 ```
 
-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).
+#### Custom profile
 
-#### Add xrplf remote
-
-Run the following command to add the `xrplf` remote, which hosts some of our dependencies:
+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 remote add --index 0 --force xrplf https://conan.ripplex.io
+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++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
+```
+
+#### 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]

+      |                                      ^

+
+The workaround for this error is to add two lines to profile:
+
+```text
+[conf]
+tools.build:cxxflags=['-Wno-missing-template-arg-list-after-template-kw']
+```
+
+#### Workaround for gcc 12

+encounter a compilation error such as:

+
+The workaround for this error is to add two lines to your profile:
+
+```text

+
+#### Workaround for clang 16

+as:
+
+```text

-# 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.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/${recipe}
-done
-git fetch origin master
-git checkout master
-
-./export_all.sh
-cd ../../
-```
-
-In the case we switch to a newer version of a dependency that still requires a
-patch or add a new dependency, it will be necessary for you to pull in the changes and re-export the
-updated dependencies with the newer version. However, if we switch to a newer
-version that no longer requires a patch, no action is required on your part, as
-the new recipe will be automatically pulled from the official Conan Center.
-
-> [!NOTE]
-> You might need to add `--lockfile=""` to your `conan install` command
-> to avoid automatic use of the existing `conan.lock` file when you run
-> `conan export` manually on your machine
->
-> This is not recommended though, as you might end up using different revisions of recipes.
-
-## Conan profile tweaks
-
-### Missing compiler version
-
-If you see an error similar to the following after running `conan profile show`:
-
-```text
-ERROR: Invalid setting '17' is not a valid 'settings.compiler.version' value.
-Possible values are ['5.0', '5.1', '6.0', '6.1', '7.0', '7.3', '8.0', '8.1',
-'9.0', '9.1', '10.0', '11.0', '12.0', '13', '13.0', '13.1', '14', '14.0', '15',
-'15.0', '16', '16.0']
-Read "http://docs.conan.io/2/knowledge/faq.html#error-invalid-setting"
-```
-
-you need to create `$(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.

-## Linux and macOS

-the Nix development shell. It provides the exact tooling used in CI — `git`,
-`python`, `conan`, `cmake`, `clang-tidy`, `clang-format`, and everything else —

-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

+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".

 This guide explains how to use Nix to set up a reproducible development environment for xrpld. Using Nix eliminates the need to manually install utilities and ensures consistent tooling across different machines.
 
-**The Nix development shell is the recommended way to develop xrpld.** It unifies the development environment for everyone and synchronizes updates: the same tooling and compiler versions are used both here and in CI. 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.
-
 ## Benefits of Using Nix
 
 - **Reproducible environment**: Everyone gets the same versions of tools and compilers
-- **Matches CI**: The Linux CI runs in Docker images built from this exact Nix environment
 - **No system pollution**: Dependencies are isolated and don't affect your system packages
 - **Multiple compiler versions**: Easily switch between different GCC and Clang versions
 - **Quick setup**: Get started with a single command

-
-- **Linux**: `nix develop` gives you a shell with all the tooling necessary to
-  develop xrpld and with GCC 15.2 (also provided by Nix). There are no caveats.
-- **macOS**: `nix develop` gives you a full environment too. The compiler is
-  your system-wide Apple Clang, while every other tool — including Conan — is
-  provided by Nix. Conan has no binary in the Nix cache for macOS, so it is
-  built from source the first time you enter the shell, which makes the initial
-  setup slower (this is handled automatically; see
-  [`nix/devshell.nix`](../../nix/devshell.nix)).

+`nix develop` opens bash by default. If you want to use another shell this could be done by adding `-c` flag. For example:
 
 ```bash
-# Use zsh
 nix develop -c zsh
-
-# Use fish
-nix develop -c fish
-
-# Use your login shell
-nix develop -c "$SHELL"
 ```
 
-> [!WARNING]
-> Your shell's interactive startup files (e.g. `config.fish`, `.zshrc`) may prepend other directories — most commonly Homebrew — to `$PATH`, which can shadow the tools provided by the Nix shell. After entering, verify that tools resolve into the Nix store:
->
-> ```bash
-> command -v cmake   # should print a /nix/store/... path
-> ```
->
-> If it doesn't, either adjust your shell configuration so it doesn't override `$PATH`, or use [direnv](#automatic-activation-with-direnv) (below), which loads the environment _after_ your shell config and so takes precedence regardless of the shell you use.

-# 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.

-# Nix CI Docker images
-
-This directory builds the Docker images used by xrpld's Linux CI. Each image
-bundles the **exact same toolchain that the Nix development shell provides**
-(see [`docs/build/nix.md`](../../docs/build/nix.md)), so what runs in CI matches
-what developers get locally from `nix develop`.
