 ## How to use
 ```bash
-alias ccc='docker run --rm -it -v ~/.claude:/root/.claude -v ~/.claude.json:/root/.claude.json -v $PWD:$PWD -w $PWD git.shihaam.dev/dockerfiles/ccc'
+alias claude='docker run --rm -it -v ~/.claude:/root/.claude -v ~/.claude.json:/root/.claude.json -v $PWD:$PWD -w $PWD git.shihaam.dev/dockerfiles/ccc'
+```
+
+Args pass straight through:
+
+```bash
+claude              # claude
+claude --resume     # claude --resume
+claude -p "hello"   # claude -p "hello"
+```
+
+For a shell in the container instead, override the entrypoint:
+
+```bash
+docker run --rm -it --entrypoint bash -v ~/.claude:/root/.claude -v ~/.claude.json:/root/.claude.json -v $PWD:$PWD -w $PWD git.shihaam.dev/dockerfiles/ccc
 ```
