-which has to be updated every time dependencies change.

 conan profile show
 ```
 
-#### Custom profile
+If the default profile is not suitable for your environment, you can create a custom profile and pass it to Conan.
+More information on customizing Conan can be found in the [Advanced Conan configuration](./docs/build/advanced_conan.md).
 
-If the default profile does not work for you and you do not yet have a Conan
-profile, you can create one by running:
+#### Add xrplf remote
+
+Run the following command to add the `xrplf` remote, which hosts some of our dependencies:
 
 ```bash
-conan profile detect
-```
-
-You may need to make changes to the profile to suit your environment. You can
-refer to the provided `conan/profiles/default` profile for inspiration, and you
-may also need to apply the required [tweaks](#conan-profile-tweaks) to this
-default profile.
-
-### Patched recipes
-
-Occasionally, we need patched recipes or recipes not present in Conan Center.
-We maintain a fork of the Conan Center Index
-[here](https://github.com/XRPLF/conan-center-index/) containing the modified and newly added recipes.
-
-To ensure our patched recipes are used, you must add our Conan remote at a
-higher index than the default Conan Center remote, so it is consulted first. You
-can do this by running:
-
-```bash
-conan remote add --index 0 xrplf https://conan.ripplex.io
-```
-
-Alternatively, you can pull our recipes from the repository and export them locally:
-
-```bash
-# Define which recipes to export.
-recipes=('abseil' 'ed25519' 'mpt-crypto' 'openssl' 'secp256k1' 'snappy' 'soci' 'wasm-xrplf' 'wasmi')
-
-# Selectively check out the recipes from our CCI fork.
-cd external
-mkdir -p conan-center-index
-cd conan-center-index
-git init
-git remote add origin git@github.com:XRPLF/conan-center-index.git
-git sparse-checkout init
-for recipe in "${recipes[@]}"; do
-    echo "Checking out recipe '${recipe}'..."
-    git sparse-checkout add recipes/${recipe}
-done
-git fetch origin master
-git checkout master
-
-./export_all.sh
-cd ../../
-```
-
-In the case we switch to a newer version of a dependency that still requires a
-patch or add a new dependency, it will be necessary for you to pull in the changes and re-export the
-updated dependencies with the newer version. However, if we switch to a newer
-version that no longer requires a patch, no action is required on your part, as
-the new recipe will be automatically pulled from the official Conan Center.
-
-> [!NOTE]
-> You might need to add `--lockfile=""` to your `conan install` command
-> to avoid automatic use of the existing `conan.lock` file when you run
-> `conan export` manually on your machine
->
-> This is not recommended though, as you might end up using different revisions of recipes.

