrates with you IDE Source Control and allows you edit the message before commit.
+```sh
+oco config describe OCO_MODEL
+```
+
+Configure [GitMoji](https://gitmoji.dev/) to preface a message.
+
+```sh
+oco config set OCO_EMOJI=true
+```
+
+To remove preface emojis:
+
+```sh
+oco config set OCO_EMOJI=false
+```
+
+Other config options are behaving the same.
+
+### Output WHY the changes were done (WIP)
+
+You can set the `OCO_WHY` config to `true` to have OpenCommit output a short description of WHY the changes were done after the commit message. Default is `false`.
+
+To make this perform accurate we must store 'what files do' in some kind of an index or embedding and perform a lookup (kinda RAG) for the accurate git commit message. If you feel like building this comment on this ticket https://github.com/di-sukharev/opencommit/issues/398 and let's go from there together.
+
+```sh
+oco config set OCO_WHY=true
+```
+
+### Switch to GPT-4 or other models
+
+By default, OpenCommit uses `gpt-4o-mini` model.
+
+You may switch to gpt-4o which performs better, but costs more 🤠
+
+```sh
+oco config set OCO_MODEL=gpt-4o
+```
+
+or for as a cheaper option:
+
+```sh
+oco config set OCO_MODEL=gpt-3.5-turbo
+```
+
+### Switch to other LLM providers with a custom URL
+
+By default OpenCommit uses [OpenAI](https://openai.com).
+
+You could switch to [Azure OpenAI Service](https://learn.microsoft.com/azure/cognitive-services/openai/) or Flowise or Ollama.
+
+```sh
+oco config set OCO_AI_PROVIDER=azure OCO_API_KEY=<your_azure_api_key> OCO_API_URL=<your_azure_endpoint>
+
+oco config set OCO_AI_PROVIDER=flowise OCO_API_KEY=<your_flowise_api_key> OCO_API_URL=<your_flowise_endpoint>
+
+oco config set OCO_AI_PROVIDER=ollama OCO_API_KEY=<your_ollama_api_key> OCO_API_URL=<your_ollama_endpoint>
+```
+
+### Locale configuration
+
+To globally specify the language used to generate commit messages:
+
+```sh
+# de, German, Deutsch
+oco config set OCO_LANGUAGE=de
+oco config set OCO_LANGUAGE=German
+oco config set OCO_LANGUAGE=Deutsch
+
+# fr, French, française
+oco config set OCO_LANGUAGE=fr
+oco config set OCO_LANGUAGE=French
+oco config set OCO_LANGUAGE=française
+```
+
+The default language setting is **English**
+All available languages are currently listed in the [i18n](https://github.com/di-sukharev/opencommit/tree/master/src/i18n) folder
+
+### Push to git (gonna be deprecated)
+
+A prompt for pushing to git is on by default but if you would like to turn it off just use:
+
+```sh
+oco config set OCO_GITPUSH=false
+```
+
+and it will exit right after commit is confirmed without asking if you would like to push to remote.
+
+### Switch to `@commitlint`
+
+OpenCommit allows you to choose the prompt module used to generate commit messages. By default, OpenCommit uses its conventional-commit message generator. However, you can switch to using the `@commitlint` prompt module if you prefer. This option lets you generate commit messages in respect with the local config.
+
+You can set this option by running the following command:
+
+```sh
+oco config set OCO_PROMPT_MODULE=<module>
+```
+
+Replace `<module>` with either `conventional-commit` or `@commitlint`.
+
+#### Example:
+
+To switch to using the `'@commitlint` prompt module, run:
+
+```sh
+oco config set OCO_PROMPT_MODULE=@commitlint
+```
+
+To switch back to the default conventional-commit message generator, run:
+
+```sh
+oco config set OCO_PROMPT_MODULE=conventional-commit
+```
+
+#### Integrating with `@commitlint`
+
+The integration between `@commitlint` and OpenCommit is done automatically the first time OpenCommit is run with `OCO_PROMPT_MODULE` set to `@commitlint`. However, if you need to force set or reset the configuration for `@commitlint`, you can run the following command:
+
+```sh
+oco commitlint force
+```
+
+To view the generated configuration for `@commitlint`, you can use this command:
+
+```sh
+oco commitlint get
+```
+
+This allows you to ensure that the configuration is set up as desired.
+
+Additionally, the integration creates a file named `.opencommit-commitlint` which contains the prompts used for the local `@commitlint` configuration. You can modify this file to fine-tune the example commit message generated by OpenAI. This gives you the flexibility to make adjustments based on your preferences or project guidelines.
+
+OpenCommit generates a file named `.opencommit-commitlint` in your project directory which contains the prompts used for the local `@commitlint` configuration. You can modify this file to fine-tune the example commit message generated by OpenAI. If the local `@commitlint` configuration changes, this file will be updated the next time OpenCommit is run.
+
+This offers you greater control over the generated commit messages, allowing for customization that aligns with your project's conventions.
+
+## Git flags
+
+The `opencommit` or `oco` commands can be used in place of the `git commit -m "${generatedMessage}"` command. This means that any regular flags that are used with the `git commit` command will also be applied when using `opencommit` or `oco`.
+
+```sh
+oco --no-verify
+```
+
+is translated to :
+
+```sh
+git commit -m "${generatedMessage}" --no-verify
+```
+
+To include a message in the generated message, you can utilize the template function, for instance:
+
+```sh
+oco '#205: $msg’
+```
+
+> opencommit examines placeholders in the parameters, allowing you to append additional information before and after the placeholders, such as the relevant Issue or Pull Request. Similarly, you have the option to customize the OCO_MESSAGE_TEMPLATE_PLACEHOLDER configuration item, for example, simplifying it to $m!"
