+# Import and Convert All Conan C Libraries
+
+Use the [rxsync](https://github.com/goplus/rxsync) tool to convert 1,800 libraries from the [Conan Center Index](https://github.com/conan-io/conan-center-index/tree/master/recipes).
+
+## Steps
+
+1. Use `rxsync` to sync Conan recipes locally
+2. Customize names and generate a name mapping table
+3. Parse dependency information to obtain the conversion list
+4. Perform conversion according to the order in the conversion list
+5. Automatically populate dependencies and remove unnecessary `include`s based on Conan dependency info
+6. After converting each library, submit a pull request. Use GitHub Actions to perform a basic validation via `llgo build`
+7. After merging, tag each `{{clib}}/{{cver}}` folder as `{{clib}}/{{cver}}/v0.1.0` to meet nested module requirements
+
+## Issues
+
+### 1. All `cflags` Included by Default
+
+The automatically generated `llcppg.cfg` includes all header files from dependencies listed under `cflags`. For example, `libxml2` includes header files from `zlib`, and `libxslt` includes headers from both `libxml2` and `zlib` as part of its include paths. This behavior is unintended — for example, in certain cases, headers from `libxml2` and `zlib` need to be removed.
+
+**Preliminary solution:** Automatically remove them during dependency population.
+
+### 2. Local `deps`
+
+How should dependencies be populated for `deps` in `llcppg.cfg`? All batch processing is done locally, while `deps` is expected to reference the GitHub path under `github.com/llpkg`. There's uncertainty about whether locally converted packages can be referenced as dependencies during batch processing.
+
+**Needs verification.**
+
+### 3. Package Order
+
+Sorted by popularity of repository and dependency.
+
+Rule:
+1. Score(Stars/Forks/Watchers/Contributors)
+2. The number of dependency(Less dependency is higher)
+
+Tools: [Rank Tool](https://github.com/MeteorsLiu/reporank)
+
+### 4. Naming Conflicts in Custom Names
+
+Remove `lib` prefix.
+
+However, this may cause naming conflicts and needs to be verified.
+
+### 5. Demo Validation
+
+Batch conversion cannot perform demo validation.
+
+**Preliminary solution:** Use basic `llgo build` validation.
+
+### 6. Trim Prefix
+
+The expected behavior is to configure `trimPrefixes` in `llcppg.cfg` to remove namespaces before committing to the repo.
+However, the automated process may not be able to identify and fill this in automatically.
+
+**No solution yet.**
+
+### 7. Tagging for All Version Branches
+
+How should tags be created?
+
+**Preliminary solution:**
+```
+cjson/3.4.5/v0.1.0
+cjson/3.3.5/v0.1.0
+cjson/3.2.5/v0.1.0
+```
+
+But it's unclear whether Go can recognize this format — needs verification.
+
+### 8. GitHub Action Verification
+
+Is it necessary to add `llcppg`-based validation?