-### Conan profile tweaks
-
-#### Missing compiler version
-
-If you see an error similar to the following after running `conan profile show`:
-
-```text
-ERROR: Invalid setting '17' is not a valid 'settings.compiler.version' value.
-Possible values are ['5.0', '5.1', '6.0', '6.1', '7.0', '7.3', '8.0', '8.1',
-'9.0', '9.1', '10.0', '11.0', '12.0', '13', '13.0', '13.1', '14', '14.0', '15',
-'15.0', '16', '16.0']
-Read "http://docs.conan.io/2/knowledge/faq.html#error-invalid-setting"
-```
-
-you need to add your compiler to the list of compiler versions in
-`$(conan config home)/settings_user.yml`, by adding the required version number(s)
-to the `version` array specific for your compiler. For example:
-
-```yaml
-compiler:
-  apple-clang:
-    version: ["17.0"]
-```
-
-#### Multiple compilers
-
-If you have multiple compilers installed, make sure to select the one to use in
-your default Conan configuration **before** running `conan profile detect`, by
-setting the `CC` and `CXX` environment variables.
-
-For example, if you are running MacOS and have [homebrew
-LLVM@18](https://formulae.brew.sh/formula/llvm@18), and want to use it as a
-compiler in the new Conan profile:
-
-```bash
-export CC=$(brew --prefix llvm@18)/bin/clang
-export CXX=$(brew --prefix llvm@18)/bin/clang++
-conan profile detect
-```
-
-You should also explicitly set the path to the compiler in the profile file,
-which helps to avoid errors when `CC` and/or `CXX` are set and disagree with the
-selected Conan profile. For example:
-
-```text
-[conf]
-tools.build:compiler_executables={'c':'/usr/bin/gcc','cpp':'/usr/bin/g++'}
-```
-
-#### Multiple profiles
-
-You can manage multiple Conan profiles in the directory
-`$(conan config home)/profiles`, for example renaming `default` to a different
-name and then creating a new `default` profile for a different compiler.
-
-#### Select language
-
-The default profile created by Conan will typically select different C++ dialect
-than C++20 used by this project. You should set `20` in the profile line
-starting with `compiler.cppstd=`. For example:
-
-```bash
-sed -i.bak -e 's|^compiler\.cppstd=.*$|compiler.cppstd=20|' $(conan config home)/profiles/default
-```
-
-#### Select standard library in Linux
-
-**Linux** developers will commonly have a default Conan [profile][] that
-compiles with GCC and links with libstdc++. If you are linking with libstdc++
-(see profile setting `compiler.libcxx`), then you will need to choose the
-`libstdc++11` ABI:
-
-```bash
-sed -i.bak -e 's|^compiler\.libcxx=.*$|compiler.libcxx=libstdc++11|' $(conan config home)/profiles/default
-```
-
-#### Select architecture and runtime in Windows
-
-**Windows** developers may need to use the x64 native build tools. An easy way
-to do that is to run the shortcut "x64 Native Tools Command Prompt" for the
-version of Visual Studio that you have installed.
-
-Windows developers must also build `xrpld` and its dependencies for the x64
-architecture:
-
-```bash
-sed -i.bak -e 's|^arch=.*$|arch=x86_64|' $(conan config home)/profiles/default
-```
-
-**Windows** developers also must select static runtime:
-
-```bash
-sed -i.bak -e 's|^compiler\.runtime=.*$|compiler.runtime=static|' $(conan config home)/profiles/default
-```
-
-#### Clang workaround for grpc
-
-If your compiler is clang, version 19 or later, or apple-clang, version 17 or
-later, you may encounter a compilation error while building the `grpc`
-dependency:
-
-```text
-In file included from .../lib/promise/try_seq.h:26:
-.../lib/promise/detail/basic_seq.h:499:38: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw]
-  499 |                     Traits::template CallSeqFactory(f_, *cur_, std::move(arg)));
-      |                                      ^
-```
-
-The workaround for this error is to add two lines to profile:
-

+[Unity builds][unity-build] may be faster for the first build (at the cost of much more
 memory) since they concatenate sources into fewer translation units. Non-unity
 builds may be faster for incremental builds, and can be helpful for detecting
 `#include` omissions.
 
+### Verifying headers
+
+The regular build only compiles `.cpp` files, so a header is only ever checked
+through whatever translation unit happens to include it. A header that forgets
+an `#include` is not caught as long as every `.cpp` that uses it includes its
+missing dependency first. The `verify_headers` option (ON by default) adds a
+`verify-headers` target that compiles every header on its own, which fails if a
+header is not self-contained:
+
+```bash
+cmake --build . --target verify-headers
+```
+
+The per-header objects are excluded from the `all` target, so a normal build
+never compiles them; they are built only through `verify-headers`. The generated
+translation units do appear in `compile_commands.json`, so clang-tidy (and
+clangd and IDEs) can lint each header on its own. Pass `-Dverify_headers=OFF` to
+omit them entirely.

-2. Modify [`conanfile.py`](./conanfile.py):
-   - Add a version of the package to the `requires` property.
-   - Change any default options for the package by adding them to the
-     `default_options` property (with syntax `'$package:$option': $value`).
-3. Modify [`CMakeLists.txt`](./CMakeLists.txt):
-   - Add a call to `find_package($package REQUIRED)`.
-   - Link a library from the package to the target `xrpl_libs`
-     (search for the existing call to `target_link_libraries(xrpl_libs INTERFACE ...)`).
-4. Start coding! Don't forget to include whatever headers you need from the package.

+Reduce run-clang-tidy output to its unique errors.