+
+### Message Template Placeholder Config
+
+#### Overview
+
+The `OCO_MESSAGE_TEMPLATE_PLACEHOLDER` feature in the `opencommit` tool allows users to embed a custom message within the generated commit message using a template function. This configuration is designed to enhance the flexibility and customizability of commit messages, making it easier for users to include relevant information directly within their commits.
+
+#### Implementation Details
+
+In our codebase, the implementation of this feature can be found in the following segment:
+
+```javascript
+commitMessage = messageTemplate.replace(
+  config.OCO_MESSAGE_TEMPLATE_PLACEHOLDER,
+  commitMessage
+);
+```
+
+This line is responsible for replacing the placeholder in the `messageTemplate` with the actual `commitMessage`.
+
+#### Usage
+
+For instance, using the command `oco '$msg #205’`, users can leverage this feature. The provided code represents the backend mechanics of such commands, ensuring that the placeholder is replaced with the appropriate commit message.
+
+#### Committing with the Message
+
+Once users have generated their desired commit message, they can proceed to commit using the generated message. By understanding the feature's full potential and its implementation details, users can confidently use the generated messages for their commits.
+
+### Ignore files
+
+You can remove files from being sent to OpenAI by creating a `.opencommitignore` file. For example:
+
+```ignorelang
+path/to/large-asset.zip
+**/*.jpg
+```
+
+This helps prevent opencommit from uploading artifacts and large files.
+
+By default, opencommit ignores files matching: `*-lock.*` and `*.lock`
+
+## Git hook (KILLER FEATURE)
+
+You can set OpenCommit as Git [`prepare-commit-msg`](https://git-scm.com/docs/githooks#_prepare_commit_msg) hook. Hook integrates with your IDE Source Control and allows you to edit the message before committing.
 
 To set the hook:
 
 ```sh
-oc hook set

 To unset the hook:

+## Setup OpenCommit as a GitHub Action (BETA) 🔥
+
+OpenCommit is now available as a GitHub Action which automatically improves all new commits messages when you push to remote!
+
+This is great if you want to make sure all commits in all of your repository branches are meaningful and not lame like `fix1` or `done2`.
+
+Create a file `.github/workflows/opencommit.yml` with the contents below:
+
+```yml
+name: 'OpenCommit Action'
+
+on:
+  push:
+    # this list of branches is often enough,
+    # but you may still ignore other public branches
+    branches-ignore: [main master dev development release]
+
+jobs:
+  opencommit:
+    timeout-minutes: 10
+    name: OpenCommit
+    runs-on: ubuntu-latest
+    permissions: write-all
+    steps:
+      - name: Setup Node.js Environment
+        uses: actions/setup-node@v2
+        with:
+          node-version: '16'
+      - uses: actions/checkout@v3
+        with:
+          fetch-depth: 0
+      - uses: di-sukharev/opencommit@github-action-v1.0.4
+        with:
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+
+        env:
+          # set openAI api key in repo actions secrets,
+          # for openAI keys go to: https://platform.openai.com/account/api-keys
+          # for repo secret go to: <your_repo_url>/settings/secrets/actions
+          OCO_API_KEY: ${{ secrets.OCO_API_KEY }}
+
+          # customization
+          OCO_TOKENS_MAX_INPUT: 4096
+          OCO_TOKENS_MAX_OUTPUT: 500
+          OCO_OPENAI_BASE_PATH: ''
+          OCO_DESCRIPTION: false
+          OCO_EMOJI: false
+          OCO_MODEL: gpt-4o
+          OCO_LANGUAGE: en
+          OCO_PROMPT_MODULE: conventional-commit
+```
+
+That is it. Now when you push to any branch in your repo — all NEW commits are being improved by your never-tired AI.
+
+Make sure you exclude public collaboration branches (`main`, `dev`, `etc`) in `branches-ignore`, so OpenCommit does not rebase commits there while improving the messages.
+
+Interactive rebase (`rebase -i`) changes commits' SHA, so the commit history in remote becomes different from your local branch history. This is okay if you work on the branch alone, but may be inconvenient for other collaborators.
+
 ## Payments
 
-You pay for your own requests to OpenAI API. OpenCommit uses ChatGPT official model, that is ~10x times cheaper than GPT-3.
+You pay for your requests to OpenAI API on your own.

+Commit Message Conventions:
+- The commit message consists of three parts: Header, Body, and Footer.

+- The JSON output should contain the commit messages for a bug fix and a new feature in the following format:
+\`\`\`json
+{
+  "localLanguage": "${translation.localLanguage}",
+  "commitFix": "<Header of commit for bug fix with scope>",
+  "commitFeat": "<Header of commit for feature with scope>",
+  "commitFixOmitScope": "<Header of commit for bug fix without scope>",
+  "commitFeatOmitScope": "<Header of commit for feature without scope>",
+  "commitDescription": "<Description of commit for both the bug fix and the feature>"
+}
+\`\`\`
+- The "commitDescription" should not include the commit message's header, only the description.
+- Description should not be more than 74 characters.
+
+Additional Details:
+- Changing the variable 'port' to uppercase 'PORT' is considered a bug fix.
+- Allowing the server to listen on a port specified through the environment variable is considered a new feature.