-
-The toolchain (CMake, Ninja, Conan, GCC, Clang, clang-tidy, the
-sanitizer/coverage tools, …) is defined in [`nix/packages.nix`](../packages.nix)
-and assembled for CI by [`nix/ci-env.nix`](../ci-env.nix). The Docker build
-turns that Nix environment into an ordinary container image layered on top of a
-conventional base image (Ubuntu, Debian, RHEL, or `nixos/nix`).
-
-## Images
-
-The images are built by the [`build-nix-images.yml`](../../.github/workflows/build-nix-images.yml)
-workflow and pushed to `ghcr.io/xrplf/xrpld/nix-<distro>`. The `<distro>` is
-selected through the `BASE_IMAGE` build argument; the base images are the
-**oldest supported version** of each distribution we target:
-
-| Image        | `BASE_IMAGE`                                 | Notes                                              |
-| ------------ | -------------------------------------------- | -------------------------------------------------- |
-| `nix-nixos`  | `nixos/nix:latest`                           | Build/lint only; binaries are not run (see below). |
-| `nix-ubuntu` | `ubuntu:20.04`                               | Oldest supported Ubuntu (glibc 2.31).              |
-| `nix-debian` | `debian:bookworm`                            |                                                    |
-| `nix-rhel`   | `registry.access.redhat.com/ubi9/ubi:latest` |                                                    |
-
-All images carry the full toolchain on `PATH` (via `/nix/ci-env/bin`) plus the
-CA bundle shipped in the Nix environment, so HTTPS clients (git, curl, Conan)
-work without `ca-certificates` being installed in the base image.
-
-## Build stages
-
-[`Dockerfile`](./Dockerfile) is a multi-stage build:
-
-1. **`builder`** — On a `nixos/nix` builder, evaluate the flake and build the
-   CI environment (`nix/ci-env.nix`). The resulting Nix store closure (the
-   complete set of store paths the toolchain depends on) is copied into a
-   staging directory.
-2. **`final`** — Start from `BASE_IMAGE`, copy in the Nix store closure and the
-   `ci-env` symlink tree, and wire up `PATH` and the CA bundle. It then:
-   - installs the dynamic linker if the base image lacks one (see
-     [How libc is handled](#how-libc-is-handled)),
-   - runs [`bin/check-tools.sh`](../../bin/check-tools.sh) to verify every
-     expected tool is present and runnable, and
-   - compiles the C++ test programs in
-     [`test_files/`](./test_files) with both `g++` and `clang++`, and sanitizers.
-3. **`tester`** — Start again from a clean `BASE_IMAGE` (no Nix toolchain),
-   install only the sanitizer runtime libraries
-   ([`install-sanitizer-libs.sh`](./install-sanitizer-libs.sh)), and run the
-   binaries compiled in `final`. This proves the binaries built with the Nix
-   toolchain actually run on a vanilla base image. On `nixos/nix` this step is
-   skipped (the binaries are patched for a conventional FHS loader).
-4. **Output** — The final image is gated on the tester succeeding: it copies a
-   sentinel file out of `tester`, so a failed test run fails the whole build.
-
-## How libc is handled
-
-The goal is for binaries built in these images to run on the **oldest supported
-base image** (Ubuntu 20.04, glibc 2.31) and newer — without the developer's Nix
-toolchain being present at runtime. Two pieces make that work:
-
-- **Compilers linked against an old glibc.** The Nix CI environment does not use
-  nixpkgs' current glibc. Instead it pins a 2020 nixpkgs snapshot whose primary
-  glibc is **2.31** (matching Ubuntu 20.04), via the `nixpkgs-custom-glibc`
-  flake input. GCC, Clang, binutils and compiler-rt are all rebuilt/wrapped
-  against this custom glibc (see [`nix/ci-env.nix`](../ci-env.nix)). As a result
-  the libraries they emit (`libstdc++`, `libgcc_s`, the sanitizer runtimes)
-  reference only symbols available in glibc 2.31.
-
-- **An expected dynamic linker in the image.**
-  Binaries built in Nix environments reference a dynamic linker from Nix store paths, which won't be present in the base image. However,
-  [`loader-path.sh`](./loader-path.sh) reports the expected loader path for the
-  current architecture, so we can patch the binaries to use the correct loader.
-
-The build then verifies all of this end to end: the test programs in
-`test_files/` (a regular binary plus ASan/TSan/UBSan variants) are compiled in
-`final`, their `PT_INTERP` is patched to the target loader, and they are run in
-the clean `tester` stage to confirm each emits the expected sanitizer
-diagnostic on a stock base image.
-