+It does two things:
+
+  1. Filters the raw output down to diagnostics and their source-context lines
+     (the indented "  103 | ..." / "      | ^" lines clang-tidy prints),
+     matching the "path:line:col: error:" diagnostic shape.
+
+  2. Deduplicates. The same diagnostic in a header is reported once per
+     translation unit that includes it, so identical error blocks are collapsed
+     to their first occurrence.
+
+An "error block" is an "error:" line together with the indented context lines
+and any "note:" lines that follow it (up to the next "error:" line). Blocks are
+compared as a whole, so an error stays attached to its own context, and
+first-occurrence order is preserved.
+
+The deduplicated output goes to stdout; a summary of unique error counts per
+check is printed to stderr.

+The set of files is chosen by pre-commit (see .pre-commit-config.yaml), which
+filters to C/C++ sources and excludes `.ipp` fragments. Headers are linted
+directly: the `verify_headers` build option (ON by default) compiles every
+`.h`/`.hpp` on its own, so each header is the main file of its own
+compile_commands.json entry and run-clang-tidy can analyse it just like a

+# Advanced Conan configuration
+
+This document provides advanced instructions for setting up and configuring Conan for `xrpld` development: custom profiles, the lockfile, patched recipes, and profile tweaks.
+
+## Custom profile
+
+If the default profile does not work for you and you do not yet have a Conan
+profile, you can create one by running:
+
+```bash
+conan profile detect
+```
+
+You may need to make changes to the profile to suit your environment. You can
+refer to the provided `conan/profiles/default` profile for inspiration, and you
+may also need to apply the required [tweaks](#conan-profile-tweaks) to this
+default profile.
+
+## Conan lockfile
+
+To achieve reproducible dependencies, we use a [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html),
+which has to be updated every time dependencies change.
+
+Please see the [instructions on how to regenerate the lockfile](../../conan/lockfile/README.md).
+
+## Patched recipes
+
+Occasionally, we need patched recipes or recipes not present in Conan Center.
+We maintain a fork of the Conan Center Index
+[here](https://github.com/XRPLF/conan-center-index/) containing the modified and newly added recipes.
+
+To ensure our patched recipes are used, you must add our Conan remote at a
+higher index than the default Conan Center remote, so it is consulted first. You
+can do this by running:
+
+```bash
+conan remote add --index 0 --force xrplf https://conan.xrplf.org/repository/conan/
+```
+
+Alternatively, you can pull our recipes from the repository and export them locally:
+
+```bash
+# Define which recipes to export.
+recipes=('abseil' 'ed25519' 'mpt-crypto' 'openssl' 'secp256k1' 'snappy' 'soci' 'wasm-xrplf' 'wasmi')
+
+# Selectively check out the recipes from our CCI fork.
+cd external
+mkdir -p conan-center-index
+cd conan-center-index
+git init
+git remote add origin git@github.com:XRPLF/conan-center-index.git
+git sparse-checkout init
+for recipe in "${recipes[@]}"; do
+    echo "Checking out recipe '${recipe}'..."
+    git sparse-checkout add recipes/${recipe}
+done
+git fetch origin master
+git checkout master
+
+./export_all.sh
+cd ../../
+```
+
+In the case we switch to a newer version of a dependency that still requires a
+patch or add a new dependency, it will be necessary for you to pull in the changes and re-export the
+updated dependencies with the newer version. However, if we switch to a newer
+version that no longer requires a patch, no action is required on your part, as
+the new recipe will be automatically pulled from the official Conan Center.
+
+> [!NOTE]
+> You might need to add `--lockfile=""` to your `conan install` command
+> to avoid automatic use of the existing `conan.lock` file when you run
+> `conan export` manually on your machine
+>
+> This is not recommended though, as you might end up using different revisions of recipes.
+
+## Conan profile tweaks
+
+### Missing compiler version
