 - Adds the **r2ai** command to the radare2 shell: `r2 -qc r2ai`
 - You can also run the wrapper in $PATH: `r2pm -r r2ai`
 
-Drop your API keys in environment variables or files in your home:
+Drop your API keys in environment variables or use the configuration file:
 
 ```console
-$ cat ~/.r2ai.anthropic-key

 ## Saving settings
 
 You may customize and save your configuration settings using your OS's default settings file (e.g `~/.radare2rc` on Linux).
 For example, the following configuration sets Claude 3.7 by default, with max output tokens to 64000.
 
+
+```console
+$ r2ai -E
 ```
+
+then you can type the commands you want to run when the r2ai plugin is loaded:
+
+```console
 r2ai -e api=anthropic
 r2ai -e model=claude-3-7-sonnet-20250219
 r2ai -e max_tokens=64000

+
+Decai is the radare2 plugin for decompiling functions with the help of language models.
+
+By default uses a local ollama server, but can you can pick any other service by using 'decai -e api=?'.
+
+[0x00000000]> decai -e api=?
+r2ai deepseek anthropic gemini hf mistral ollama openapi openai vllm xai
+
+## Using Ollama
+
+* Visit https://ollama.com to install it.
+* Download the model of choice: 'ollama run llama3.3'
+* Configure decai to use the given model with: 'decai -e model=?'
+
+These are the most recommended models for decompiling in local:
+
+* hhao/qwen2.5-coder-tools:latest (18GB of ram)
+* hhao/qwen2.5-coder-tools:32b (24GB of ram required)
+
+## Common Options
+* 'decai -e baseurl=<url>' override default host and port for API endpoint (e.g., 'http://localhost:11434')
+
+* 'decai -e deterministic=true' to remove randomness from decompilation responses
+* 'decai -e lang=Python' to output the decompilation in Python instead of C
+* 'decai -e hlang=Catalan' to add comments or explanations in that language (instead of English)
+* 'decai -e cmds=pdd,pdg' use r2dec and r2ghidra instead of r2's pdc as input for decompiling
+* 'decai -e prompt=..' default prompt must be fine for most models and binaries, feel free to tweak it
+
+## API Keys
+
+Remove services like OpenAI, Mistral, Anthropic, Grok, Gemini, .. require API keys to work.
+
+See 'decai -k' to list the status of available APIkeys
+
+Decai will pick them from the environment or the config files in your home:
+
+* echo KEY > ~/.r2ai.openai-key
+* export OPENAI_API_KEY=...
+
+## Using the R2AI Server:
+
+Install r2ai or r2ai-server with r2pm:
+
+[0x0000000]> decai -e api=r2ai
+[0x0000000]> r2pm -ci r2ai
+
+Choose one of the recommended models (after r2pm -r r2ai):
+
+* -m ibm-granite/granite-20b-code-instruct-8k-GGUF
+* -m QuantFactory/granite-8b-code-instruct-4k-GGUF
+* -m TheBloke/Mistral-7B-Instruct-v0.2-GGUF
+
+Start the webserver:
+
+$ r2pm -r r2ai-server -l r2ai -m granite-8...
+`,
+  auto: `# Radare2 Auto Mode
+
+Use function calling to execute radare2 commands in order to resolve the user request defined in the "User Prompt" section, analyze the responses attached in the "Command Results" section.
+
+## Function Calling
+
+Respond ONLY using plain JSON. Process user query and decide which function calls are necessary to solve the task.
+
+1. Analyze the user request to determine if we need to run commands to extend the knowledge and context of the problem.
+2. If function call is needed, construct the JSON like this:
+ - Fill the "action" key with the "r2cmd" value.
+ - Specify the "command" as a string.
+ - Optionally, provide a "reason" and "description"
+3. If the answer can be provided and no more function calls are required:
+ - Use the key "action": "reply".
+ - Include "response" with the direct answer to the user query.
+
+Return the result as a JSON object.
+
+### Sample Function Calling Communication
+
+Command Results: already performed actions with their responses
+User Prompt: "Count how many functions we have here."
+Response:
+{
+    "action": "r2cmd",
+    "command": "aflc",
+    "description": "Count functions"
+    "reason": "Evaluate if the program is analyzed before running aaa"
+}
+
+## Rules
+
+Use radare2 to resolve user requests.
+
+* Explain each step in the "reason" field of the JSON.
+* Follow the initial analysis instructions.
+* Output only valid JSON as specified.
+* Decompile and inspect functions, starting from main.
+* Run only the needed commands to gather info.
+* Use "@ (address|symbol)" to seek temporarily.
+* Output should be a verbose markdown report.
+* Use "sym." or "fcn." prefixes if "pdc" is empty.
+* If a seek fails, use "f~name" to find the symbol's address.
+
+### Initial Analysis
+
+1. Run "aflc" to count the number of functions
+2. If the output of "aflc" is "0" run "aaa" once, then "aflc" again
+3. Run only one command at a time (do not use ";")
+
+### Special cases
+
+* On Swift binaries run...

+	"- Formulate a plan. Think step by step. Analyze the binary as much as possible before answering.\n"
+	"- You must keep going until you have a final answer.\n"
+	"- Double check that final answer. Make sure you didn't miss anything.\n"
+	"- Make sure you call tools and functions correctly.\n"