+
+If you see an error similar to the following after running `conan profile show`:
+
+```text
+ERROR: Invalid setting '17' is not a valid 'settings.compiler.version' value.
+Possible values are ['5.0', '5.1', '6.0', '6.1', '7.0', '7.3', '8.0', '8.1',
+'9.0', '9.1', '10.0', '11.0', '12.0', '13', '13.0', '13.1', '14', '14.0', '15',
+'15.0', '16', '16.0']
+Read "http://docs.conan.io/2/knowledge/faq.html#error-invalid-setting"
+```
+
+you need to create `$(conan config home)/settings_user.yml` file if it doesn't exist and add the required version number(s)
+to the `version` array specific for your compiler. For example:
+
+```yaml
+compiler:
+  apple-clang:
+    version: ["17.0"]
+```
+
+### Multiple compilers
+
+If you have multiple compilers installed, make sure to select the one to use in
+your default Conan configuration **before** running `conan profile detect`, by
+setting the `CC` and `CXX` environment variables.
+
+For example, if you are running MacOS and have [homebrew
+LLVM@18](https://formulae.brew.sh/formula/llvm@18), and want to use it as a
+compiler in the new Conan profile:
+
+```bash
+export CC=$(brew --prefix llvm@18)/bin/clang
+export CXX=$(brew --prefix llvm@18)/bin/clang++
+conan profile detect
+```
+
+You should also explicitly set the path to the compiler in the profile file,
+which helps to avoid errors when `CC` and/or `CXX` are set and disagree with the
+selected Conan profile. For example:
+
+```text
+[conf]
+tools.build:compiler_executables={'c':'/usr/bin/gcc','cpp':'/usr/bin/g++'}
+```
+
+### Multiple profiles
+
+You can manage multiple Conan profiles in the directory
+`$(conan config home)/profiles`, for example renaming `default` to a different
+name and then creating a new `default` profile for a different compiler.
+
+### Select language
+
+The default profile created by Conan will typically select different C++ dialect
+than C++23 used by this project. You should set `23` in the profile line
+starting with `compiler.cppstd=`. For example:
+
+```bash
+sed -i.bak -e 's|^compiler\.cppstd=.*$|compiler.cppstd=23|' $(conan config home)/profiles/default
+```
+
+### Select standard library in Linux
+
+**Linux** developers will commonly have a default Conan [profile][] that
+compiles with GCC and links with libstdc++. If you are linking with libstdc++
+(see profile setting `compiler.libcxx`), then you will need to choose the
+`libstdc++11` ABI:
+
+```bash
+sed -i.bak -e 's|^compiler\.libcxx=.*$|compiler.libcxx=libstdc++11|' $(conan config home)/profiles/default
+```
+
+### Select architecture and runtime in Windows
+
+**Windows** developers may need to use the x64 native build tools. An easy way
+to do that is to run the shortcut "x64 Native Tools Command Prompt" for the
+version of Visual Studio that you have installed.
+
+Windows developers must also build `xrpld` and its dependencies for the x64
+architecture:
+
+```bash
+sed -i.bak -e 's|^arch=.*$|arch=x86_64|' $(conan config home)/profiles/default
+```
+
+**Windows** developers also must select static runtime:
+
+```bash
+sed -i.bak -e 's|^compiler\.runtime=.*$|compiler.runtime=static|' $(conan config home)/profiles/default
+```
+
+## Add a Dependency
+
+If you want to experiment with a new package, follow these steps:
+
+1. Search for the package on [Conan Center](https://conan.io/center/).
+2. Modify [`conanfile.py`](../../conanfile.py):
+   - Add a version of the package to the `requires` property.
+   - Change any default options for the package by adding them to the
+     `default_options` property (with syntax `'$package:$option': $value`).
+3. Regenerate the [Conan lockfile](../../conan/lockfile/README.md) so the new
+   dependency is captured:
+
+   ```bash
+   ./conan/lockfile/regenerate.sh
+   ```
+
+4. Modify [`CMakeLists.txt`](../../CMakeLists.txt):
+   - Add a call to `find_package($package REQUIRED)`.
+   - Link a library from the package to the target `xrpl_libs`
+     (search for the existing call to `target_link_libraries(xrpl_libs INTERFACE ...)`).
+5. Start coding! Don't forget to include whatever headers you need from the package.

+Older compilers may fail to build the latest `develop` code: the codebase now

+If the latest code doesn't build for you, update your build toolchain first.
+
+## Linux and macOS
+
+The **recommended way** to get a development environment on Linux and macOS is
+the Nix development shell. It provides the exact tooling used in CI — `git`,
+`python`, `conan`, `cmake`, `clang-tidy`, `clang-format`, and everything else —
+with a single command and without installing anything system-wide:
+
+```bash
+nix --experimental-features 'nix-command flakes' develop
 ```
 
-If you use different Linux distribution, hope the instruction above can guide
-you in the right direction. We try to maintain compatibility with all recent
-compiler releases, so if you use a rolling distribution like e.g. Arch or CentOS
-then there is a chance that everything will "just work".
+On **Linux**, Nix also provides the compiler (GCC). On **macOS**, the shell uses
+your **system-wide Apple Clang** as the compiler, so you still need to manage
+its version (see below).
 
-## macOS
+See [Using the Nix development shell](./nix.md) for installation and usage
+details, including how to select a different compiler.
 
-Open a Terminal and enter the below command to bring up a dialog to install
-the command line developer tools.
-Once it is finished, this command should return a version greater than the
-minimum required (see [BUILD.md][]).
+> [!NOTE]
+> Using Nix is not mandatory. Any custom environment (Homebrew packages or
+> anything else) will continue to work, but then it is up to you to keep it in
+> sync with the environment used in CI. Nix unifies the development environment
+> for everyone and synchronizes updates, which is why we recommend it.
 
-```
+### macOS: managing the Apple Clang version
+
+Because the Nix shell uses the system-wide Apple Clang on macOS, the compiler
+version is whatever your installed Xcode (or Command Line Tools) provides. The
+following command should return a version greater than or equal to the
+[minimum required](#tested-compiler-versions):

+# Troubleshooting Nix problems
+
+Common issues encountered when using the [Nix development shell](./nix.md), and
+how to resolve them.
+
+## Git worktrees
+
+If `nix develop` fails with an error like:
+
+```
+error:
+       … while fetching the input 'git+file:///path/to/rippled'
+
+       error: opening Git repository "/path/to/rippled": unsupported extension name extensions.relativeworktrees (libgit2 error code = 6)
+```
+
+then your Nix is linked against a libgit2 older than **1.9.4**. Git 2.48+ writes
+the `extensions.relativeWorktrees` config entry when a worktree is created with
+relative paths (`git worktree add --relative-paths`, or with
+`worktree.useRelativePaths=true`), and older libgit2 versions refuse to open a
+repository that uses it. Nix uses libgit2 to read the flake, so evaluation
+fails.
+
+> [!IMPORTANT]
+> This entry is written to the **shared** repository config, so once any
+> relative worktree exists, `nix develop` fails in the main checkout too — not
+> just inside the worktree.
+
+### Workarounds
+
+These work today, with any Nix version:
+
+- bypass libgit2 with a `path:` flakeref: `nix develop "path:$PWD"`
+  (note: this copies the working tree to the store and ignores `.gitignore`); or
+- create worktrees with absolute paths (omit `--relative-paths`); or
+- clear the extension if you don't need relative worktrees:
+  `git config --unset extensions.relativeWorktrees`.
+
+### Permanent fix
+
+The fix is in [libgit2 1.9.4](https://github.com/libgit2/libgit2/releases/tag/v1.9.4),
+so the real solution is a Nix that links against libgit2 `1.9.4` or newer. Check
+which version yours links against:
+
+```bash
+nix-store -qR "$(readlink -f "$(command -v nix)")" | grep libgit2
+```
+
+> [!WARNING]
+> `nix upgrade-nix` does **not** help yet. It installs the build from the
+> official [`nix-fallback-paths`](https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/installer/tools/nix-fallback-paths.nix),
+> which is still linked against libgit2 `1.9.2` — there is no new upstream Nix
+> release with the fix. (On some systems that build is even the exact store path
+> you already have, making the upgrade a no-op.)
+
+nixpkgs has already rebuilt Nix against the fixed libgit2 (e.g. `nix-2.34.7+1`),
+so the cleanest path is to reinstall Nix using your usual installation method
+once it picks up that rebuild, then re-run the `grep libgit2` check above to
+confirm it reports `1.9.4` or newer.
+
+Until then, prefer the workarounds above.
